I'm modelling a backpack. And want to recreate a zipper. So i cannot iterate and object along a path (yellow dotted lines on secong image). I used array modeifier but it doesn't work. Please suggest me a tool to implement it. If somebody wants to open a file and to tinker, path along which object is iterated called "Path", and object called "Shape". Thanks!!!
Select the curve, ALT C to convert from mesh to curve, Ctrl A to apply rotation and scale, in edit mode select the first point of the curve, Shift S "cursor to selected", then in object mode set "Origin to 3D cursor" (in the T panel).
Select the shape mesh, Ctrl A Apply rotation and scale, Origin to 3D cursor, add an array modifier and then a curve modifier, choosing the curve as target.
I had to smooth the curve where it bends nearly 90 degrees.
