Unfortunately, current SketchUp Collada (DAE) format has limitations for metric users (or anyone needing units other that inches.) See the following topic:
After much hair pulling, I realized why the units of my dae exported from Sketchup were showing the wrong units in MonoGame and Jitter Physics Engine.
It appears Sketchup is exporting in inches, despite the fact I have units set to millimeters in Sketchup.
Is it possible to change this behavior?
I must have units in millimeters so MonoGame and Jitter Physics Engine can compute inertia in the appropriate units (among other reasons).
It is troubled because floating point rounding errors due to…
