Error when importing dxf

[FlorianSan]

Hi,
I have a problem importing a set of dxf, I don't understand why?

What is the procedure to know the elements that cause problems?

Thanks

Yeah, it's not exactly helpful here. Problem invariably is because your objects aren't properly closed. Opening the first couple (using https://sharecad.org/viewer) you have included numbers in the middle of your parts; that's not going to be a valid closed shape.

Yes, I understand completely, but the number in the centre and the lines that make the shape not closed are on another layer. Would it be possible to nest only on a layer that is a closed part and apply the other layers afterwards?

I think that would be a great idea. We also hava parts with engraved bending lines, naming, charge numbers ect.

If cut layer could be set, and all other layers is just passed "as is". it would be a great feature

Make the numbers a valid shape (with some volume). You have to highlight them anyhow to engraver instead of cut, no?
