I use extrusion objects a lot in creating my projects.

They do, however tend to fill up a lot of space in generated extrusion bodies/objects library. It makes the computer slow when wanting to create a new object or looking for existing ones. Sometimes I spend hours erasing lots of old 3D-objects already used -and saving those of later interest.

Is there an easier way to improve performance without the need to erase one single object after another? ...Appreciate all tips!
