If you come across this problem, here is a simple solution:
In GstarCAD in Settings of GeoWin DTM switch off the monitor of objects. This was added to Settings in the last version 2022125.
In AutoCAD, BricsCAD and GstarCAD set the system variable "selectpreview" to 0 (in BricsCAD you also need to turn off the Quad).
BricsCAD - connecting to WMS
In the first step we choose the coordinate system ( command _GEOGRAPHICLOCATION )
Problems installing GeoWin
At first, it is good to make sure you have the right version of GeoWin and 32bit GeoWin for 32bit CAD or 64bit GeoWin for 64bit CAD.
