Facade Grid - [source code]
Analysis points with outward normals and per-cell areas over surfaces, at a spacing suited to a building rather than a district.
Input
| Name | Nickname | Description | Type |
|---|---|---|---|
| Geometry | G | Surfaces to grid: Breps, Surfaces or Meshes. | Geometry |
| Spacing | S | Grid spacing in model units. 1.0 suits a facade; coarsen it for a district. | Number |
| Offset | O | Distance to push each point off its surface along the outward normal, so the surface does not shade its own grid. | Number |
| Max Tilt | MT | Keep only faces whose normal is within this many degrees of horizontal — i.e. how far from VERTICAL a face may lean and still count as facade. 90 keeps everything, so roofs and ground are included. | Number |
| Flip | F | Reverse every normal. Use when a surface's own orientation points into the building and the outward test could not tell — the Sun Path diagram makes this obvious. | Boolean |
Output
| Name | Nickname | Description | Type |
|---|---|---|---|
| Points | P | One point per cell, offset off the surface. | Point |
| Normals | N | Unit outward normal per point, aligned with Points. | Vector |
| Areas | A | Area each point represents — feed Sun Stats or Sunlight Compliance so results are weighted by area rather than by point count. | Number |
| Grid | G | The analysis mesh the points came from, for colouring results. | Mesh |
| Report | R | Cell count, total area and what was filtered out. | Text |
