I have an editable poly object with a loop of edges selected.  I’m trying to set it’s length to a new value, scaling the edges around a point.  Does anyone have any suggestions on how to do this?

This code will select the loop and then return it’s current length, but I’m not sure how to go about scaling it to match a specified value.

fn SelectLoop obj =
 (
 obj.buttonOp #SelectEdgeLoop
 baSel = obj.GetSelection #Edge
 total = 0.0
 edgeCount = obj.GetNumEdges()
 for i = 1 to edgeCount do
 (
 if baSel[i] == true then
 (
 vert1 = obj.GetVertex(obj.GetEdgeVertex i 1)
 vert2 = obj.GetVertex(obj.GetEdgeVertex i 2)
 total += distance vert1 vert2
 )
 )
 print (units.formatValue total) as string
 )

I don’t think that will work. Your “length” is a sum of distances - a derived value - the only way to change the “length” would be to move the attached vertices which will, in turn, affect the length.

Yes, that’s essentially what I’m trying to do.  Scale the edges up or down by a value to make them total a specific length.
