This manual describes the CYCAD option which allows the PC1200 to read
and convert DXF and IGES files for use on PC1200.
This manual addresses operators having a working knowledge on CAD
systems. It is necessessary for these persons to also be familiar with the
PC1200 software, to know how to create products with this software and to
have read the PC1200 user guide.
This manual can evolve, it is you, the operators, who can help us to help you
more. If you have any remarks concerning this manual, please write to us at:

NTRODUCTION
I
The CYCAD option offers conversion possibilities between DXF or IGES
files generated by a CAD programme such as Autocad, CADKey, HiCad etc
and files accepted by the numerical controls DNC 80/800/900/1200 from
CYBELEC (in both directions).
The DXF (IGES) file describes the product in its entirety so that after
conversion the DNC will be able to fully exploit that product. Use of the
CYCAD conversion program, in conjunction with a CAD program, will bring
about the following gains:
! You can use an existing drawing directly on a DNC, without having to
re-programme the product.
! It is possible to include such attributes as holes and circles on the
drawing - a feature not supported by the DNC.
! You can employ all the familiar CAD techniques to develop your
drawing.
! Carrying out modifications on a drawing will be easier than on the
DNC. For example, you can re-shape the product even after the bends
have been defined.
Examples Several example files in the DXF and DWG formats are available on the
CYCAD diskette. Should this diskette be missing, do not hesitate to request it
from our After Sales Service.
Allow yourself some time to open these files with your CAD system and with
PC1200 / CYCAD. In each example, one or several particular cases are
shown in detail. You will find the names of the example files in the sections
where each particular case is mentioned.

You can also convert an existing file (.DAT file) into a DXF (IGES) file that
can be used with a CAD program.
The drawing conventions for the DXF (IGES) file are strictly the same for
both conversion directions.
The CYCAD option allows two different working approaches:
conversion of "untreated" CAD files and
conversion of "prepared" CAD files.
These two possibilities with their advantages and inconvients are summarized
hereafter.

"CYBELEC" format.
add missing information if necessary, test the feasibility of the product
and then transfer it to the numerical control.
C
ONVERSION OF "UNTREATED
CYCAD is capable of reading "untreated" DXF files, i.e. files that have been
converted in the state in which they have been created in the CAD system,
without the conventions described hereunder being applied.
From the CAD INTERFACE page of the PC1200 software, the program
filters certain unwanted information and displays the contents of the CAD file
which will need to be "purified" and in which it will be necessary to select the
elements needed by PC1200 (see Use of CYCAD section, page 25).
Existing CAD files The advantage is that existing DXF or IGES files can be converted without
having to any work on them at CAD level. This is particularly convenient
when the files have been generated on a system which is not available in the
company.
However, such a file must be a 2D file, for CYCAD does not recognize
3D files. Furthermore, the file must contain at least the outline of the product
and respect a certain number of limitations described in the CAD Drawing
Conventions section, page 9.

PAGE 6 PC 1200 / CYCAD
C
ONVERSION OF "PREPARED
If the drawing conventions have been respected during creation of the
products on the CAD system, the CYCAD converter is able to automatically
insert the information at the correct locations (see CAD Drawing
Conventions, page 9).
Conversion speed Preparation of the CAD file may seem a bit long because the drawing
conventions must be respected, but the conversion is greatly facilitated. The
operator will need to spend much less time (if any) in the CAD INTERFACE
page of PC1200, and the product can be "taken over" by PC1200 much faster.

RAWING CONVENTIONS
The drawing is organized into various levels, of which just three are relevant
to CYCAD.
! The first pre-defined level describes the overall shape of the product,
with general data on it. This is called OUTLINE.
! The second pre-defined level defines the bends and associated data.
This is called BENDS.
! The third (optional) pre-defined level contains section and order of
bending data, together with support details. This is called
SECTIONS.
You may use the other levels for your own needs. The conversion program
simply ignores the levels which are not needed. It is recommended to assign
particular colors or line types to the various levels. An example file treated
this way can be found on the CYCAD diskette. The file names are
EX_CY.DWG (for AutoCAD) and EX_CY.DXF.
At this stage it is helpful to remember that the notion of sectioning a product
is not critical when designing it. It is not necessary to indicate section
positions, since they are generated automatically by the conversion
programme. If however the section location becomes important (eg. in
determining the support position) you can in fact indicate it.
Hint CYCAD is capable of exporting products created on PC1200 in the DXF or
IGES format. It is thus easy for you to create yourself example DXF or IGES
files respecting the CYCAD conventions and export a product with DXF or
IGES format to look at them in your CAD system. See Exporting a File in
DXF or IGES Format, page 30.

