Polyline end cap arc

[pcbzynr]

How do I create or rather edit polylines so that they end with a round instead of a butt end. ie. as if you had drawn a line with a fat ball-point pen. Is it possible to do this without adding a filled semi-circle to the ends of the line?
Thanks

It sounds like you are looking for a polyline "bulge"

I think the only way is to add an object...maybe a "donut" would be eeasier than a filled semicircle. If you use "lineweights" and a thick line it will appear with a rounded edge. And there may be a plot setting so polylines will plot with a rounded end - see "line end styles" in help.
