To impose the drawing plane:
- Click on the button
. The following dialogue appears:
- When you’re drawing in a 2D plane, it will always be a plane parallel to the global XY, XZ or YZ plane. If you want to draw in a top view, you will draw in the plane assigned to the equation ‘Y = …’.
When the Level manager is active, the Y-coordinate of the horizontal drawing plane will always be equal to the active level. - Similarly, you can draw in a vertical plane assigned to the equation ‘Z = …’ or ‘X = …’
You can also set the drawing plane by entering the coordinate of the drawing directly into the pallet 
.
