(...) Dunno if it helps, but you can use L3P and find the view you like. The view matrix which corresponds to that view can then be found under the Test -> Statistics menu item. Fredrik (23 years ago, 23-Oct-01, to lugnet.cad.mlcad, lugnet.cad)

(...) Great, thanks! But I sort of (as Kevin does) need the way to generate the rotation matrix from a dialed in rotation value... if someone has a spread that does that, it would be nifty. (23 years ago, 22-Oct-01, to lugnet.cad.mlcad)

(...) Just my 2¢: The 3D angles (in degrees) in MLCad can be found under Settings>General>Cha...>Documents tab. They are indeed 23 and 45 degrees. --Ryan (23 years ago, 22-Oct-01, to lugnet.cad.mlcad)

(...) Those numbers are the values of a rotation matrix about the X, Y and Z axis. (Search for "rotation matrix" on google.com for an explanation.) The -A syntax has been around since ldraw.exe and is documented in ldraw.doc as well as the ldlite (...) (23 years ago, 22-Oct-01, to lugnet.cad.mlcad)

(...) Yes, that's it. Or so close as not to make a difference. THANK YOU!!!! This may actually be a candidate for the MLCad helps unless I'm the only person who ever wanted to render at the same rotation MLCad uses. (23 years ago, 22-Oct-01, to lugnet.cad.mlcad)

(...) If it's just differently rounded then that's not it. (the one Don gave wasn't it either I don't think, the initial rotation should be 45 degrees rather than 60, I think... ) If I could get MLCad to tell me what matrix it was using for a (...) (23 years ago, 22-Oct-01, to lugnet.cad.mlcad)

(...) We had a discussion about the "natural" and "oblique" matrices about a year ago where it turned out the "natural" matrix did some rather UN-natural shearing. (URL) mlcad is using this matrix: 0.5,0,0.866025,0.433...5,0.433013 Which is a 60 (...) (23 years ago, 22-Oct-01, to lugnet.cad.mlcad)

If you look into LDraw.ini, you'll find the post: Natural=0.625,0,1.07...1.25,0,2.5 quite similar to the one you asked about (I call it Larry here): Larry=0.63,0.00,1.08...,0.00,2.50 They're just differently rounded. /Tore (Tip of today: You may add (...)