Texts:
The character type (font) and the size of the
characters is unimportant.
When the position of the text is relevant, the
lower left corner of the text is taken into
account.

T
HE
"OUTLINE"
LEVEL
The text CYCAD : OUTLINE (in upper case characters) must be present for
the level to be correctly identified.
P
RODUCT OUTLINE
The product shape must be defined as a series of lines and connected arcs.
The outline of the product must be entirely closed (no open ends). The shape
will correspond to that drawn on the PRODUCT FLAT page of PC1200.
Arcs In the moment of conversion, the arcs are converted into a series of segments.
The number of segments corresponding to an arc can be specified by the user,
as indicated in the Setting Parameters for CYCAD / PC1200 Option section,
page 17.
The order in which the lines and arcs are drawn is unimportant; they must be
simply end-to-end in the sense that each "summit" on the drawing must
correspond to the junction of two lines/arcs. The total of these lines/arcs must
not exceed 300 before conversion.
I
NTERNAL CUTS
You may draw cut-outs inside of the product outline in the same way as the
outline, by means of lines and connected arcs. The external outline as well as
the cuts must be closed shapes. It is, of course, necessary to take into account
the max. number of segments (300).
An example of internal cuts can be found in the EXAMPLE1.DXF file. You
can convert this file and see the result in PC1200.
If the the internal cut-outs are not really necessary for the comprehension or
for the recognition of the drawing, and if they are not to be "worked on"
(bend within the internal cut), it is recommended to put them into a nonCYCAD layer so that they will not appear in the product destined to PC1200.
P
ARAMETERS
Optionally, it is also possible on the Outline level to indicate various
PC1200 parameters. You may specify just those values useful to you and omit
the others. Each parameter is defined by an independent text, and the position
of the text is unimportant. To define a parameter, write the corresponding
keyword, the character = preceded and followed by a space and its value,
which can either be a number or a text, according to the parameters.
PAGE 10 PC 1200 / CYCAD
! For real numbers (REALS) you may use the "minus" sign and the
decimal point.
! "Whole" numbers (INTEGERS) are composed of figures only (0 - 9),
including, if necessary, the minus sign.
! The length of the texts is limited to 25 characters.
The list of usable parameters and their associated keywords is given below:
Do not use any spaces inside the keywords. As an example, it is not
acceptable to write D I N instead of DIN.
BHead = <texte>
DefAngle = <real>
Die = <text>
DIN
Inch
Name = <text>
Punch = <text>
Radius = <real>
ScaleX = <real>
ScaleY = <real>
Sigma = <real>
Thick = <real>
Example:
Thick = 2.00
Punch = P12-3-30
Die = M10-30-1
etc.
For folding presses only: corresponds to the
name of the folding tool.
Defines a default angle for any angles that have
not been specified in the Bends level.
Name of the die, or of the lower tool in the case
of a folding press.
Indicates that dimensions are 'post bending'.
Indicates that dimensions are expressed in
inches.
Product name.
Die name, or name of the upper tool in the case
of a folding press.
Internal bending radius.
Horizontal scale factor (1.0 = no deformity).
Vertical scale factor.
Sigma (...).
Thickness of the metal sheet.
Note: the text items must be placed on a vertical line, as shown in the
above example.
Example To obtain an example on how these paramters are used, export a file with
DXF or IGES format and look at it with your CAD system. You can also see
the EX_CY.DXF file on the CYCAD disquette.

