I am playing around with threads and screws, but I am beyond frustrated with something I have been able to do in the past, but not today apparently.
I have created a plane tangent to the surface of a cylinder, and I want to cut a closed profile away from the rounded surface, along a helix. I am making a screw here. For some reason, Solidworks does not believe that I have a closed profile. Any suggestions?
By the way, while playing with it earlier, I was able to do it on this same sketch. I was originally extruding off of the surface, but decided to mirror my sketch in order to cut away from the surface.
If I try to select the sketch profile line by line, I can select all entities except for the arc.
Why?
In the real world - wouldn't you set the cutting tool on the XZ plane of the lathe?
In the real world wouldn't you set up your cutting tool off of the end of the part - or would you start plunged deep into the part?
Do you have an image of something similar to what you are attempting to model?
What thread specification uses a 45° profile?
Wouldn't it make logical sense to have the cutting profile at the start angle of the Helix?
Is there a logical reason that you have two arcs overtop of each other at the point of the cutting tool?
What happens if you change one of the arcs to Construction?
What is the purpose of the extraneous sketches? (see attached)
