Slope Analysis by Angle/Percentage
-
I was in a bit rush today and i have no idea if I can do this task in instant using sketchup but I was looking for a slope analysis plugin for sketchup, I found 2 the color by slope and Color by Z of Chis Fullmer. However, I cant find its use in my field or even its overall plugin purpose since I can't input the percentage of slope or angle for every assign RGB i enter. Hope anyone can answer my question.
Thanks.

Thanks TIG for your response, but is there a way I can do this on a large scale land or similar to Chris Fullmer plugin that is has color value per slope. I saw your post in Chris Fullmer Color by Slope where should replace the original ruby script in notepad by the one you generate however, I don't know which file should I replace with the one you post or if i should remove all the scripting text and replace it.

I think Chris's tools have moved on from those old posts...
His ColorBySlope tool colors facets according to their 'angle'.
In his Plugins subfolder's ..._data.rb near the end you can see how the faces are processed and their angle is calculated as 'segment' [as an integer].
The array of materials [matarray] is inspected and the material number corresponding to the 'segment' is assigned to the facet...If you setup 90 colors then for each degree of slope you get a correspondingly colored material on the face...
With just 9 colors you get a 10 degree range of slope between flat and vertical.So for example - set 'low' to green [0,255,0] and high to 'red' [255,0,0]
Then the steeper the slope the redder it gets ?
The flatter the slope the greener it gets ??
Not all colors will get used - r.g. if the majority are quite flat it's predominantly greens as there are no steep red parts !
