Okay, this is driving me nuts. I have a bunch of 4 x .5 x 1 boxes which
are stacked corner to corner in a stair pattern. Given their layout, I
thought/assumed that they make a 30 degree angle with the ground (a
plane), but when I added another box on the side and rotated it up 30
degrees, it didn't line up with the blocks!

I'm stumped. Barring some kind of bug, I can't imagine why I'm having
this problem; the math isn't particularly complicated here. Can anyone
help me with this? Code and example image follow:

#declare stair_row = union
	{
	#declare stair_row_members = 1;
	#declare stair_row_count = 0;
	#while (stair_row_count < stair_row_members)
		box { <0, 0, 0> <4, .5, 1> }
		#declare stair_row_count = stair_row_count + 1;
	#end
	}
	
#declare stair_block = union
	{
	#declare stair_rows = 10;
	#declare stair_row_count = 0;
	#while (stair_row_count < stair_rows)
		object { stair_row translate <0, stair_row_count/2, stair_row_count> }
		#declare stair_row_count = stair_row_count + 1;
	#end
	}
	
#declare stair_rail = union
	{
	box { <0, -in, 0> <in*1, 0, 15> rotate <-30, 0, 0> }
	}

I'm using MacMegaPOV 0.7 (I don't care for the present interface of the
official beta) on Mac OS 8.6, if anyone cares.
