This did my head in – HELP!!!
Hi All,
Having a major problem with what seems a simple thing: Sweep a rectangle along a linear path to create a frame – legs for an arm chair.Sounds like it is so simple, I could ask my cat to do it, while I watch the TV – well, it is not (at least for my cat, or me for that matter).
Here’s the link to the explanation, screen shots and a bonus link to the c4d file.

hope you can help.
TIA

I opened up your file and noticed that the orientation of the path spline was not +Z. This may be the problem, as the rectangle flips on the wrong axis as it negotiates the corner. See the fix .c4d file at http://www.birdhausdesign.com/public/

If you raise the maximum length setting of the spline that you are sweeping along. This may help.

Thank you good people!
Bear – looks like there are several overlapping polys in the corners in your file. The shape is fine – thanks, but the geometry is “un-clean”.
jimzepellin – I must say I am not aware of the setting you mentioned.
However I found a strange solution, I don’t understand it, but hey, after all I don’t have to, do I?
“Round” the path with more than 6 (original) points seems to work when the path is rounded with 11 or 16 points – strange indeed.
I must say that after 6 years of using c4d, this one really stumps me. I see no logic in the behaviour, and from where I seat, I’d be tempted to use the word bug. At the end of a day, what could be easier than sweeping a rectangle along a path?
Thanks again, more words of wisdom are welcome.

OK, it’s official, reading help helps.
“A common mistake when using rail splines is to use a path spline with adaptive interpolation. This can generate insufficient subdivision for the rail to work properly
