Another plugin that could make SketchUP into an environmental analysis tool just like Ecotect: 1001Shadows.

1001Shadows is a plugin for Google Sketchup that generates a series of shadow outlines from a start time to end time with user defined intervals.

  1. Simple operation – set the latitude, start-end time, interval and generate the shadow profiles
  2. Cross platform compatibility – Works in Sketchup Standard and Pro version, as well as Windows and Mac
  3. Capture shadows for export – Shadow profiles are generated in edges or faces(solid shadows) that can be exported to other CAD programs.

Previously we posted on other tools (even free) for solar and thermal simulation within SketchUP.
