Definition of planes - inclined plane

You can generate an inclined plane by transforming an existing AutoCAD polyline. The plane is defined for a selected (active) story. Using the plane, you can define structure elements (such as roofs) inclined to the horizontal plane of stories.

Note: You can delete an inclined plane only if no structure elements are attached to it.

Methods of defining an inclined plane:

In plan view

1. Indicate a polyline defined on a story plan (see the drawing below); Note: an inclination angle of the polyline determines the slope of the defined inclined plane
   
2. In the Definition of planes dialog, for Plane name, enter a unique name
3. Click , which enables defining the inclined plane
4. Specify parameters of the plane location:
   • Reference edge
   • Reference level (bottom or top of a story)
   • Offset of the plane with respect to a selected reference level, if needed
5. Click (Select).
6. In the drawing area, select the polyline
7. Specify the direction of polyline projection (in the direction of the X axis or Y axis)
8. Select 2 points that define an area of the inclined plane.

In elevation view

1. Indicate a polyline defined in the side view of structure (see the drawing below); Note: geometry of the polyline determines the geometry of the defined inclined plane
   
2. In the Definition of planes dialog, for Plane name, enter a unique name
3. Click , which enables defining the inclined plane
4. Specify parameters of the plane location:
   • Reference edge
   • Reference level (bottom or top of a story)
   • Offset of the plane with respect to a selected reference level, if needed
5. Click (Select)
6. Select 2 points that define an area of the inclined plane.
