Randomize Scale & Rotation of an existing blocks based on their base points

[Rickson]

Probably best to use a script (Grasshopper would require replacing blocks or putting the rotation into a script that affects the block in Rhino)

Rotate blocks randomly around their basepoints

You need to indent the whole script under def test(): - the formatting on Pascal’s post went wrong, should look like this: import rhinoscriptsyntax as rs import random def test(): Ids = rs.GetObjects("Select block instances to rotate", filter = 4096, preselect=True) if Ids is None: return vec = rs.VectorCreate([0,0,1], [0,0,0]) for Id in Ids: pt = rs.BlockInstanceInsertPoint(Id) ang = random.randrange(-180, 180) rs.RotateObject(Id, pt,ang,vec…
