Problem in Geometry

Hi, i have created 10 parametric curve that intersect my cylinder creating points to use as discrete mass-spring system to model metamaterials. it seems like that 4 points cannot be generate since they are parallel to the edges in the x,y. i attach screenshot for understanding. Also,i would to know if there is a easier way to create this points since i have to create an array of them along the surface. (i have use convert to surface,parametric curve, partition object and convert to solid.) thanks in advance.

This is a bit strange, but assuming I understand your issue correctly: Probably the easiest fix is to simply rotate your cylinder by any amount that will let you avoid those problematic intersections, before you do the intersection with the curves. From your picture, it looks like your curves intersect every 18 deg. So, for example, rotate your cylinder 9 deg around its axis, and all 4 of your problematic intersections will disappear. Alternatively, you can always specify points of interest to you directly as geometric primitives, if you know their x,y,z coordinates.
