Polyline segments as a list


Recommended Posts

Hello there!

Is there any node (or easy way) that returns segments (parts) of polyline from polyline? I mean the situation where a polyline is constructed as a mix of straight segments and arcs. Picture as an example.

 

I know I can get Edges from "Get 2D Edge" node, but this returns only start-end points, not the actual segment and it fails with arcs.

I am far better in Vectorscript than in Marionette, but I think you will have to roll your own solution.

 

Get Vertex will get you the location of each vertex.

Is Vertex Type can be used to determine if the vertex is of a certain type

Get Arc Vertex Radius will tell you the radius if the vertex is an arc vertex.

 

For Bezier, Cubic and Radius type vertices you will need to get the vertices before and after as well as the specific vertex to determine the segment.

 

In a script I would just walk the poly and make an array with the location, type and radius (if appropriate) of each vertex. I would then use those locations to create new segments using the two or three vertices that define each segment.

 

In Marionette I would guess that you will have to use some kind of list processing to do the same thing.

 

Good luck. Ask again if you need more help.
