I know I've mentioned this before, but I do think it would be a great addition to the tool kit on RC:
The ability to re-join a polycurve that has been unjoined. This is especially useful when you have several long polycurves close to each other as you do in yacht design. Like this ...
There's one little tiddly thing that would make it absolutely perfect (for me that is ): re-joining an unjoined polyline/ploycurve. I'll start a new thread!
Eric added the "Zoom path width" function at your request. It is to do with zoom (magnification) not scale or resize.
Originally and correctly if you selected a line width (say 0.5 point) it stayed at that width whatever your zoom – so as you magnified the drawing it appeared to get ...
If I read your post correctly, you set up a drawing size of 10" x 8" and a paper size of 10" x 8" – all good!
But then instead of drawing within your "drawing size rectangle" you drew elsewhere – outside the drawing. This is like having your of paper all set up on your drawing board, but actually ...
With RC (and most other Mac based 2D CAD programs) you really do have to set your drawing size as a starting point. And draw at a scale so that everything will fit on the drawing. Otherwise you are going to get printing, scaling and zooming difficulties.
