Solids or compound solids are not allowed as input shapes. Normal compounds are currently not allowed, too. Future versions will check the actual shape type of compound objects.
A [[Sketcher_Workbench|Sketch]] can be used as well. Solids or compound solids are not allowed as input shapes. Normal compounds are currently not allowed either.

==Notes==

*If your version of FreeCAD has a check box for Solid in the Revolve dialog, you can make Solids from closed Wires and Edges.
* [[App_Link|App Link]] objects linked to the appropriate object types can also be used as shapes and to specify the axis. {{Version|0.20}}
*If Revolve is performed using an axis that intersects the face to rotate, and you want to create a solid, the result might be invalid. This can happen for various reasons, self-intersection, direction, etc.
* If the object to revolve intersects the rotation axis the operation will fail in most cases.

Description

Revolves the selected object around a given axis. The following shape types are allowed, and lead to the listed output shapes:

Input shape Output shape
Vertex Edge
Edge Face
Wire Shell
Face Solid
Shell Compound solid (Compsolid)

A Sketch can be used as well. Solids or compound solids are not allowed as input shapes. Normal compounds are currently not allowed either.

The Angle argument specifies how far the object is to be turned. The coordinates move the origin of the axis of revolving, relative to the origin of the coordinate system.

If you select a user defined axis, the numbers define the direction of the revolving axis with respect to the coordinate system: If the Z coordinate is 0 and the Y and X coordinate are non-zero, then the axis will lie in the X-Y-plane. Its angle is such that its tangent is the ratio of the given X and Y coordinates.

Notes

  • App Link objects linked to the appropriate object types can also be used as shapes and to specify the axis. introduced in version 0.20
  • If the object to revolve intersects the rotation axis the operation will fail in most cases.
