Hi macray,

> For a while the work via separate files will have to make do.

Don't forget the display density adjustment too - that actually makes a pretty big difference to reduce RAM usage on heavier models.

Go to Options > View > Meshing parameters (the settings at the top), and set Mesh angle = 25 degrees, and uncheck "Add detail to inflections".

The display will look a bit more jaggedy but memory use will go down by a chunk.
