Meshes and reinforcing fabric

[KeesW]

I am looking for steel meshes and reinforcing fabrics. Has anyone written, or seen, such an object? Or should I make my own?

br=0.1 !mesh size

x1=3*br
y1=3*br
x2=ROUND_INT (a/x1)
x3=a/x2
y2=ROUND_INT (b/y1)
y3=b/y2
for herhy = 1 to y2
	for herhx = 1 to x2
	lin_ 0,0,0,x3,y3,0
	lin_ 0,y3,0,x3,0,0
	addx x3
	next herhx
DEL x2
addy y3
next herhy
del y2

Here's a quick dirty solution of simple 3d line mesh that I used to mock up a cast iron grid for windows. I prefer 3d lines, as solid models will bog down elevations with polygons, shadow casting etc.
