When changing something in the geometry (like removing a line, copying a line or opening the datatable) you get the error:
[NL]: De rekenkundige bewerking heeft geresulteerd in een overloop.
[FR]: L’opération arithmétique a provoqué un dépassement de capacité.
Something is wrong with the geometry definition.
- You can try to eliminate the problem by simplifying the geometry. But this takes a lot of time and it is not a guaranteed success.
- Another thing you could try is exporting the model to dxf and then importing it again.
Yes, you will lose the cross-sections this way, but if you assigned Design Types well, it shouldn’t take that long to assign them again.
After each assignment, test if you can still edit the geometry without an error.
