In a moment you will see that I am new to Rhino.
I am trying to scale the object in the attached image so that it is 2mm larger around the perimeter. Once scaled, I would then like to Make a Hole using the object that is 5mm deep. I am not having any issues with MakeHole command.
The end goal is to 3D print or CNC the part to create a mold for pouring liquid silicone rubber into a cavity that is 2mm larger than the object shown.
When using the scale command, I cannot achieve the desired results.
Would the correct method be changing the width of the polyline, rather than scaling?
