Andrew Mac Posted October 15, 2008 Share Posted October 15, 2008 When creating roof faces , example I have say a 10:12 roof pitch going one and then another 10:12 roof pitch going the other, How do I cut the two roof so i have what would become a valley between the 2? Quote Link to comment
CipesDesign Posted October 15, 2008 Share Posted October 15, 2008 If they are at the same pitch, it's easy: simply draw the 45? line of their intersection, then use a polygon (or the reshape tool) to clip off/add on the needed areas. BTW: you can use the "add surface" and "clip surface" commands to add/clip a roof face, right in top/plan view. If they are at different pitches it is a tougher problem. Either "do the math" or use trial and error to find the line of intersection. HTH's Quote Link to comment
Tom G. Posted October 23, 2008 Share Posted October 23, 2008 Render your roof in OpenGL and trace the resulting intersection. Copy the marker and Paste In Place once in an editing view of the particular roof face. If you have trouble getting a line to stick atop the Open GL rendering, turn off Stack Layers or, if it's already off, the 3D Select tool may be on, rather than the preferred 2D Select tool.

willofmaine Posted October 24, 2008 Share Posted October 24, 2008 In plan, the angle of intersection between two different roof pitches is the ratio of their numerators (assuming both pitches are given in terms of the same denominator (or "run")). For example, the angle of intersection between a 10:12 roof and an 8:12 roof is 8:10. Quote Link to comment
