Making threads for a screw

andrew_jordan416

Hi all!

I am working with my PLTW IED students on creating parts for the miniature train project using OnShape due to remote learning (we use Inventor in the classroom). We've been following a tutorial for making threads for a screw and understand the concept, however, the helix still shows up after we complete the revolve to make the cut. Will this hamper our ability to actually make the part?

Thanks for your input!

Hi @andrew_jordan416

Nope it shouldn't be an issue! If you export the part to 3D print, for example, the helix curve won't be exported with it.

If you wanted, you could also delete the helix. Under the features list on the left, there will be a list of parts and curves in the part studio. The helix is a curve, so you can right click on it and choose delete. You could also hide it if you find it distracting. Sometimes it is useful to keep the helix so that you can use it for other features in Onshape.

Don't suppose the project is something you could share in the instructor discussion?

I can't post the project directly to the boards since PLTW is a bit particular about sharing their content, even older content such as this. However, if you are a PLTW instructor, I'd be glad to share it with you. With that said, the playlist that my students are using for guidance is:

The only issue that I had was that the instructor doesn't go over creating the threads on this particular part.
