the 3dsmax sdk frustration

3dsmax sdk gives me so much love... not. Today found out (the hard way) that their BitArray.EnumSet function is broken in 64 bit...

on a sidenote the SDK states if you want something you draw in viewport to have a fixed nonscaling size, to use
vpt->GetVPWorldWidth(wpt)/360.0f;
however this isnt correct, you want to use
aspect = ((float)gw->getWinSizeX()/(float)gw->getWinSizeY());
aspect = max(aspect,1.0f);

(vpt->GetVPWorldWidth(wpt)*aspect)/(float)gw->getWinSizeX();
