<BR>
The size of the radii won’t matter (provided they’re all the same and smaller than the overall shape)...it has to be square to get 45deg lines. You’re simply taking a square and bisecting it with crossing lines that are at 45degree angles. Expanding the radii from 0 simply makes each straight segment smaller, it doesn’t change the drawing at all.<BR>
<BR>
I can draw the hourglass box and overlay a bunch of different radii over it without changing the overall shape.<BR>

It should always be a little wider than it is tall. If not, then the diagonals are not 45 degree lines. Draw it on paper, or with CAD, and you will see.<BR>

Basically you have two 45x45 right triangles with the right angle vertex's (the 90's) intersecting.<BR>
<BR>
In that case the vertical lines are twice the length of each triangles horizontal length (when oriented as an hourglass), therefore two of them equal the height of the verticals....and a square you have!<BR>
<BR>
The 45 lines end up being about 1.4 times longer than the vertical lines, if you fly the correct geometry.<BR>
