Modeling twist for rectangular section
Modeling twist for rectangular section
(OP)
I need suggestions on modeling a twist in a rectangular cross section.
The aluminum casting cross section is 160mm x 96mm x 10mm wall and the twist length is about 60mm. The twist angle is 12 degrees.

A helical guide curve couldn't hurt either.
RE: Modeling twist for rectangular section
But this what finally worked for me.
I created the 160x96 rectangular sketch and rotated the sketch in 3 degree increments with 15mm increments spacing up to 60 mm that resulted with the final 12 degrees. Than added "curve through reference points" on each corner of the incremental rotated sketch. Than swept the rectangle profile and a 60mm path with 4 guide curves.
The only inconvenience was that I now needed to array the feature 3 times at 120 degrees, but SW would not array the feature with guide curves.
The resulting part is a 3 bladed wind turbine rotor hub.

What about not merging the original blade to the base part (so you have two bodies) and doing a pattern of bodies instead of a pattern of features?
