Hello!
I have tried to assign a stereographic coordinate system (epsg 31700) for a model data industry (waste water) and the model is now hardly opening after the command tbgenerategraphic (it takes 20 minutes to open a empty database).
On the other side if I set the coordinate system "none" the data will be open in less than 20 seconds, bun I can not edit anything.
Is there any solution for such a problem?
I have to mention that the coordinate system epsg 31700 is equivalent to epsg 3844 and it's a commonly use system for Romania, so it's preferred to be used in this model too.