ENDS
The text CYCAD : BENDS (in upper case characters) must be present.
This level must include product bends in the form of a set of lines.
Simple bends:
" L
EVEL
The bend line must intersect with the edge of
the product in 2 places (not more, not less).
You may use outline points as terminating
points for bends. If a line has to cut a
component of the outline, its endpoint can
either be on the outline itself or can overshoot.
Forced bends:
Internal bends:
The bends can cut the outline at several points.
All bends thus defined will effectively be
actioned simultaneously. It is equally possible
to define forced bends with unjoined lines. For
this the lines must be aligned and 'barred'
evenly (see example "EXEMPLE2.DXF").
Note: This is possible only for vertical or
horizontal bends.
Bends which do not cut the outline but are near
of the terminating points of it (at a distance
smaller than 2 % of the largest dimension of the
product), are treated differently. In order to be
integrated into the product, the program
modifies the outline by creating additional
points to join the bending line (see example
"EXEMPLE3.DXF"). In order to perfectly
understand this example, it will be useful to
convert EXEMPLE3.DXF and to view the
result in the 3D construction page (MODIFY
3D). Also see the illustration below.
Contour/Outline/Umriss
Contour/Outline/Umriss
Pli/Bend/Biegung
Drawing not at scale
Max number of bends The maximum number of bends allowed is 35, less the number of sections.
Furthermore there must not be more than 15 distinct orientations for these
bends. You may thus have a maximum of 15 groups of parallel bends.
PAGE 12 PC 1200 / CYCAD
Pli/Bend/Biegung
Angle values Optionally, you may also indicate on this level the various bend angles.
Certain bends can be left unassigned to particular angle values.
The angle values are indicated, as in the case of OUTLINE, with the aid of
texts. These texts amount in fact to numbers (not keywords) and they must
appear approximately in the middle of each bend, also in the case of a forced
bend. Each value is recognized as belonging to the bend which is physically
closest to the leftmost extremity of the text.
You are advised to avoid the use of over-large characters so as not to overfill
your drawing. You may also indicate for each bend its associated tool (punch
and die) and the internal radius. To this end you write after the angle:
C=<integer>
D=<text>
P=<text>
R=<real>
H=<text>
I
You may write partially or completely this set of fields and in any order. The
field delimiting character is the '/'.
No space must be inserted after the "equal" sign.
You may also write the instructions in several separate texts for each bend.
Example: 90.5 / D=M1 / R=3.1 / C=5 / P=P1
This stream of data indicates that the bend's angle is 90.5 degrees,
that it uses die M1, punch P1 has a radius of 3.1 mm and that there
are 5 units of ideal curve.
Ideal curve (number of bends)
Name of the die or, for a folding press, name of
the lower tool
Name of the punch or, for a folding press, name
of the upper tool.
Internal bending radius.
For a folding press only: corresponds to the
name of the folding tool.
(I for India) For folding presses only:
designates an inversed bend.

The text "CYCAD : SECTIONS" (in upper case characters) must be present.
Sections:
You can indicate at this level the relevant sections for a
product.
Each section is defined by a line which intersects a
component of the outline at two places. Bends
perpendicular to this section, and crossing it, belong to
this section, and no other.
Bend and
Support Order
UPPORTED ENTITIES
S
You can also specify at this level the bend order and
support positions with the aid of texts. To do this you
write close to the bend's mid point the letter 'b', followed
by a number (eg. b1, b2 & b3). You should begin with
number 1, and subsequently continue in exact sequence,
leaving no gaps - for example going from 5 to 7.
The support is indicated by writing the letter 's' followed
by the same number as the corresponding bend either
near the middle of an existing bend or near the middle of
a segment of the product outlinef (e.g. s1, s2, s3). For
machines equipped with front gauges, the contact point
with the front gauge must be indicated with the letter 'e'
followed by the number of the corresponding bend (e.g.
e1, e2, e3).
You are not obliged to indicate the sequence number of
every bend, but each time you do, you must also indicate
its support (see example EXAMPLE4.DXF).

CYCAD
As seen in the Working Method section, it is possible to import "untreated"
files or files "prepared" for CYCAD.
Hereafter, the import procedure for "untreated" files is explained because this
procedure needs the most handling at CYCAD level. "Prepared" files can be
imported exactly in the same fashion; they simply need less work to be done
at CYCAD level.
General Procedure
! Click on the ACTIONS menu or press function key F5.
! Import the unprepared DXF file (CAD """").
! The following window appears, allowing you to navigate in the
different directories of your system.
! Select the outline and move it to the Outline level.
! Select the bends and move them to the Bends level.
! If other indications, such as angle values, tools, material etc. are
available, and provided that they are comply with the CYCAD
prescriptions, you can also move them to the corresponding levels.
! If necessary, simplify the outline of the product in the Outline level.
! Convert the file into a PC1200 product (PRODUCT ####).
! In the PC1200 program, you can, if necessary, add missing
information such as material, tools, tool position, etc.. Then you test
the feasibility of the product as you would do with any other product
created directly with PC1200.

In this section you find a step-by-step description of the import procedure for
an "unprepared" CAD file. For this example, the file named EX_ORI.DXF
contained in the disquette will be used. Open this file with your CAD system
to see the original DXF file.
You will notice that this file does not have any specific level, nor any
particular text corresponding to CYCAD standards. However, it contains the
bending lines with the values of their angles and - this is the only CYCADspecific item - three small oblique lines across the bending line of the upper
part of the product, indicating that this will be a forced bend (see further on in
this manual).

