Parametrically moving geometries on a surface

[Joseph_Oster]

I used some buildings and code from a recent thread:

Combining a buildings list and sites list

You have ten buildings that aren’t sitting on a plot (red), 196 buildings that straddle two or more plots (yellow) and 222 buildings that sit cleanly on just one plot (green), perhaps shared with other buildings. [buildings_plots_2020Dec23c] buildings_plots_2020Dec23c.gh (3.3 MB) You can disable PShift in the white group and enable preview on the ColorB component to see the buildings as before. [buildings_plots_2020Dec23c2] The cyan group sorts the buildings by XYZ which is not necessary …

• The ‘Tree/List Viewer’ in this model colors all the buildings blue except for the one selected by the ‘list idx’ slider, which is displayed in yellow and treated as the one you want to move.
• The ‘X’ and ‘Y’ sliders (blue groups) move the selected building ± the X and Y values.
• If there are no collisions, the moved building is displayed in transparent yellow.
• If there are any collisions, the moved building is displayed in transparent cyan and the buildings it collides with change from deep blue to magenta.
