Is it possible to access source file which is used by creo to design lattice.
Basically i want to access the formula used by creo to design the formula driven lattices (DIAMOND).

Great article, but it would be nice if you added an example with navigation.
For example, in case of gyroid the governing equation is
U_g=cos〖k_x* x〗 sin〖k_y* y〗+cos〖k_y* y〗 sin〖k_z *z〗+cos〖k_z* z〗 sin〖k_x *x〗-t
Gyroid (G), lattice structures with arbitrary numbers of cells and volume fractions can be generated by finding the U = 0 isosurface of the gyroid equations.
Where
k_i=2π *n_i/L_i
with i=x,y,z
where n_i are the numbers of cell repetitions in the directions x, y and z, and are the absolute sizes of the structure in those directions.
In creo for n_i we can use pattern and for L_i it is “CELL Size” in GUI. I think there is no control over “t” in creo, absolutely fine. From these values, When I am trying to create lattice with some level of wall thickness, the lattice is very bad in 3D with uncontrolled thickened value. I think there is no control over surface generation.
My idea is, if I could somehow extract formulas used by the CREO, by this I can manually create the curve>surfaces from these formulas/equations.
Any suggestions appreciated thanks!
