Click the Align with work plane button () to rotate and move the camera to see the work plane from the top down.

Click to toggle the Work plane clipping button () on and off. When on, use it to cut away all geometries above the work plane and make it easier to draw when objects are overlapping within the work plane. The clipping is not done when looking at the work plane from the side.

Under In-plane visualization of 3D geometry, specify how to visualize 3D objects in the work plane (as blue curves and points) by selecting one or more of the following check boxes (all of them are selected by default):
|
-
|
Coincident entities (blue) — Show edges and points (in a pure blue color) that lie in the work plane.
|
-
|
Intersection (cyan) — Show the intersection of 3D geometry and the work plane (in cyan).
|
-
|
Projection (light blue) — Show the projection of all edges and points onto the work plane (in light blue).
