I just starting to learn how to script, i think i’ve gotten as far as i can go on this with a little help from chatgpt. So far i’m getting a selection then splitting it with another selected curve. Id like help figuring out how to move part of my selection after its been split based off of the curve that was used to get the split points and its orientation.
If you collect the return values of SplitCurve, you can sort the other components into two groups based on which partial perimeter curve they’re closest to. For the move direction, you can define a plane based on the seam line start and end points and get a perpendicular vector that way.
start = rs.CurveStartPoint(flat_seam_line)
end = rs.CurveEndPoint(flat_seam_line)
plane = rs.PlaneFromPoints(start, end, start + rs.WorldXYPlane().ZAxis)
distance = 10
move_vector = distance*plane.ZAxis
Thanks ill give it a try.
How would you filter through the return values of rs.SplitCurve to determine which side of the plane they are on.
When you split your boundary curve, rs.SplitCurve returns a list of the pieces. You can use CurveClosestObject with each of the other curves like this:
perimeter_curve = # whatever
other_curves = # whatever
split_pieces = rs.SplitCurve(perimeter_curve, splitting_curve)
side1, side2 = split_pieces
side1_pieces = []
side2_pieces = []
for curve in other_curves:
id = rs.CurveClosestObject(curve, split_pieces)[0]
if id == side1:
side1_pieces.append(curve)
else: # id == side2
side2_pieces.append(curve)
rs.MoveObjects([side1] + side1_pieces, move_vector)
Thank you for the help, ive got it to move one line of the split curve but the other curves are staying stationary. I hope implemented this correctly
