Getting value of Z Coordinates 0 when working with YZ or XZ Plane.

Hi When I try to get the Coordinates of my mouse in AutoCAD sometimes I get Z coordinates and sometimes I get Z coordinates as 0. Is there any way to solve this bug? I am not using any code, It is just happening by default in AutoCAD behavior.

Your screenshots suggest that you're not in the WCS or the view is not parallel to the WCS XY plane.

Hi, How do I check If I am in WCS or the view is not parallel to the XY plane?

You can check if the current view direction is parallel to Vector3d.ZAxis.

public static bool IsCurrentViewPerpendicularToXYPlane() { var ed = Application.DocumentManager.MdiActiveDocument.Editor; using (var view = ed.GetCurrentView()) { return view.ViewDirection.IsParallelTo(Vector3d.ZAxis); } }

Similar to @_gile 's solution, this will tell you if the current view is a plan view of the current UCS:

public static partial class EditorExtensions { public static bool IsPlanUCS(this Editor editor) { if(editor == null) throw new ArgumentNullException(nameof(editor)); return editor.GetCurrentView().ViewDirection.IsParallelTo( editor.CurrentUserCoordinateSystem.CoordinateSystem3d.Zaxis); } }

Hi, @ActivistInvestor, @_gile I think I haven't described my problem correctly so I have made one small video for Your reference. When I am working on the Top view which is the XY plane I am getting the coordinates of XY correctly but when I change my view to Left which is the YZ plane then at a certain point I am getting the value of X and Y coordinates only and after a certain point I started to get the value of Z Coordinates. Why this behavior is happening?
