Generate a two-dimensional grid consisting of regular triangles.

Input parameters:

1. Pl → Grid origin and orientation plane.
2. Nx → Integral number of cells in the grid X direction.
3. Ny → Integral number of cells in the grid Y direction.
4. Sz → Size of triangle edges.

Output parameters:

1. Pt → Points on the grid. Point structuring (flat, rows, or columns) can be modified from the component menu.
2. Cl → Grid cell outlines. Cell structuring (flat, rows, or columns) can be modified from the component menu.
