1. Start BricsCAD in the Sheet Metal workspace, and then open the sample file startfromsolid.dwg.
Solid model with pins and filleted corners
2. Here is the first step of defeaturing, smart selection. While you could perform smart selection at the command
prompt, it is much easier using one of these icons:
ÐÐ
From the Quad cursor, choose Select > Same Area Faces
Choosing the Same Area Faces command from the Quad
ÐÐ
Or, in the Sheet Metal ribbon’s Select panel, click the Same Area Faces button
Finding the Same Area Faces button on the ribbon
3. Ignore the plural nature of the prompt by selecting the face of just one pin:
Select [sUbset/Sample/sEed] : (Press Enter to accept the default, Sample)
Select several entities/subentities: (Pick the face of a pin)
Make sure that you select the face, and not the edge. (If you select the edge of the pin, then BricsCAD selects
all other edges in the model, which you don’t want.)
Selecting the face of one pin...
Notice that BricsCAD selects all other faces that are the same.
