[req] plugin for Slope analysis

[john2]

Hello everyone

I have an autocad file of site plan having contours. It is all in 2D form. A flat drawing with all the contours and labelled with their levels. I have made the terrain one by one placing the required lines on different levels

I want slope analysis like this

0-5% ------ very light brown

5-10% -----little dark brown

10-15% ---more dark brown

and so on till 25% and above ----- darkest brow

How can I do it?

Or can anyone make a plugin for it. I have already used colour by slope [Chris fullmer] plugin does this by itself not letting me put values.

I'll PM you an adjusted version of Chris's color_by_slope for you to test...

Unfortunately the saved 'sent' messages expire about a week too late.
So I can't re-get that file.
I also can't find it on my system - too many rebuilds, new PCs etc !

You could look at rewriting parts of color_by_slope...
Swapping its 'Z' rules for angle=face.normal.angle_between(Z_AXIS) with some if test rules like angle >= 1.degree etc

However, I think @sdmitch probably has something... look here...
