This disables any defined automatic Workplane modes and fixes the Workplane. You will automatically be switched to this Workplane if one of the commands below is selected. The orthographic views (that don’t adapt accordingly in the automatic modes when the Workplane is modified in the Perspective view) will be adjusted accordingly; the tip view will be perpendicular to the Workplane, etc.
Automatic Workplane Modes
Depending on which one of the 3 following modes is selected, the Workplane will be positioned automatically.
Depending on the angle of view of the camera, one of the world coordinate planes will always automatically be displayed as the Workplane. This, for example, lets you create Splines at right angles to each other (e.g., for piping); when setting points, Workplane and Grid Point must be enabled in the Snap settings.
The Workplane will be positioned perpendicular to the camera’s angle of view (Z axis) and 500 units from the camera. All new objects created will be created at the center of view.
In this mode, the Workplane will orient itself according to:
If enabled, the Workplane will automatically be positioned on each polygon over which the cursor is hovered (as long as the mouse button in not pressed). If no polygon lies underneath the cursor, the Workplane will orient itself according to the currently active mode (Planar, Camera or Axis).
In this mode you can move vertices, edges or polygons onto any polygon. By hovering the cursor over the respective polygon, the Workplane will position itself over this polygon. Clicking the mouse button will move the selected element onto this polygon (3D Snap and Workplane must be enabled in the Snap settings).
This functionality makes it easy to, for example, arrange objects perpendicular on the surface of other objects.
In this example, we want to position a cone on the surface of this platonic shape.
To do so, the
Proceed as follows to position a cone perpendicular on a surface:
