Rotating while extruding "twist/screw"
Rotating while extruding "twist/screw"
(OP)
Hi all, this is my first time posting on the forum. I have been using NX for about 4 years and came across a problem I cannot model.
To simplify the problem, I will use a block. I am trying to extrude the block along an axis that is in the center of the block, while having the block rotate about that axis 2 full rotations over 4 inches. So it would be one full rotation every 2 inches.
For the life of me, I cannot figure out how to rotate the block while extruding it. Please help!
Thanks you,
Brian

RE: Rotating while extruding "twist/screw"
Is, draw your profile/sketch and then create a 4 inch long Line normal to and centered on your profile/sketch, to represent the axis of your 'twisted-soild' that you want as a result. Now select Insert -> Sweep -> Swept... and select the 4 inch long Line as your single Guide and the profile/sketch as your single Section, using for your Orientation Method a Rational Law suing the Linear Law Type setting the Start and End Values to 0 and 720 and hit OK. Your result should look like the attached image.

Some of the edges don't quite line up. Is the axis not in the center of the block or is something else going on there?

Have a great week!

RE: Rotating while extruding "twist/screw"
I do have an additional question. I got it to rotate and am playing with all the preferences, but can't get it to rotate the opposite direction. Any help would be great.
Thanks!

Let's hope so!
The first round of customer beta-testing of NX 6 started this morning and will continue for the next several weeks.

Just use 0 to -720 degrees for your Angular Law.
