Rhino Twist Question

[mrplace]

I have read the help files in Rhino and done a search here and did not find a good answer.

I have been trying to figure the Twist function. I have only been able twist a 2D curve, and then only can get a 180 degree twist.

I want to take a 3D rectangle and twist it a full 360 degrees, or atleast play with some different looks anyway.

Could anyone point me in a direction to look for some good information on using this feature?

Thanks,

Extrude a square along a helicol curve the pitch and length you want.

OK! I just tried that and it's not so great an idea. ;-(

I made a square column marked a center point at top and bottom. I selected twist and followed the command line prompts. This is the result. First time I ever used that tool.

Gary that just goes to show you're a lot smarter that I am. I tried the same process, including the command line and got something that I wouldn't show! Actually it was real nice and I may carve one out of wood sometime just for one of those artsy projects!

Once you establish the axis, pull a line out to one side and spin it around like you would for a rotate. As with all things CAD, I can do it but trouble explaining it.

I can't even select a 3D object with this command active. Am I not holding my jaw right or something?

[duluthboat]

Select the object before you go to transform. It goes something like this. I have this object, I want to transform it, I want to twist it, this is the axis of the twist, this the reference angle from where the twist starts, this how far and the direction I want to twist it. That’s the way I step it thru. Oh, and I stand on one leg looking north. ;-)
