How to define a plane

Several different methods are available to define a plane. When appropriate, all or some of the following options will also be available. Depending upon the option selected, additional selectors will be displayed in the selection list.


Method Usage and Selector details
On Face Enables you to define the plane as on of the one planar faces of a solid.

Face: Select a face of the solid.
3 points Enables you to define the plane as the one univocally identified by 3 points.

3 points: Select three points to define the plane such that:
  • The first point identifies the center of the plane.
  • The second point identifies (starting from the first) the X-axis of the plane.
  • The third point is a through point not aligned with the previous two.
Plane Enables you to define the plane as an existing one.

Plane: Depending upon the feasibility, you are allowed to select a planar face, datum plane or one of the reference planes.
Through axis & point Enables you to define the plane contained by an axis and a point.

Axis: Select an axis lying on the plane. Click here for details.
Origin: Select a point to define the origin of the plane. By default, a point gets selected upon making the selection of the axis; you can change it. Point: Select a point through which the plane passes.
Perpendicular to axis & through point Enables you to define the plane as perpendicular to a direction (defined by a selected axis) and passing through a point.

Axis: Select an axis to which the plane will be perpendicular to. Click here for details.
Origin: Select a point to define the origin of the plane. By default, a point gets selected upon making the selection of the axis; you can change it. Point: Select a point through which the plane passes.
Coefficients To define the plane through the coefficient values of its cartesian equation (Ax+By+Cz+D=0), to be specified in the respective mini-dialog boxes (Coeff. A, Coeff. B, Coeff. C), and through a point to indicate ( Point).
