I don't understand the logic behind data overwriting issues.
If I have two 3D models and want to create a new 3D model in one, then a question comes up whether I should replace the existing one. If, on the other hand, I only have one 3D model and calculate a new model, there is no query at all !?
I have overwritten a lot of data with it in the last versions because I forgot to turn ortho photos active off, today I overwritten a complete 3D model with a computing time of several hours.
I ask once again, politely and urgently, to always provide an overwrite of any data with a query as to whether I really want it.
