Hello @thinzar is it something here you mean ?
I’m working on a concave curve roof as shown orange color line and having some difficulty placing 400mm width lines on the surface. Could you kindly guide me through the process? thanks sir.

Hi Sir…The roof is a slanted curve, so when I project lines (spaced 400mm apart) onto the slanted surface along the Z-axis direction, the resulting spacing between the projected lines varies, showing values like 404mm, 403mm, and so on, as shown in the snapshot. How can I maintain a consistent 400mm spacing between the lines?
Hello hard to say as i dont can see whats goin on. but in my example i dont use closest point to…so not sure
thanks sir…if “closest point to” won’t give the correct spacing, is there any better way to divide slanted curve surface with U and V values?
yeah have you tried what i show ? and doesnt that work ?
@thinzar - which Dynamo build are you in?
i can not see your screenshot fully. that’s why i tried other way. sorry sir
