I've programmed a sweet tool for converting DXF/DWG files into SVG - this works already. The target of this project is to create a SVG clipping from that AutoCAD file.
Here is an example of the generated svg-file:
<svg width="231" height="586" viewBox="-1843.4575 -2473.4065 628 1588" version="1.1" xmlns="http://www.w3.org/2000/svg" style="stroke-linecap:round;stroke-linejoin:round;fill:none">
<g transform="scale(1,-1)">

</svg>In every viewer it looks perfect. But not when i try to clip it.
I've reckon that it should't contain more than one MoveTo command, is that right?
Is it maybe because the coordinates are absolute?
I've tried to remove the M commands with no affect. Also merged it into one Path with an "Z" close path at the end.
Would be niceif anyone has a solution.
Kind Regards
I figured it out by myself!
What I've done is:
1) Read all paths
2) Order them by "move to" and "end" points by matching coordinates. (if it is a curve, take care of the direction)
3) Remove "move to" statements except the first one
4) Merge all paths to one
5) Append "Z" at the end to close the path.
Additionally I've calculated all values into percent values.
The result is:
