Modify and improve the crayon SVG export plugin and DXF export plugin.

The crayon-to-SVG export tool has some issues. It contains many overlapping lines, making it difficult to color and modify. Could this tool be improved? I typically use it to generate construction drawings, which are vector-based. The software's DXF plugin is not very user-friendly, as it exports all the edges of your model, which are redundant and cumbersome in CAD. If possible, I hope both plugins could be improved. I believe more people in the architecture industry would benefit from this. Thank you.
