I'll try and never remove it but can't promise. Drop me a line if you can't get it from the above link.
The Xpresso program fits (x) number of slats within a frame. As the frame dimensions are changed, the spacing between slats is kept uniform. As the number of slats or their width changes, likewise the spacing between them remains uniform.
My intention is to use C4D to generate a lattice and export it for CAD use (in lesser programs : ).
The X and Y slats here are parametric cubes and I did not implement control over their Z axis as I do not need it.
I just want to say thanks again to Brian Jones who generously helped iron out a couple of flaws and got it working properly.