If the outline of the product contains a large number of small segments which
are unimportant for the bending of the product, it may be useful or necessary
(max. number of bends reached) to simplify the outline. In the example used,
the two small notches of 5 x 5 mm will be used. The distance between the two
notches is 12 mm.

On the CYCAD Example files diskette several example files are available.
Take the necessary time to open them and to have a look at them in your
CAD system. This is particularly useful to understand the use of the different
levels.
The disquette also contains a number of converted products which can be
read directly with PC1200. The numbers PRODUCT 20000 (to 20055)
designate the corresponding PC1200 product numbers.
The following files can be found on the disquette:

DXF files relating to the Problems and
solutions section (page 33).
On this disquette are also some sample DXF
files already converted.
The EX_CY.DXF file is the same as EX_ORI.DXF, but it has been prepared
for CYCAD at CAD system level. When looking at this file with your CAD
system, or importing it into CYCAD, you can see that the outline, the bends
and the angles have been placed in the levels according to CYCAD
"standards", and that information using CYCAD keywords have also been
integrated. Because of this, the file can be converted after having been
imported directly into a PC1200 product (PRODUCT#### key) without having
to work on it by means of the CYCAD interface. It will, however, still be
necessary to add in PC1200 the missing information and to test the feasibility
of the product.
U
SE OF THE SAMPLE DISQUETTE
In order not to modify your existing environment, the disquette has also been
made in such a way that it can be read directly by PC1200. To this effect, the
disquette contains the machine parameters and tools making it possible to
visualize the converted sample products.
To read information directly on the disquette from PC1200:
! Call the WELCOME page.
! Select ACTIVE PERIPHERALS = FLOPPY.
(See also: 2D Reference Manual).
In the CAD INTERFACE page, access the DXF example files by choosing
the DXF_A peripheral.
Note: The 3.5" disquette unit must be A:
If this is not the case, you must modify the machine parameters page

ROBLEMS AND SOLUTIONS
P
When using CYCAD, it may happen that the software does not react in the
way you are expecting. In such cases, the present section may be useful, for it
explains the most frequently problems encountered..
On the CYCAD disquette, in the PROB directory, you will find several
DXF example files which may cause problems. They are described in the
corresponding sections.
RDER OF SECTIONS
O
CYCAD converts the sections in the order of construction. The section
established first will be given the numer 1, the second the number 2 etc. If
there are numbered sections in the CAD drawing, this numbering will be
ignored.
The order of the sections influcences the bending order, because PC1200
starts with section 1.
PROB2.DXF shows a DXF file where the sections were created in the
following order: 1 horizontal, 2 vertical. However, the numbering has been
"inverted", i.e. the vertical section was given the number 1, and the horizontal
section has number 2.
If you import this example file, you will see after conversion that
(PRODUCT FLAT) section number 1 is the horizontal and section 2 the
vertical section. They do correspond to the order of construction.
The PROB3.DXF file is identical to PROB2, but the vertical section was
created first, followed by the horizontal section as a second step.
You can import this example and see the difference in the PRODUCT FLAT
page.
ENDING LINES
B
The bending lines must be continuous lines, because on certain CAD systems
a "dotted" line is considered to be a multitude of short lines.
It is indispensable that the bending lines touch the outline at both extremities,
otherwise the line will not be converted.
The PROB7.DXF file shows a product with a "dotted" bending line. It is not
possible to select the line in a single operation, and even if each element is
selected, this bending line will not be converted.
The PROB8.DXF file shows a bending line which does not touch the outline
(top). During conversion, this line is ignored and will be lost.
Solution:
The only remedy is to make the necessary changes at CAD level.
PROBLEMS AND SOLUTIONS PAGE 33
PEN OUTLINE
O
The conventions specify that the outline of a product must be closed. CYCAD
does not signal any particular error if this point is not respected. To the eye,
an outline may seem to be closed even if it isn't. This problem will show up
after conversion in the PRODUCT FLAT or PRODUCT 3D page.
The PROB4.DXF illustrates this explanation. The outline is not closed in the
upper left corner. To see the "gap", it is necessary to zoom extensively, for
the opening is only 0.05 mm wide. See also PRODUCT 20054 on the
CYCAD Example files disquette.
The PROB6.DXF file provides another example of an unclosed outline. In the
upper right corner, the two lines are crossing each other (exaggeratedly for
this example) but they have not been declared as closing the outline.
During conversion, the system will close the outline by using the extremity of
either one of these lines, and the outline will be incorrect. In this example, a
side-effect will be that the bending line no longer touches the outline at one
extremity and will therefore not be converted (see Bending Lines).
Solutions:
1.- Open the file with a CAD system and correct it by closing the outline.
Note: The outline of the internal cuts must also be closed.
2.- Use the functions at disposal:
Create segment
Lengthen segment
Trim two crossing
segments
ROSSING BENDS
C
The conventions do not allow bends to cross each other. Sometimes, the eye
cannot distinguish that bends are crossing. The product will be converted
without any particular message being issued. The error will be found in the
PRODUCT 3D page. The product will not be displayed, and the message Crossing Bends will be shown. The product can be seen in the BEND 2D
page.
Creates a straight segment between 2 lines.
A click close to a point creates the end of the segment on this
point. The segment is created in the same level as that of the
first line.
Click on a line which becomes the support straight line.
Click on another line. This line is lengthened, so that it cuts
the support straight line.
Click on a segment which becomes the support. Click on the
segment which crosses. The selected part of the 2
is eliminated up to the intersection with the support segment.

