Like the square thread, the Acme has a basic depth equal to half the pitch however, clearance is. Would there have been a good way to build an assembly that would simulated screwing the two parts together?Īnyway, thanks everyone. Autodesk Inventor makes Modelling 3D Threads pretty easy, but this tool from Philippe Leefsma of the ADN makes the process even easier. Acme thread screws are used on milling machines and lathes. I think I worked that out but I won't have a chance to print that part until tomorrow. You can exchange useful blocks and symbols with other CAD and BIM users.

#ACME THREADS AUTODESK INVENTOR 2015 HOW TO#
It also didn't cover how to make the matching "nut". Free CAD+BIM Blocks, Models, Symbols and Details.
Coil feature using the rod as the axis, set up the options to match your needs and the thread specs. Model only the cross-section of 1 thread. Model the cross-section of the thread against the edge of the rod. I could have solved this by not extruding the head until I had cut the thread, but the "head" (which isn't actually the head of a bolt, but an artifact that mates with a fixed-feature "nut") was extruded from the object that mates with the "base" of the project. Model a rod that's your desired length, with the OD of the rod being the minor diameter of the thread. I then extruded the coil into the head, then extruding the circle into the head.
The problem was putting a head on the bolt, and requiring that the nut tighten up all the way to the top (that's not what I'm building, but it is a suitable explanation) Everything that caused the thread to go up to the thread caused it to cut into the head, I solved this by adding a new drawing to the underside of the head, which had a circle centered on the shaft of the bolt.
