I can't get the external thread function to work properly

brian_gifford

Hi.
I am very new to Onshape, and I am slowly finding my way round. I have tried to use the external thread function, and although I can do that without any errors coming up, the thread portion still shows as a smooth cylinder in onshape, and likewise if I export to my slicer as an STL.
I'm sure I am doing something stupid, but I would be very grateful if anyone can help me. I am trying to generate metric threads.

Thank you.

The "standard" thread feature is only for creating "schematic" thread to show on drawings. If you want to 3D print a thread I would recommend using the "threadlabs" feature:

I have a question about this feature.

Im trying to make a 1/4-20 as shown in the picture, but this program did not let me type 1/4( it goes to 0.005 and shown as 5/16)
How could I make it the screw?
If you have the new version, please update for me(or everyone)

I can't make 1/4 - 20 because it automatically goes 0.05( shown as 5/16). How could I make it right?

If you want a 3D model from McMaster, why not just download the CAD model and import it into Onshape?

I'm with S1mon.
Also why are you trying to give a diameter value for pitch? The cylinder modeled for threading should be 1/4" and the pitch for thread tool should be 20.

Wohooo Im new to onshape and I didn't understand what this meant, it looked like greek to me when I opened the link, then I watched this YouTube video (https://www.youtube.com/watch?v=-tsY_TjWapU) and discovered custom features in Onshape. This incredibly powerful tool just got many times more powerful. I'm in heaven Thank you everyone
