Using similar triangles to build a better roof. Description here in pdf format.
Hipnc sample file to illustrate this concept here.
Roof Peak Windows. Example betterRoofH18WithWindows.hipnc
This could also be done in expressions rather than a point wrangle but the point wrangle was used to make the concept clear.
Roof Dormers. Example betterRoofH18WithWindowsAndDormers.hipnc
You can also extend this to have a roof Dormer or a Chimney. Similar triangles are cool!
For more information about dormers click here for wiki and here for this old house.
