Yes I think so delete every components is the better thing to do.

Yes 232 000 instances of components2#, normal it crashs..

In short: To model effectively

Ok and what do you mean by “model effectively” ? Using groups, components,... ?

Hello,

I’ve made an heavy sketchup model (37Mo !). It is made of thousands of components (the components have a simple shape) that create a texture, that’s why it is so heavy So when I put the file on lumion, it doesn’t work. Does somebody know a solution to lighten the file without delete the components ?

Thank you
