I have worked for many years in the simulation industry and worked with MultiGen Creator. This 3D modeling tool had a very nice option called “Isolate select”. If you are working on a complex model or scenery and having difficulty with speed or parts that are blocking your view when going around it than this option is very useful.
Just select the part you need to work on and type “I” and a new workspace opens, it is also possible to switch between the two workspaces.
