Help For Surface Modeling

[FreeCutter]

Got the same messages in Report View also with 0.19 (?).

Once one of the coordinates is changed in the model, e.g. in Group_mo, Vertex008 the X is changed from 20.00mm to 30.00mm, what need to be done to update the model (recompute)?

Of course, "CurvesWB" is installed via Addon-Manager

Recently, there has been a big change in the file structure of the workbench.
That makes it incompatible with previous files.
Hammax has an old 32-bit Windows OS, so he has to stick to an older version of the workbench.
This is why, his files won't work on your FC 0.19
Below is file that should work fine.
