How do I get the transformation Matrix of the block?
We know, “nentsel” returns the model to World Transformation Matrix.,
But if I wan’t to use “nentselp,nentsel”(maybe a lot of selections, or no why),how do I get the same matrix?

Actually,when the block isn’t in 3D status,in another word,its normal is(0 0 1),I can get the Transformation Matrix,because the Transformation Matrix is a little simple,but when its normal isn’t (0 0 1), e.g. (-0.8 0.5 0.4),I don’t know the formula,I searched a lot, but I didn’t find any formula about this Normal.

If a block has a 3d normal,e.g,(-0.8 0.5 0.4), When I turn on the properties of the block,I can’t change the Rotation Angle,it’s always the same value,and every change of value,it changes its Transformation Matrix and its look.
It has confused me a long time.
