I am new to Rhino. I am trying to draw a poly line. When I left click and draw a polyline, once completed I right click. If I click on that line only one segment is highlighted as if I have drawn a line with segments. I have tried drawing a polyline by right clicking the icon but get the same results. I have also tried joining the polyline but unable to join.
I cant figure out what you are doing wrong. But it sounds like you are making the command lines instead of polylines.
But a quick work around might be to write polyline in the command instead of clicking.
Hello - is your selection filter set to select sub-objects?
