Is there any option to remove the cosmetic feature line in the slot of a slotted set screw in Creo 2.0 (refer attached image)?
I tried using edge display but it's not working.
I find the best way is to use layers, if the thread is contained in a preset layer, you can simply hide the layer and the thread will be removed.
Otherwise try creating a new layer, adding the thread feature and then turning it off:
Remember to save the layer status, to make sure it stays hidden for the next time you open the drawing.
Sorry, I misread your question. There is a way to do this, but it is not very elegant.
First, select the three surfaces of the slot, then copy&paste to create a Copy feature
Second, do the same with the surface of the cosmetic thread (make sure to select the geometry, not the feature itself) to create a second copy feature.
Third, create a trim feature, using the copied thread surface as the Trimmed Quilt, and the copied slot surface as the Timming object. You may have to use the arrows to flip the removal side, but that should give you what you need.
You can then hide the original thread, and you will see what you want. Basically, you won't be showing the actual thread on the drawing, but a copy which has been cut to suit the slot. It is a bit awkard, but it is the only way I know how to do this.
