You create an inclined plane of a determined shape and slope by transforming an indicated projection of the roof surface contour. It is defined for a selected (active) story. You can define successive roof surfaces on which elements of the roof will be defined.
To define this plane type (see the drawing below):
Define the shape of the contour of an inclined plane:
Using an inclined plane with a defined shape and slope, you can define multi-pitch roofs. Each roof surface needs to be defined separately. However, if the contour is symmetrical, only half of the roof surface needs to be defined.
An example of a multi-pitch roof created using this type of plane is shown.
