Hello :)

Does anyone know how I can equally divide a polyline into equal parts. I have a wiggly path that I applied a custom dashed line type to and would basically like to expand that so I can adjust it slightly and create paths for machining with. So either how you expand a line type to be a physical object or how to divide a freeform polyline into segments?

 

Thanks in advance

The following script will be a start. It will place a locus point at each point along a poly line. You can then use the split tool to divide the poly.

	R1,R2:Real;
	B1:Boolean;
Begin
	N1:=IntDialog('Number of Segments to Create:','3');
	H1:=FSActlayer;
	R1:=HPerimN(H1);
	R2:=R1/N1;
	For N2:=1 to N1-1 do
		Begin
			B1:=PointAlongPoly(H1,N2*R2,V1,V2);
			Locus(V1.X,V1.Y);
		End;
End;

Run(MarkPolyDivisions);

a similar approach is to use the Duplicate Along Path command (edit menu) to place 2d or 3d loci on the path.   Choose the Number of duplicates option rather than the distance. Then apply the Split tool in Point mode at each locus.  total pain if many loci. 

 

Might be advantage  to group the loci right after creation so that they can be deleted or classed for visibility control as the drawing evolves.

Perfect, thank you both. I had been using the duplicate along path for rectangles, but then they don't follow the actual curvature of the line so these are great solutions.

 

Also happy for my first post and to have such quick and helpful responses - thanks 🙂

Welcome to the club. Ask again the next time you get stuck. We are a pretty friendly bunch here.  ;-)
