From the
Model section of the
action bar,
click
Sheet Metal Parameters
.
To define the standard to use with the 3D shape, click
.
The name of this standard file is defined in a design
table.
Optional: In the Thickness box, enter a
value.
Optional: In the Bend
Radius box, enter a value.
It corresponds to the internal radius and by default, it is linked to
the creation of the bends.
Important:
The inner
angle between two elements is used to define the bend. It can vary from 0°
to 180° exclusively. This angle is constant and the bend axis is
rectilinear.
In the Unfold method area, select the unfold method, and
specify its parameters:
Option
Description
K-factor
Defines the neutral fiber position inside the thickness, from the inner side of the bend.
Bend Allowance
The bend allowance corresponds to the unfolded bend width.
Bend Deduction
The bend deduction represents the sheet metal deformation when the bend is unfolded.
Bend Table from Standards
Uses the bend deduction table defined in the standards. You must select a standard
containing a bend deduction table.
Notes:
The Bend Table from Standards unfold method
is automatically selected if a bend deduction table is present in
the main sheet metal design table. If you do not want to select this
method, you must change to a design table that does not contain a
bend deduction table.
This functionality is also applicable to features created before R2022x GA after the unfold method is modified for the first time.
To modify the K-factor, use the formula editor or the
DIN formula.
In the
Bend extremities
list, select one of the following:
Option
Description
Minimum with no
relief
The bend corresponds to the common area of the supporting
walls along the bend axis, and shows no relief.
Square relief
The bend corresponds to the common area of the supporting walls along the bend axis, and
a square relief is added to the bend extremity. You can modify the
Length 1 and the Length 2 parameters if required.
Round relief
The bend corresponds to the common area of the supporting walls along the bend axis, and
a round relief is added to the bend extremity. You can modify the Length
1 and the Length 2 parameters if required.
Linear
The unfolded bend is split by two planes going through the
corresponding limit points (obtained by projection of the bend axis onto the
edges of the supporting walls).
Tangent
The edges of the bend are tangent to the edges of the
supporting walls.
Maximum
The bend is calculated between the furthest opposite edges
of the supporting walls.
Closed
The bend corresponds to the intersection between the bends
of the two supporting walls. The closed bend extremity lies on the surface of
the encountered bend.