The PROB5.DXF file illustrates an example with crossing bends. The upper
horizontal bend is too low by a value of 0.01 mm. See also
PRODUCT 20055 on the CYCAD Example files disquette.
PAGE 34 PC 1200 / CYCAD
Solution:
It is recommended to correct the problem at its source. However, since the
product can be displayed in 2D, this product can be worked on, but only in
2D. Depending on the value of the error, it will be necessary to correct the
backgauge axis.
UPERPOSED LINES
S
It may happen that you cannot select a line, or that only part of a line is being
selected.
Sometimes, during construction of a product, some construction lines remain
in the file. They are "hidden" but they may cause you some surprises when
selecting or converting items.
The PROB9.DXF file gives a small example of the phenomenon you might
encounter.
On the outline, two supplementary lines have been superimposed.
One is located on the vertical left line, the other one on the upper horizontal
line. The vertical line has the same length as the line it covers, the horizontal
one is shorter.

! Activate the
to be impossible to select it.
! Now try to do the same with the upper horizontal line. You will see
immediately that it is shorter.
Solution:
Remember that one click activates the selected object, and that the subsequent
click de-activates it. The reaction can be different depending on the fact
whether the supplementary line is situated on top of or underneath the line of
the drawing.
In the case of the vertical line, select the
the vertical line. Even though it is of blue color and does not seem to be
selected, click the eraser
Proceed in the same way with the horizontal line.
Maybe you are not sure whether you have chosen the right line. In this case,
instead of erasing to line, you just transfer it into the Auxiliary level. Then
you mask it and check the situation.

OT RECOGNIZED LEVEL
N
If, after having read a CAD file, the elements are not "placed" automatically
in the correct levels, and if the indications CYCAD : OUTLINE or
CYCAD : BENDS (or other similar information) are visible, check the
following points:
!!!! Outline level
- Only the outline and possible reserved keywords may be seen in
this level.
- The text CYCAD : OUTLINE must be written on one single line.
- The text CYCAD : OUTLINE must be written in upper case letters.
- The double point must be preceded and followed by one space.
- The syntax of the reserved keywords must be imperatively
respected (see the corresponding section).
- Make sure you use the decimal point and not the comma.
- The keywords must be placed one on top of the other.
- Make sure the outline is completely closed.
! Bends level
- This level may only contain bending lines and possible reserved
keywords.
- The text CYCAD : BENDS must be written on one single line.
- The text CYCAD : BENDS must be written in upper case letters.
- The double point must be preceded and followed by one space.
- The syntax of the reserved keywords must be imperatively
respected (see the corresponding section).
- In this level, there must not be any space before or after the equal
sign.
- Make sure you use the decimal point and not the comma.
- Place the value angles (and the keywords) in a univocal way near
the related bending line.
! Sections level
- Same remarks (see corresponding section).
Hint In any event, if you have doubts about the syntax, you can create a product
with the PC1200 software and export in in DXF or IGES format so as to
examine it with your CAD system.
OT CONVERTED ELEMENTS
N
It may happen that some elements are not converted. In this case, please make
sure that:
! All levels are visible (not masked) during conversion.
See Masking a level, page 23.
! The element is really located in one ot the 3 levels Outline, Bends
or Sections.
! Both ends of the bending lines really touch the outline (see Bending
Lines earlier in this section). If necessary, check both extremities with
a strong zoom enlargement.
