My model is around 1000m x 1000m x 500m containing 175 bodies (including 3d terrain and buildings). When I use Boolean, it pop out this error "Model size is out of range" and there are also some buildings with error "Conversion of body to DesignModeler format failed". But those buildings have very simple geometry (e.g. only a simple cube). How can I successfully use Boolean and get rid of these problems?
