@ Sswift: Thank you very much, you summed up all answers to my questions. I find the last tip worth to be trying to (overdraw). Your answer should be put in a blitz "user FAQ"...it's very important to know this :)
# Ban300: I use a similair system:
answer = ifEntityIsInLibray(whichEntityFileName$)
if answer = true m\mesh=loadMesh(whichEntityFilename$)
else m\mesh = copyEntityFunction(whichEntityFileName$)
Basicly I use a "library" and I copy the entity (pointer) to the meshEntity\entity type.
