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 follows:

#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> }
	}

(An image demonstrating the problem has been posted in p.b.i.)

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.
