(A double-post from the Discussion section, but this post should probably live here...)
I put together a utility definition to create a grillage (waffle) surface for laser cutter fabrication. Please feel free to use it (at your own risk...). I plan to make improvements to this base configuration in the future.
_Specify the uniform spacing for each of two (A = above, B = below) orthographic cut planes;
_Specify the rotation (angle) of the orthographic cut planes to the reference surface;
_Fine tune the start of A or B cut planes by shifting each independently;
_Specify rib height and notch thickness;
_Automated layout of the rib sections for fabrication including notches and labels;
_Visual 3D reference guide for construction;
_A "defaultGrillage" state has been saved under the "Solution" menu for quick start-up;
_A "generate_grillage_layout?" on/off toggle to allow for faster operation.
_The reference surface must always be shrunk;
_The grillage (for now...) is generated from a vertical extrusion downward. A surface with extreme geometry may not work well, if at all;
_If the outline of the reference surface is such that a section plane will cut the surface in two locations the automated layout will not function correctly;
_The notches are generated as rectangles with the intention that the user will want to cut the notches on a separate pass from the rib sections;
_Without any clusters, the canvas looks pretty scary. The resulting output of the definition is located all the way downstream (but should be clearly labeled).
