OpenSCAD For Loop Grid example
Profiles & patterns
Lesson 7 of 22
Generate many related solids from two loop variables and a height formula.

How this model works
OpenSCAD ranges include both endpoints, so [0 : columns - 1] produces exactly columns positions. Each height depends on both X and Y indices. These pillars are intentionally disconnected: STL can contain multiple shells, and that alone is not a compiler failure.

Make it your own
Change the height formula from x + y to abs(x - y). Add a thin base under the grid if you want one connected object.
Change one parameter at a time and inspect the result. Use the workspace reset action to return to this lesson’s original model.
