Introduction: Autodesk Inventor - 3d Threading Across Two Shelled Halves
This is a tutorial for how to model 3d threads split across two shelled halves that will align and print with the 3d printer.
I made a mockup of this thing just for a demonstration. It's not perfect and not meant to be.
The model would be 3d printed or injection molded so it needs to be split into 2 halves. But with a threaded hole in the middle there where challenges to getting Invento to cooperate.
The solution I devised was to model the threads with the Thread Modeler tool available from Autodesk.
Create a new file and separate the solid body of the threads later to be reassembled in assembly mode.
Go back to the original half model, shell it and mirror.
Cut a hole the same size in the same place as the threads go.
Create new assembly with model and threads then constrain the threads to the whole.
Simplify part to re-connect everything and your done.
Apologies for the imperfections of this model. It was only created to demonstrate this process without publishing images of what I'm working on.
