::Reducing Large Files::

Hi all,
I have a Rhino file in size of about 1G, that I need to export to work with in Lumion8.
How can I reduce the file so I can export it in a lesser size?
I have tried the commands _Purge, Save as, and I don’t have any plugin installed.
Thanks all,

Have you tried save small? Failing that, to get to 1gb, you must have some pretty dense geometry in there. Can you post a screengrab with isocurves turned on? Have you used blocks where possible?

Yeah, I tried to save small, and save as geometry only, but it doesn’t reduce much. It’s actually an urban planning project of a neighborhood. I deleted many unimportant details but yet haven’t figured out how to export the file as a .dae file in a lesser size to work with in Lumion as I mentioned.

I’d try the following:
1, seldup and delete if you haven’t already
2, mesh everything before export. Join the resulting mesh’s by material to import into lumion
3. with the EXISTING meshes in your scene (assuming there are some, run the selmesh command to pick them out then hide everything else), try and reduce the density by running reducemesh command and see what you can get away with (60% reduction for example). Again, join meshes by material.

Export, and hopefully under the file size limit. You’ll need to run through this every time you export, so may be a pain… and save a copy of the file off before you convert to meshes etc. obviously.

Hi Elshar - if you have many repeated elements, as in an architectural scene with say many windows or fixtures that are all the same, using blocks can be a huge help in keeping file size down. Also consider using Worksessions to break up complex files into multiple parts.
