I have a circular board which needs a cutout on its edge to clear the antenna of a radio module. My first thought was to manually draw the outline, tracing over the existing circle and adding the cutout, but the edge cut drawing tool is constrained to 45-degree angles - can this constraint be removed?
In some other PCB CAD systems, the outline is a polygon, and vertices can be added, removed, and dragged around freely just like KiCad does with zones.
Then I said, “OK, I’ll do the SVG-DXF thing”, but after converting an svg from my (reliable and units-respecting) mechanical CAD tool to dxf using an online converter, it imports at a miniscule size, regardless of units and import options. I don’t know if it’s a binary or ascii DXF.
A google search comes up with many, many instances of others struggling with this, and a zillion convoluted workarounds involving scripts, command-line incantations, and/or chains of open-source tools, some of them requiring OS patches to even install. I installed librecad but I don’t see anything when I import the svg.
At this point I’m considering just fabbing the board as a circle and cutting out the notch with a rotary tool.
It’s maddening that something so commonly needed should be so difficult.
