My model consists of:
Command: Show
Showing 415 hidden objects.
Command: SelBadObjects
24 curves added to selection.
Command: SelAll
643 block instances, 9 extrusions, 230 hatches, 230 points, 616970 curves, 8 polysurfaces, 869 surfaces, 8 meshes, 1 annotation leader, 10 linear dimensions, 604 text added to selection.
When I open it in Rhino 5 it takes about 20 seconds to complete where as in WIP it’s more like 6 minutes.
The majority of the contents are imported DWG files hence the blocks etc. When I strip these layers out the so that there is only the Rhino generated Polysurface then File opens in 2 seconds.
If any one at McNeel would like the file for further exploration I can upload it via the ftp link.
On a minor note both Rhino 5 and WIP state that 26 bad objects were created on opening but I can only select 24 curves.
26 bad objects were created while reading "J:\Jobs\J10507\Calcs\Rhino\J10507_3D_Model_20150813.3dm"
File “J:\Jobs\J10507\Calcs\Rhino\J10507_3D_Model_20150813.3dm” successfully read
Command: SelBadObjects
24 curves added to selection.
Why the disparity?
