Hi group / support I would like to create “loopy” lines (see image below) but i need to be able to create them easily as i want to change any vector profile I have designed into a loopy line profile, ideally i would like to select any 2d shape / curve / profile and then change it to the loopy vers…

Hi Tay thankyou for your reply, it sort of works but i guess i forgot to say i need it in 2d. A

I guess you just needs to flatten it

yes i thought that but the loops run around the curve in 3d so when looking in plan view in 2d they only look like zig-zags not loops.

Another way is to draw one piece and then array it on curves

yes this is possible but i want to keep it simple as i might use it alot and the 2d curves i want it to run round could be quite complex. I am hoping i can somehow create custom line types or similar then it is just a case of clicking a couple of buttons to convert.

Hi Adrian - [image] adrian: is this possible at all? We have a request for user-defined linetypes on the list as RH-29232 . I’ve added your vote. -wim

Hi Wim thankyou, i think it is a great feature that could be easily implemented into Rhino. Regards adrian

Hi Adrian - [image] adrian: […] that could be easily implemented into Rhino. We don’t mind you creating a plug-in that does this. -wim
