Hi Ola, that's good news that reducing the display mesh density helps, that will also help keep memory consumption down a fair amount as well.

One thing that can help to reduce detail for little nuts and bolts pieces is to use the "Avoid smaller than" option in the expanded dialog at export time.

That lets you enter a distance, and any polygons smaller than that size will shift to get a much rougher mesh on them, things smaller than that size will get meshed to an angle of 35 degrees.

So if you enter in a distance about the size of one of those bolts, that will probably help to reduce the generated mesh density by quite a bit.


If its the more dynamic movement aspect of the moving and scaling that is bogging down, one other thing you can try is to enter numeric scale factors rather than picking points with the mouse.

For example if you want to scale all objects down to 1/100 of the current size, push Ctrl+A to select everything, then run the Transform / Scale command, and now type 0 <enter> to specify the 0,0,0 origin point for the scale's origin, and then type 0.01 <enter> for the scale factor.
