[Set up your weldment profile on Solidworks]
Use this file to create a custom "weldments" profile in solidworks.  Add it to the directory where Solidworks locates weldment profiles.  In the main directory, create a new folder called custom.
Filename: profile3030_v5.SLDFLP
Directory: C:\Program Files\SOLIDWORKS Corp\SOLIDWORKS\data\weldment profiles
New Directory: "custom"

[Open up the example part]
I've included a sample part that you can use to test out your weldment profile is properly setup.  This design contains a simple 3D sketch and the weldments assigned to build on this sketch geometry.
