Do you want to see threads? I've not been able to accomplish that.

Hi yes all I wanted was to see threads

Yea I have never seen threads in my tapped holes in the simulation either... I don't really see the point of it, the developers apparently don't either.... It would look cool sure, but would it really add anything? It would also consume a large amount of extra computing power, especially when rotating the part, which would slow things down..... I think the cons outweigh the pros on this one. If it were added, I would definitely want the ability to turn it off...

I know that it would slow things down I was just curious

I guess it could be done...in theory. This assumes that you already have a cylinder cut in your solid that represents the minor diameter of your hole. It also assumes you have the Solid Modeling module. First, create a helix the major diameter using Function in your Curve Wizard - there is an example of how to do this in the Help file. Next, create a UCS on the end of the curve so that your thread profile is oriented to the helix properly. Draw a triangle (or whatever) that represents the profile of the thread you want to cut and chain it into a curve. Sweep that curve along the helix as a cut.

Will this actually work? Not sure. You don't have a lot of control over how a profile maintains its orientation to its path when you sweep in FC, so it could end up flopping around on you.

Like I said, "in theory." :shock:

The only time I ever see threads is in thread milling

This seems new to me the modelling thread and perhaps this could also not familiar to everybody. That is why many will be getting curious about it.

Maybe I'm missing something but I can't get enough control to create a surface or solid thread form shape in FC. The helix and the thread form geometry are not an issue, but when it comes to sweeping the form along the helix it doesn't stay perpendicular to the centerline.

I've been using FC for only 6 months and the geometry creation paradigm has yet to click in my brain, hope it happens soon!
