Hi Mike,
The rectangle used to trim the two swept surfaces can be any curve, either open or closed. The nice thing about blend surface is that it can take multiple edge selections, so where you cut isn't that important... it doesn't have to be a straight cut like shown in the video. If you have a file that you'd like an opinion on, you can send it to "tech(at)mcneel(dot)com".

but my circles are not always mirror of each other, i may one circles of different radius or even an ellipsie. In these cases, i would be hard to draw the rectangle.

good to know! cheers

Hi STU,
You can sometimes get the method you describe to work by leaving a space between the 3 blended srfs you'd create and using the Patch command to fill it. This is a tricky srf to join however with some shapes. Another approach would be to model a "hub" shape with trimmed holes in it and then blend your swept srf ends into that.

If you have a particular model in question you can always shoot it off to Tech(at)McNeel.com for suggestions. Just remember to "save small" and zip it first.

after playing around, am curious how you could branch 3 or 4 sweeps into on branch.

would you just mirror them radially around a center point and then blend all the side surfaces? any tips?
