Simply Fix?

I'm having an issue with the ptmorph2d command, normally it works fine, but for some reason when I convert the grid to a diamond grid it goes crazy. Anyone have this problem? Anything I should check that I'm not seeing right off? Thank You.

Don't know how the ptmorph2d command works but the diamod grid drastically changes the data structure.

The grid is just a matrix of points in rows and columns. Panels probably are defined by taking two consecutive points in a row, and two at the same index in the next row.

Now Diamond grid looks like it's removing every even or odd point from the original grid. If you apply the same quad logic again, you get trapezoid panels. This logic will eventually fail as every other row is one point shorter.

To get the diamond pattern, you'd need to take Points from three rows instead of two and select one, then two then one point.
