creating contoured sweep round cylinder?

[proed]

View attachment 541


We need to remove material from a part - basically a stepped or contoured shape at the end of a cylinder... the shape should taper to a point in the centre of the cylinder.


I've tried variable section sweep / surfaces, etc.. no joy - any help welcome.

This can be done with surfaces. You might try breaking it down into 3 different cuts & then pattern.Here's how one might look. This was done with more quilts than I originally thought because your curves don't line up with the cylinder edge.

Ed,


Made something similar using patterned helical sweep protrusion. Create sweep profile on a plane (thru axis & angle) that you can pattern later. Adjusting dimensions should result in required shape.


Have a look!

mgnt8 - that looks promising.. I reckoned surfaces would be the way. What kind of surface is in your example? - variable section sweep ? Thanks for the response.


Brano - that may work, thanks.

proed - boundary blends, I just used your curves (and a few others I had to create)to create several surfaces, merged them until the area to be removed was enclosed by a watertight quilt, then Solidify/cut away. It was a roundabout way of doing it and I'm not sure how easy it would be to edit (probably not very) but it got the job done.
