DimensionXXX has invalid 2D References

[stefano1]

Hi!

v. 0.19: my project uses few spreadsheets and sketches/bodies (furniture panels). everything seems consistent but the report view prints a long list of "DimensionXXX has invalid 2D References". Google can't help. Does anybody know what it means?

Thanks!

You have some over constraint elements in sketch, check out Solver messages

If andergrin's suggestion doesn't help, upload the file.

[stefano1]

ok, I will triple-check all the sketches then.
in the meantime..which is the exact dimension in which sketch, that matches "dimensionXXX"?

this is an output:
[...]
Dimension096 has invalid 2D References
Dimension097 has invalid 2D References
Dimension022 has invalid 2D References
Dimension026 has invalid 2D References
Dimension029 has invalid 2D References

Please provide a file and your FreeCAD version info as per IMPORTANT link above.

I think it is more than just overconstraints. We have seen something similar with references via expressions, where the object got lost. I guess you still use 0.18 (you didn't add your FreeCAD info ), so I recommend to switch to 0.19. It has improved error and solver messages.

Have you used Draft WB dimensions in your file? Have you got a spreadsheet cell with an alias that contains a space, if so they will fail in an Expression.

no draft WB, and the spreadsheets look ok - double-checked.
I noticed that 2 of my bodies miss their origin, and that is a red-alert in the report view. unfortunately I have no clue, how to reactivate it. any help?

uploading here my file would require a bit of cleanup so I guess I'm better fix all the issues like this "origin" stuff, before.

Well, after a backup, I removed the bodies without origin from the project, plus some outdated techdraws and everything is OK now.
About the missed origins: is there a way to manage it, without redraw everything?
Thanks!

Bodies can not have no axis system/origin, if they do then something is corrupted. I know this can happen if you drag and drop something in some circumstances in the treeview.

I think you will find that if you just create a new Body first, then right click on the components of the older corrupt body and select "move to another body", I think that will result in a new non-corrupt body. You may have to check that the attachments of the objects in the new body are set correctly.
