This section explains how to change the different
sheet metal
parameters needed to create your first feature. |
 |
-
Click Sheet Metal Parameters
.
The Sheet Metal Parameters dialog box is displayed. |
 |
-
Change the Thickness if needed.
-
Change the Default Bend Radius if needed.
The Default Bend Radius corresponds to the internal
radius and is linked by default to the creation of the bends. |
 |
Convention dictates that the inner angle between the two elements
is used to define the bend.
It can vary from 0deg to 180deg exclusive. This angle is constant and
the bend axis is rectilinear. |
-
Click OK to validate the Sheet Metal
Parameters.
|
|
The Standard field
displays the Standard to use with the part, if implemented. The name of
this standard file is defined in a Design Table. |
 |
Parameters can be
defined in a Design Table. To do so, press the Sheet Standards
Files... button to access the company-defined standards, if need be. |
|
All parameters hereafter, or only some of them, can be
defined in this Design Table: |

|
 |
In all cases, the Thickness parameter must be defined in
the Design Table in order for the other parameters to be taken into
account. |
 |
Whenever both Radius Table and Default Bend Radius are defined in the
Design Table, only the Radius Table will be taken into account for the bend
creation. |

Example for a bend allowance table
|
|
A bend table is associated to the default bend radius.
Each bend radius is linked by a formula to the default bend radius. If a
bend table is defined, the bend allowance (for a given angle) is taken into
account when the bend is created. Otherwise, the default K factor is used.
You should know that bend tables are used only for:
- the default bend radius; in the case of a non-standard bend, the K
factor is used by default. In this case, you will need to modify manually
the local K factor if you want the required allowance to be taken into
account.
- the Bend and Bend from Flat features; other features use the K factor
for flat length computation.
