Turning DXF into an SVG in rust.

[raisfeld-ori]

Hi! I need to turn a ".dxf" file into a ".svg" file in rust. I originally thought I would just need to convert every entity type into an equivalent svg object. I made this package that way, but it failed for a lot of layers and the colors weren't working properly. This package worked amazingly for me but I couldn't tell where the conversion of SVG to DXF happens...

I would be happy if someone were to tell me how does dxf-to-svg conversions happen in this codebase, thanks!

By the drawing add-on:

that doesn't really help out... I already looked at the file, but I can't tell what am I doing wrong compared to this package

The rough workflow of the drawing add-on:

Frontend:

• resolving the DXF attributes in the context of the layout, block or viewport
• ordering entities and filtering invisible entities
• preparing the entities for the render pipeline

Render Pipeline:

• convert DXF entities (incl. text entities) to drawing primitives: lines, linear paths and filled paths
• clipping drawing primitives (viewports, clipped block references)
• resolving line types into solid line segments
• passing the drawing primitives to the Backend

Backend:

• renders the drawing primitives as SVG, PDF, PNG, JPG, HPGL2, ....
