Error while solving some dxf file's parts

[ziad-ashraf7]

i was trying to nest these parts on the Web tool

prob 1.json

and got this error message:

I think that the problem is with the parts has so many curves.

can you help me with this ?

Thanks for the report and the file, it helped a lot.

You were right, the problem came from the curves. In the circular arcs of your DXF parts, the start and end points are not exactly at the same distance from the arc's center (they differ by about 0.000002). That tiny difference was enough for the solver to think that two consecutive elements of the part crossed each other, so it rejected the part as an invalid shape. 12 of the 27 parts of your file were affected.

This is fixed in #710: the solver now recomputes the centers of the arcs from their endpoints before checking the shapes. With the fix, your file loads and all 27 parts are nested in one sheet.

The fix will be available on the web tool once the current deployment finishes.

One more thing: your parts allow mirroring, and while testing your file I found a separate bug with mirrored parts that have curves: the arcs of mirrored parts were written to the solution the wrong way round (the long way around the circle). This can make mirrored parts look wrong in the drawing of the solution, and can affect the reported dimensions. A fix for this is in progress.

Sorry for the late replay !
Thank you so much for your fix, I really appreciate your response and help.
I'll try it now without mirroring till the mirror fix is done.

Thank you again for your effort !

The mirroring bug has already been fixed

I see, what a nice work !
I think that I was late to ask so much :)

Thank you for informing me.
