how do you place threads on pre-made holes?

In SolidWorks help, look for Cosmetic Threads.

will this allow me to create the threads in a diamension rapid prototyper?

No. To make "true" screw threads, you will need to define the helical screw path, then extrude the thread profile along the path. Making true threads in solid models is complicated, time-consuming, and generates a LOT of data in the model that is mostly useless for most purposes, thus the "cosmetic thread" approach.

BTW, why not just make your rapid prototype model with holes, then tap them (or inversely, with "studs" and then pass a die over them) to form the threads. Saves a lot of time, and probably gives better results than a "bitmapped" thread surface.

I agree with btrueblood. That is the best way to do threads for printing.

What if that option is not available? Rapidprototyping threads works ok.

Solidworks needs to create a 3d thread function like the one in UG, works pretty good.

Anyone been able to make a thread library feature? I didn't have much luck last time I tried, seemed buggy trying to get the helix to add to the library.

I am trying to extrude the helix but when i select the helix it tells me to select a plain. what should i do

Whoops. Pardon my lack of SolidWorks grammar; I should have said make a "cut-sweep" with the helix as the path.

1. Make a helix, then create a work plane perpendicular to one endpoint of the helix (Insert>Reference Geometry>Plane and select the normal to curve radio button, then click on one end of helix).
2. On the new plane, sketch the thread section geometry, close the sketch
3. In browser, select the helix and the thread geometry sketch, select Insert>Cut>Sweep

Still think "printed" threads are a lousy idea, but then haven't seen whether the newer machines can give good enough surface finishes.

probably not, but i want to learn all post if it works thanks.
