Have had the problem to nest many objects on 4 sheets.
In the build-in nesting function (web-version of deepnestio) there is just the possibility of one sheet.
The offline-version of deepnestIO cannot read the .dxf or .svg without errors (.svg will result in misplaced objects (e.g. a hole is outside of the part).
The only workflow with success was:
- export the objects with the 4 sheets as a .dxf from lightburn
-import this .dxf in Fusion360 and reexport it without changes - the reexported .dxf is then able to be processed in offline - DeepnestIO
