Hello - we are using a digital templating laser to apply the shape of the wall in which the plastic laminate countertop will be fitting.  Our process is to template the wall, bring in the .dwg into Microvellum/AutoCAD.  The curvature of the wall is brought in as a spline.  We then use PEDIT to change the spline to a polyline.  Polylines are joined using the JOIN command.  Our challenge is finding the widest extents of the polyline so that the Microvellum countertop product is large enough to capture the shape of the wall.  Currently, I am having to pan through the entire shape of the line to find the widest extents.  Is there a command or way to find the widest extents of a spline or joined poiyline?  Here is a video showing what I am having to do.  Thank you.
