Is everything unioned and did you save in pieces or all at once? The cubes and triangles around the main door should convert to 12 and 8 polys respectively. If you save at high enough quality to make the archway look smooth you will end up with 100+ polygons in your cubes. I found out quickly never to group unless necessary. Rhino adds lots of mesh detail where surfaces meet and recurve. You can join after the nurbs are converted to meshes. You can also throw away the interior faces of the cubes, Any surface that won't show. You can pick an object type like the cubes and use the Polygon mesh from nurbs object in the tools command to individually control the number of facets in an object. With squares you can push the slider all the way down. Delete the original nurbs and render. If the quality is poor click undo twice and remesh at a higher setting. Your little mushrooms around the borders of the window eat a couple of hundred polys each and I count 196 of them in just the faces I can see. They could be a lower quality mesh whereas your front door arch has to look smooth. You might reduce them and also peel off the back faces. You could be able to get this down to a more reasonable 12 megs. Clearly however you are a modeling god. My largest work to date has been TMA1 from 2001. 120 megs in bryce. P.S. If you burn to a CD and send copies Renderosity Marketplace will sell them and ship through the mail. This avoids horrendous downloads and lost connections.
