Hi Sebastian,

To split it up into smaller files, try selecting some objects (like maybe just half is fine) and then write only those objects to a new file using File > Export. Then don't delete them since that will create a huge undo unit - instead use Select > Invert to flip the selection around and then do another export.

That should help to break the file down into 2 separate files.

Yeah all kinds of actions require allocating some memory at least for a while to do stuff, so everything will start to fail if it reaches the "memory totally full" type state - you want to try to never reach that point.

Nope, the export mesh is calculated totally separately from the display mesh, so the display mesh setting has nothing to do with the export.

Hi Sebastian,

Yeah 0.2 is extremely tight - that's asking for only a deviation of 0.2 angular degrees between surface normals of the display mesh, so that's going to generate a tremendous number of triangles.

Even 5 degrees is still quite tight - the default is 10 and even that is on the tighter side.

If you are working with large files I would recommend setting "Mesh angle" to 25 degrees (25, not 2.5) and uncheck "Add detail to inflections" and that will help lessen the memory load by quite a bit.

Thanks for the replies, everyone. Like I said, I got it sorted and learned something too :)
