Hi all and thanks in advance for help !😀

Say that I am newbie and 70% illiterate on CAD 😑

For the purpose of milling two planks of wood into two shelves with curved profile, I drew two shapes using the Bezier tool.
Then I saved them in DXF format and...
- the "larger" of the two profles (filename "mother"), when "transformed" in DXF, is OK, no problems at corners and the woodmillingshop told me "ok we can do it". (I am annexing its svg and dxf)
- the "smaller one" (filename "daughter"), which is just derived from the "larger", looks 100% OK in svg form. But when I save it into DXF and visualize it, the two corners at the right side ar dislocated and it is not a millable polyline. With suitable enlargment, you will clearly see it.
Again I am annexing its svg and dxf files.

I am stuck up. If anyone can also help me professionaly, I accept proposals !
Side info:
- inkscape version is Inkscape 1.2.2 (732a01da63, 2022-12-09)
- I tried to use the two DXF formats available (xxx R12 and xxxx R14, but it does not solve the problem in "daughter")

Many thanks again, Alberto from Italy

The files have un-needed bits outside of the page and profile that I would remove. There are also numerous un-needed groupings that I would remove.

I would keep the the primary profile path, but remove any extra nodes and make it a single path, not multiple paths across groups.

Dear Tyler

Many thanks for prompt support !
here is the issue: I drew these profiles quite "naively". Somehow "mother" is OK, but "daughter" not.
I am not able to implement your kind suggestions, and I cannot ask anyone of you guys to teach me step by step from my low level, I guess !!
Any suggestion on how to find someone ("professionally") to solve the issue ? I tried Fiverr, but vey few people there seem to be familiar with inkscape...😐

Thanks again for your time !

Alberto

Mother is not ok, but may look like it.

Here's how I would revise Mother.

Here's how I'd revise Daughter:
