I have several models in Solidworks 2015 that HSM will not recognize threads. When I select the thread segments (edges and faces) there is a persistent no threads selected error. Has anyone run into this? If so, what was a a solution. It should be noted I am not an extraordinarily good Solidworks user. I have verified the correct geometry on the threads in the model, and tried a couple different revisions of the models to make sure it wasn't an isolated problem.<BR /></TD></TR></TBODY></TABLE></BLOCKQUOTE><BR /><BR />Do you want to machine the outer thread that has been modeled?<BR />That the software won't understand.
