I’m systematically trying everything I can think of to get my DXF export from Inventor into Kicad (both version 5 and 6) and onto correct layers. NOTHING has worked correctly so far.
Origin: Internal wafer for rotary switch, designed in Inventor, each sketch exported as DXF, which is the only native option. Individual files exported for edge cuts, solder mask, F.cu and user dwg (to assist in lining everything up). I’ve seen some plugins to export to SVG, but haven’t tried those…yet.
These exported sketches need to import into Kicad and be assigned as copper, mask, edge cuts etc. I’ve accomplished the edge cuts. I’ve accomplished the mask. I created a footprint built from imported DXF files. But for the life of me I can not convert the DXF into usable top copper polygons.
I’ve watched tutorials. I read blogs. I followed along step by step with the skull and crossbones video. Great BTW! I’ve tried converting my Inventor DXF export to every format my software will generate. So far:
Inkscape: DXF to SVG, BMP, PNG SVG toShenzhen
Corel: BMP, SVG, PNG filled, not filled, no line weight
Online converters: DXF to SVG, BMP, PNG, DWG
FeeCAD: import DXF. Stepup to Kicad, export CAD file
There seems to be a general incompatibility between 3D CAD software,vector based graphics software and PCB CAD software. I’ve spent hours “cleaning up” DXF files and converting to vector based file types. Corner nodes are ALWAYS just slightly not connected. Most bitmaps translate into pixelated garbage. The online converter does a great job at conversion, but skews the scale to 10:1. UGH!
I’m more than willing to put in the work, but feeling like I’ve hit a brick wall. Am I so daft that I’m missing some obvious step in the workflow?
What I need to accomplish: a custom shaped pcb that replaces a layer on a rotary switch, with custom shaped pads in a 300 degree array (make before break). This requires closely placed pads with clearance overrides.
What tools I have available:
Autodesk Inventor 2016
Autodesk Fusion 360
Inkscape with SVGtoShenzeng
FreeCAD with StepUP
Thanks for any insight.
