Revolved Shell with Freely Defined Profile
1.Activate the Shell Tool and choose the revolved geometry method with detailed input method.
On the Floor Plan:
2.Draw the Shell profile - a polyline or a closed polygon - with the usual polygon input method.
3.Double-click to complete the polyline or polygon.
4.Click twice to draw the revolution axis. The initially placed revolution axis is always parallel to the Floor Plan, though you can edit it later.
5.In the appearing dialog box, enter the Shell’s revolution angle. A positive number will revolve the Shell toward you. A negative number will revolve the Shell away from you.
6.Click OK to complete the Shell. View it in 3D.
In the 3D Window:
1.Choose the input plane. Either click to find the default plane, or choose another input plane based on existing elements. This is the plane on which you will draw the profile and then its revolution axis.
•If you click in “empty space”, the default input plane is at the base elevation defined in Shell Default Settings.
•To place an input plane defined by points or surfaces of an existing element, choose it by clicking on any points and/or edges or surfaces: the automatic feedback (a gray square) will show you where the potential input planes are. When you get the plane you want, click to make it appear.
2.Draw the Shell profile - a polyline or a closed polygon - with the usual polygon input methods.
3.Complete the polygon.
4.Click to define the center of the revolution axis.
5.Move the cursor to complete the revolution axis. (Navigate in the 3D view to find the best angle for seeing the feedback.)
6.The Shell is complete.
