SLDASM to STL

[truly_bent]

Step 1: Save assembly (SLDASM) as part (SLDPRT). Be sure to select All Components radial button (see image). This puts all the parts into one file.
Step 2: Open the part file (SLDPRT) and save it as an STL file. You have some control over this process in the Options popup window.





This particular example is an assembly of 22 parts. The resulting STL file was uploaded to Shapeways. Here's a Youtube video of the motion study.
