Twisted strip

[sweetluge]

How would I go about making a simple rectangular strip that twists one time so that each end is in the same position, but one end has been rotated 180 degrees? I'm assuming I'll have to use the bezier curve plugin?

The FFD plugin might do it for you see the video in this post

If you want something like this, I added a tutorial here .

There isnt really an easy way to do this, as far as i know.

1. draw a rectangle and rotate the top about its center by a number of degrees thats a divisable of 180 (180/10= 18 sections to twist)

2)Make that rectangle a component and move move it up and rotate it. Do this untill youve got your shape.

3)explode all the components and soften all the edges.

Yeah, this is a better way than mine since you need not hassle with the vertex merging (and still remains accurate).

Thanks Remus!

As bob mentioned, you cna also do it using FFD, this is a really quick try:

Things to note:
youve got to subdivide the face of the main recatngle before you start
Its tricky to do it accurately
You can get some pretty weird geometry (i deleted some stuff that went weird.)

thanks for all the help! I think a found a way that suits my needs. I used Bezier curves to connect two perpendicular intersecting rectangles and then used curve-stitcher to create the strip. Pretty quick, if not perfectly accurate

I used a method similar to Remus but with ctrl+erase between steps so that clean up is quicker and easier.

Have a look at the attached file.
