Taper

Taper

(OP)
UG18   I'm trying to add taper from a point.On a simple level,I'd like to take a four inch square cube and have it tapered from the center on up.(upper 2 inches of the cube tapered and the lower 2 inches remain straight)Sounds simple enough,but I can't get it to work.Thanks in advance

RE: Taper

I don't think using the taper command on your model as is will get what you want. There are, however, numerous ways to get what you want. The bottom line is, you are going to need 2 faces so you can taper the one you want and leave the other one alone.

3 ways (that I can think of off hand) to get 2 faces: 1) build the block in 2 phases, build the part you want to taper, taper it, then build the other half and unite it together 2) use the split face command to split your existing face into 2 parts and taper the half you want 3) build a trim tool in the desired position and trim your existing solid.

Which should you use? that depends on what other features this part requires and your modeling preference. If tapering the face is the last thing to do, splitting the face is probably the easiest way to go. I prefer not to split a face if there are a lot of features to add that will/may become child features of the split face. This just makes editing easier if the split face is no longer needed in a later revision (which I have seen happen often enough). In this case I would probably build some sort of trim tool.

RE: Taper

Taper is always applied to the whole face.

The chamfer tool is an option if you don't want to split the faces.

FYI - Pro/E Wildfire reacts the same way as UG.

RE: Taper

Maybe irrelevant, but I believe NX2 has a new feature called Split Line taper, that should do exactly what you describe... anyone know if it works that way, or if it works at all?

RE: Taper

Split line taper is another option, I think it came about in version 17 (or maybe 16). This feature would combine the 2 steps of splitting the face and tapering.

I have used this feature a few times and it works as advertised.

RE: Taper

If you go to feature operation simplify, imprint faces.
set up a datum plane and you can imprint a line where you want the taper to start.
