I am working a lot with large landscape files in Sketchup. With large I mean large as in some 800000 edges and 500000 faces. The size of the file discussed here is near 850 MB.
The problem I face is that panning and zooming in Sketchup is very slow under these circumstances, a fact I have - up to now - taken to be a direct consequence of size.
For the record, the file discussed contains a landscape divided into a large number of groups, this is very much intended.
Also, for the record, I use a GeForce GTX1080Ti graphic adapter.
In order to evaluate Blender 2.80 I exported the Sketchup file to .dae and imported this into the Blender environment. This experience with Blender vs Sketchup gave me several surprises:
Panning and zoooming in Sketchup for large files is a pain. Panning and zooming the same file in Blender is swift and instant, in fact, a pure delight. Please see the two videos attached.
The Sketchup file is some 839000 MB. The Blender file is only some 597000 MB.
Loading the file in Sketchup takes quite some seconds. Loading in Blender is MUCH, MUCH faster.
My simple question is: why is this so? Why is the Blender file much smaller?
And why on earth is zooming and panning in Blender so elegant compared to Sketchup’s behaviour???
Anyone to tell me what I am missing with Sketchup??
