By applying the Defines Slope property to lines of a roof boundary, you can create different types of roof lines. (See Examples.)
- In sketch mode, select a roof boundary line that defines slope (indicated by ).
- On the Properties palette, select or clear Defines Roof Slope.
- To specify roof pitch, select a slope-defining boundary line, click the numeric slope definition in the drawing area, and enter a value for the slope.
You can specify the format of the Slope property in the Project Units dialog.
One sloped line forms a flat roof
Two opposite sloped lines form a gable
Three or four sloped lines form a hip roof
Other roof footprints and sloped lines yield different results
