I am having some display issues with blocks in Rhino for windows. The geometry in the blocks is fine but it is being displayed with the shading inside-out (see images) or sometimes the shading is not in the correct place, like when the model is miles away from the origin, however the blocks are relatively close (within 70,000 mm). When editing the block with blockedit, the geometry is shaded correctly. Issues are with both rendered and shaded views (though I have not tested others). Going into the block and “refreshing shade” seems the temporarily correct its self for a shot period of time.
Any Ideas on how to correct this?
