ABOUT THIS MANUAL
This manual is destined to bring a precise aid for specific 3D construction
problems.
It is complementary to the ModEva User Guide manual.
The User Guide manual gives the procedure to be followed for creating a
3D product.
This manual is organized like a dictionary.
That is the items are in alphabetical order. If a subject is treated in a chapter
other than the one you are consulting you will find a cross-reference of the
new subject.
The index situated at the end of the manual will help the search for
information.
This manual only treats the 3D graphics relative to the ModEva
software.
The topics concerning other parts of the software are dealt with in the
ModEva 2D Reference manual.

MEASURING
At the bottom of the dimensioning table, PRODUCT 3D pages (MODIFY

the dimensions of the product.
See also Dimensions.
By clicking on the symbol, its appearance changes depending on the type of
measurement (3 possible selections).
The 3 types of symbols:
Cartesian co-ordinates (in the text = ).
Polar co-ordinates (in the text = ).
"Callipers" type of measurement.
The co-ordinate measurements are always made between the origin of
the product (displayed by a small square) and the origin of the active
violet segment (displayed by a small violet circle).
The calliper mode of measurement is made from face to point, as callipers
would.

One click, switches the YES ⇔ NO field.
Click LEAVE to validate the data and close the window.
INTERNAL CUT
PRODUCT 3D / MODIFY 1W and MODIFY 2W page
Function
Allows to create a cut inside the product.
Procedure
:
:
Click on this pictograph.
Click on the segment where the peduncle is to be placed.
By default the peduncle is placed at 90° to the construction segment.
If the cut is not placed at the required spot , click on ABANDON in
the dimensioning window and start again (see Abandon).
Enter the values in the dimensioning window.
A and B are used to adjust the starting position of the peduncle on the
construction segment.
(The segment on which the cut has been "inserted" has been automatically
divided into two segments A and B whose sum is equivalent to the former
segment).
C is the distance between the construction segment and the hole (the segment
C is called the peduncle).
D and E define the size of the hole.
F is the angle between the segment C and the hole.
G is the angle between the segment C and the segment B.
The peduncle is an element of internal construction.
Physically, it is composed of 2 adjacent segments (separated by 0.05 mm)
connecting the construction segment to the internal cut.
Remark: The internal cut is placed in the face on which is located the
construction segment and face (see below).
PAGE 28 3D REFERENCE MANUAL MODEVA
Example of an internal cut on the external face.
Example of an internal cut with different angl es (F and G values).
Example of an internal cut on the internal face.
To realize a cut as shown in the example above, a certain procedure must be
followed.
P-PICTOGRAPHS PAGE 29
Procedure
General rule: The internal cut must be added immediately after the creation
of the face which "receives" the cut.
In the above example, the cut must be created immediately after the creation
of the base face.
:
The segments must then be attached to the periphe ry.
On the cut’s construction segment, the automatic adaptat ion of the face only
"covers" the semi-segment.
PAGE 30 3D REFERENCE MANUAL MODEVA
The C value of the Rectangle diagram must thus be modified. This value
should be negative and correspond to the value of the second segment to be
covered to obtain the above result.
LEG
Bend 3D page
Allows to select another leg than the one displayed in the current sequence
The software automatically positions the axes and the stop fingers separated
at 80% (or another value defined by the machine parameters) onto the new
leg segment.
It immediately displays the new sheet metal position.
Procedure
If the segment chosen is not valid, or if the cursor is badly placed, the
POSITION BADLY DEFINED message is displayed.
Attention to not leave the graphical window, otherwis e the pictograph is
deactivated.
Remarks:
This function allows to easily and effectively choose the new legs.
A leg defined automatically by the simulation or by the method described
above is called a nominal leg.
In the case where this function does not allow you to put the stops at the
required place, use the

Forced bends under 2 punches
In the case where 2 forced bends must be realized under 2 distinct stations
(punches), there is a way which allows to position automatically the sheet
metal between these 2 punches.
Take the following case:
The bends A and B are defined as forced bends.
See Pictographs: Forced bends.
The 2 stations 1 and 2 are defined on the POS.TOOLS page.

If you click between the 2 punches, the software positions the space between
the 2 forced bends centrally in relation to the space between the 2 punches
(following figure).
To select the space between the 2 punches, it may be necessary to modify the

PRODUCT DATA
Introduce the product
data
To execute a simulation, a calculation etc. the software needs the product
data.
It is thus convenient to start the construction of the product by introducing
these data.
Click on the PRODUCT DATA field.
For more details on the procedure, please refer to the section Starting
construction of a 3D product.
SEGMENT
A segment is a part of the product outline which joins two apexes.
It is a straight whose length is defined when introducing the data.
Each segment can be selected.
A segment can be:
Split in two (see Pictographs: Vertex).
Modified, lengthened (see Pictographs:Stretch).
Used as a support for the construction of other elements (see
Pictographs: Rectangle / Trapezium / Internal cut).

segment or use the
or keys.
Construction segment
The construction segment is a "reception" segment on which is added a
rectangular face, a trapezium, a vertex, the peduncle of an internal cut and /
or the extremity of a bend.
Superimposed segments
Depending on the construction operations, it is possible that several segments
are superimposed. Sometimes this situation is necessary, sometimes it is the
result of bad manipulations.
Superimposed segments cannot be activated (vi olet) using the mouse, but
only by using the
Deleting a superimposed segment
or keys.
Use the or keys to activate the required segment then proceed to
delete it as described in Pictographs: Eraser by clicking on the acti ve
segment.
Constructing a superimposed segment
Use the or keys to activate the required segment then select the
relevant construction pictograph and proceed normally by clicking on the
active segment.
PAGE 56 3D REFERENCE MANUAL MODEVA
Collinear segments
The collinear segments are segments which are an extension of each other
and give the impression of being a single segment. This situation comes
from, as in the case of superimposed segments, successive modifications.
These segments are usually useless.
To detect collinear segments, simply scroll the current segment along the
whole length of the outline.
The situation below shows two collinear segments.
To delete the superfluous segment, refer to Pictographs: Eraser.
