Rubber Track Design

Trying to model a track but i have it in more of a triangular orientation then an ovel like this sample picture. Any advice on how to pattern the tread and inner lug around any shape i desire? I have tried making an extrusion on one of the flat faces and then patterning it around but it keeps the lug in the same orientation and does not follow the contour nicely. Any advice for me

I made this simple track with the emboss feature. First created a sketch with a pattern of the profile, dimensions linked to the geometry of the basic track to match the right size. Then emboss the sketch first on the straight part, then reused the sketch and emboss this on the curved part of the track with wrap to face option on. Last step, circular pattern the 2 embosses to the other sides. Check the attached ipt (2012) to see how i did it.

You can do rectangular pattern in part enviroment along choosen curve, and set orientation to direction1. This should work.

 

I hope that's what you're looking for.

Thank you for your replies! JDMather that does work to pattern around and i can get it to follow the contour i want but it leaves a gap between the "treads" as it is patterned around a curve. It does not keep tangent. Any solution to that?

I don't see a pattern in the file you attached?

 

When I attach my solution the sketch for the tread will be on the XY plane.

The extrusion for the belt will initially be a surface body and then Thicken after the Pattern of the treads.

That is why im on this forum, It will not allow me to pattern and keep tangency, It just gives an error. The lugs i want to pattern are in the file though.

I experimented with this one a bit more.

It is going to be a bit more work than I originally thought.

Because the tread cleats bend around the curves - my attempt would be with patterned-trimmed surfaces, thicken and trim again.
