How do I create a real (not cosmetic) 3D screw/hole thread?

How do I create a real (not cosmetic) 3D screw/hole thread?

How do I create a real (not cosmetic) 3D screw/hole thread?

(OP)
There were LISP programs in AutoCad that did this.  Is there a way to incorporate this in SolidWorks?

RE: How do I create a real (not cosmetic) 3D screw/hole thread?

Check the help for "helix".  However, helices are very resource intensive.  You probably don't want to put many helices into an assembly, as you performance will really go down the tubes.

RE: How do I create a real (not cosmetic) 3D screw/hole thread?

Create the hole.
Create a helix on the surface of the hole.
Create a plane at the end of the helix.
Sketch the thread profile (removed portion) on the plane.
Use the Swept Cut tool to create the thread.

Ask yourself why you want to do this.  As was mentioned, helix geometry is resource intenive: it eally slows things down.

f you need the geometry for creating tools for casting or molding, then go ahead.  If not, best to stick with cosmetic threads.

All it is a Cut-Sweep with a profile and a path (helx) it will cost you performance and can slow you down in your assemblies, etc. but i know some people have to have them. SO when your system gets slow, you can't complain, because you have been warened that helixs and complex geometry will slow systems downs. SW is not AutoCAD, SW requires highend machines where ACAD didn't need this... so hopefully your system is configured correctly to run with SW, or you will take a larger hit then you would if you where running certified equipment.

The methods suggested by the Limey and Scott are how I've done it in the past. You should be alright if you are modeling single-component parts or small assemblies, but be sure to heed the warnings about futzing with larger assemblies.
