Sheet Metal Features
When you click Insert
Bends on
the Sheet Metal toolbar, or click Insert,
Sheet Metal, Bends,
two distinct stages are applied to the sheet metal part.
The part is flattened and a bend allowance is
added. The developed length is calculated, based on the bend radius and
bend allowance.
The flattened part is restored to the folded state
to create the bent version of the part.
Three features appear in the FeatureManager design tree that are specific
to sheet metal operations. These three features represent a process plan
for the sheet metal part:
|
Sheet-Metal
contains the definition of the sheet metal part. This feature stores the
default bend parameter information (thickness, bend radius, bend allowance,
auto relief ratio, and fixed entity) for the entire part. |
|
Flatten-Bends represents the
flattened part. This feature contains information related to the conversion
of sharp and filleted corners into bends.
Each bend generated from the model is listed as a separate feature under
Flatten-Bends. Bends generated
from filleted corners, cylindrical faces, and conical faces are listed
as RoundBends; bends generated
from sharp corners are listed as SharpBends.
The Sharp-Sketch
listed under Flatten-Bends is
the sketch that contains the bend lines of all sharp and round bends generated
by the system. This sketch cannot be edited but can be hidden or shown. |
|
Process-Bends represents the
transformation of the flattened part into the finished, formed part.
Bends created from bend lines specified in the flattened part are listed
under this feature. Flat-Sketch, listed under Process-Bends,
is a placeholder for these bend lines. This sketch can be edited, hidden,
or shown.
Features listed after the Process-Bends
icon in the FeatureManager design tree do
not appear in the flattened view of the part. |
