Create a Curved Curtain Wall: Geometry Methods

When defining the geometry of a curved Curtain Wall, you must first define the cylindrical Base Surface, then mark off the parts of this cylinder onto which the Curtain Wall will be placed.
Note: Curved Curtain Walls are always regularly shaped: the axis of its cylindrical Base Surface is either horizontal or vertical to the input plane when you create it, although subsequently you can tilt it in any direction.
1.
Centerpoint and Radius: Click to place the centerpoint. Click a second time to define the radius and one of the endpoints of the Curtain Wall. Click a third time to define the other end of the wall.
Click Place to close the dialog. The Curtain Wall is placed.
2.
Three Points: Click three times in succession to define the beginning point, another point, and the endpoint of the Curtain Wall. By defining these three points, the reference cylinder’s radius and centerpoint are also calculated.
3.
Tangential: Use this geometry method to place a Curtain Wall that forms a full circle. Click three times in succession to define three points on the Curtain Wall. By defining these three points, the reference cylinder’s radius and centerpoint are also calculated. A temporary reference circle appears.
4.
Radius and Axis: Use this geometry method to create a regular arc-shaped Curtain Wall. This Curtain Wall will always be a half-cylinder shape placed on the input plane.
