multiple draft

[dgowans]

Is there a way that I can add multiple draft angles to an extruded feature at the time of the extrude (not using additional draft features)?

Picture an extruded square profile with 5 degrees of draft on 3 sides and 1 degree on the fourth. I'd like to be able to do this in the extrude feature itself, because the feature in question gets mirrored later in the feature tree. I know I could mirror faces, but I'm modifying an existing part and modifying the mirror feature in this manner will cause me headaches later on.

Any thoughts?

Thanks,

When extruding you can only define one draft angle. What you could do is define the 1 degree of draft in the extrude, Then use the draft tool to define the 5 degrees of draft on the remainig three sides. Doing this takes two features to do but I don't see any problem in doing it this way. However, it would be nice to see multiple draft angles in the feature itself. Maybe this will be available in 2006.

You can also include the extruede and draft features together in one mirror feature. It should not be necessary to mirror individual faces.

I imagine by now you have either tried and succeded (or failed) to mirror the extrude plus draft features. What's up?

What I ended up doing is applying draft after the mirror features.

Admittedly not the best modeling practice, but I've got a model to finish. The area in question is a vertical shutoff of an injection molded part (3 shutoff surfaces, 1 surface which needs nominal draft), which was the source of my original question.

Some of the downstream features (fillets, draft, etc.) made it necessary for me to make the change in this manner so I didn't cause chaos with the rest of the feature tree.

Thanks for the suggestions,

I would use the draft feature to define the individual drafted surfaces. You might have to split the surfaces. I just split a square and added the draft feature to the bottom half and top half.

Do you trust your intuition or go with the flow?
