Projecting extruded roof by free profile

9.8.2.6. Projecting extruded roof by free profile

Using this command you can draw a roof with any shape by customizing the profile. This command is similar to the previous one, however, here you have to define the vertical cross-section of the roof. You can also project the roof thus drawn onto an automatic roof, this way creating a so called “bull’s eye roof” for instance (see the example bellow).

You can project the so called “bull’s eye roof” onto the automatic roof by clicking on the Project extruded roof command.

Define the height of the points indicated by the program.

Using this command you can place a roof above a staircase as well. See the example. You can insert a profile with different predefined height values on an open path or a free profile.
