Add a Single Slope

With this function, you can add a horizontal structure as a single plane. The plane can be either horizontal or inclined. In both cases, you can define the elevation of the plane according to either its top or bottom surface. When you are adding an inclined plane, first select the points defining the pitch of the plane. After this, you can define the plane's edge line either by clicking the line points one by one, or by selecting the walls limiting the plane. The status bar displays the height, thickness and material code for the plane to be added.

Adding a Horizontal Plane

1. Select the definition of the elevation of the plane according to top or bottom surface. Select either of the following from the auxiliary menu:
   • Horizontal area by top plane
   • Horizontal area by bottom plane

   The plane height is the default height defined in the project parameters. You can change the height by clicking the button again.

2. Define the height, if necessary.

   Select Height with 3D Levels Dialog Box

   In the model window you can define the height by selecting a point or a surface. You can first select wire frame as the method of representation of the model, in which case it is easier to select points of the model.

3. Select the method of adding the edge line from the auxiliary menu:
   • Add by Points
   • Add by Walls
4. Select the points or walls limiting the plane.

Note

• You can restore the default top surface of a horizontal plane by using the function Restoring Default Height. The default value is read from the project parameters.

Adding an Inclined Plane

You can use this function to define the pitch of a single ceiling slope to match the pitch of a roof slope, for example.

1. Select the definition of the elevation of the plane according to top or bottom surface. Select either of the following from the auxiliary menu:
   • Area by top plane
   • Area by bottom plane
2. Select the points defining the pitch of the reference plane, and type their location heights. When the drawing window is active, you can define the pitch of the plane and the height of the selected surface (top/bottom) by selecting a reference plane using four points. Click the points one by one, and type the location height of each point in a dialog box. The first three points define the pitch of the plane, which means that the height of the fourth point is insignificant.

   Enter Height Dialog Box

   If you click the points of the reference plane in the 3D model, you can first select wire frame as the method of representation of the model, which makes it easier to select the points of the model.

3. Select the method of adding the edge line from the auxiliary menu.
   • Add by Points
   • Add by Walls
4. Select the points or walls limiting the plane.
