I'm new to using toolbox and I was wondering if anyone can help me out. How can I use the steel members within toolbox as a normal structural member? That is, start a part, draw a 3d sketch, choose "structural member," and point to the lines of my sketch in groups to define what member it should be - just like I would do with angle iron, c-channels, steel tubes, etc. I cannot seem to do that with the unistrut member that's found only in toolbox. Any help would be appreciated. Thanks.
