Import PCB from KiCad, Polygon instead of round

Post by Andi1994 »

Hello,

I've been using FreeCad 0.18 since yesterday.
Now the following problem, so that I can continue working with the step file, which I create with FreeCAD, the angular curves must become really round.

Enclosed a picture

I'm hoping you can help me.

Grüßle

Andi

Without an actual file we can only guess if that is just a visual representation or it is imported that way. Also if this is 1mm or 1km radius...

In KiCAD it is perfectly round, I export it without detours directly into FreeCAD, but then it is displayed angular.
In a VRML file the curves look worse.

Since we work on a PCB we are in the range of mm .



I tried to upload the KiCad file, but this format is not supported.

What format specifically did you try to upload?

The step file contains 3 straight edges for that round. Maybe you have some setting in KiCAD exporter to convert arcs to edges on export?

So how can I edit this step file in FreeCAD 0.18?

So delete the angular curves and insert a quarter circle.

I have no idea what you want to do with that track so can not give meaningful answer. Please give more info.

I doubt.. kicad ATM doesn't support round traces

What is the need for this to be round rather than a line approximation in FreeCAD or step?

I'm curious about the use case?
