The MPlane command sets a mobile construction plane to a selected object and maintain the relationship between the construction plane and the object.
When you move, rotate, or otherwise transform the object, the construction plane attached to the object transforms as well.
The update mode is controlled by Modeling Aids > Universal and Standard settings. Changing between Universal and Standard will not update the current MPlane until the object that the current MPlane is attached to is moved or rotated.
|1.||Select an object.|
|2.||Specify command line options and press Enter when done.|
|3.||Pick a location to establish the x-axis direction or press Enter to accept the previous x-axis direction.|
|4.||Pick a location to establish the mobile construction plane orientation or press Enter to accept the previous direction.|
The Vertical option sets the mobile construction plane vertical to the current mobile construction plane.
The ZAxis option sets the z-axis instead of the x-axis.
The Attach option sets a new mobile construction plane to an object.
The UseObjectPlane option sets the origin and orientation automatically and depends on the object type.
|●||Surfaces: The tangent plane at location on the surface midway in the U and V domains.|
|●||Curves: The origin is at the curve start point; the x-direction of the mobile construction plane is tangent to the curve at its start point, with positive x in the curve direction; the y direction is normal to positive y.|
|●||Clipping planes: The origin goes to the corner of the clipping plane icon, positive z is in the clipping plane's normal direction.|
|●||Polysurfaces, meshes, point objects: The current construction plane is moved so that the origin is at the center of the object bounding box.|
Automatically updates the construction plane when the object position changes.
With the No option, manually update the construction plane with the Refresh option.
The Detach option removes the link between the object and the mobile construction plane.
The Modify option changes the Automatic update options for an existing MPlane.
The Refresh option manually updates the construction plane when the Automatic update option is set to No.
The Show option displays an axis icon on the object to show the orientation of the construction plane.
