Hey
I want to create a band, that has the same thing printed on it, like The amazon packaging tape for example. After some playing around i thought i was where i wanted to be, just to realize the objects on the bottom are mirrored.
This is what i want to be arranged around the curve:
It sure has something to do with the points, where the curve goes “negative” to close the loop. But how can I avoid this? Flow along surface might be the alterative, but i also would want it to work that way…
Like I wrote, I wanted to get behind what the reason for the issue is. I like to know the roots of the issue and how the software “ticks” in order to solve similar issues later on
If something behaves (in my eyes) weird i need know if its my own fault or a bug.
But yes, flow along surface would have been the easier way from the beginning
fast and dirty without claiming this is valid for a scientific paper:
Flow based on curves - will not have enough information to define a unique and human expected transformation in space for all constellations: As soon as a curve has 0 curvature / is straight there is only a tangent, but not a frame / normal. Though the spacial orientation is estimated by (suspected / guess) World Z-Axis - and this might not correspond to our human expectations.
There are other command that suffer from this limitation - check _orient with a 180-degree turn.
it s not how the software ticks but more that a cross product can be a tiny or zero-length vector - and cad is always some juggling of tolerances… which might fail close to 180 degree here.
a surface without collapsed edges will have a proper curvature / normal definition at all positions. thats why flowAlongSrf wins here.
