Measuring along perimeter made up of several edges

graham_lock

Hi,

Referencing the image below:

I have flat parts where the perimeters may be comprised of combinations of lines, arcs and splines.

Taking the image as an example, if I have one point on the perimeter, is there a way to create another point at a given distance along the perimeter from that first point?

Any help appreciated.

Thank you.

I found the easiest way to achieve this is to create a path around the edges and then set points along the path:

path = constructPath(context, qEdges);

pointLocationsArray = [positionsOnSide]; // 0-1

lines = evPathTangentLines(context,
  path,
  pointLocationsArray
  );

The end points are then found using:

lines.tangentLines[x].origin
