Automatic Sizing of Planes and Axes

Planes and axes that you create are automatically sized to either the geometry on which they are created, or to the bounding box of the model geometry. As the geometry changes size, the planes and axes update accordingly.

You can override the automatic sizing by manually changing the plane or axis size, which disables future autosizing for that entity. You can re-enable autosizing by selecting Autosize from the shortcut menu.
The created plane is 5% larger than the geometry on which the plane is created, or 5% larger than the bounding box. This helps reduce selection problems when planes are created directly on faces or from orthogonal geometry.

To see an example of automatic sizing of planes:

  1. Select a planar face and create an offset plane.

    Offset plane 1 appears and is automatically sized to the geometry of the face from which it was created.

  2. Click View > Planes.
  3. Edit the sketch to double the dimension of the bottom edge of the model, then exit the sketch.

    The plane 1 size updates automatically when you change the geometry of the face on which it was created.

  4. Drag upwards to manually resize the top edge of plane 1.

    Autosizing becomes disabled.

  5. Edit the sketch again to change the bottom edge dimension back to the original size, then exit the sketch.

    Plane 1 does not resize automatically because autosizing is disabled.

  6. Right-click plane 1 in the graphics area and select Autosize.

    Autosizing is re-enabled. Plane 1 automatically resizes to the updated model geometry.
