Hi,

I have a complex object imported with a lot of inner geometry, of course as always object is not solid. It tooks 4M memory in file and CPU time to manipulate.

But all I need is only outer dimensions, simplified surfaces, 3D silhouette without all this inner geometry.

I tried solid tools but there is a problem with "not solid". I tried to find all these gaps but it is not so easy. Deleting lines, etc. time consuming.

Is there any plugin to do this job?

Thanks!

maybe this one can help you

but you will probably have to explode everything before using it
