I thought if anyone could let a thread go through equally that I was glad, and made it with a laser cutting machine.
Step 1: Create the data
The point of the data making...
When I process felt, limit width occurs around 1.5mm(In the case of felt of 2mm).
So, it is necessary to offset a pass 0.75mm beforehand.
I make a dashed line from the pass which offset in the 0.5mm inside.
