Hi,wout I want to display the grid throughout the drawing area. Is DxfVPort the class? C# code: // create VPORT for initial view BoundsCalculator boundsCalculator = new BoundsCalculator(); boundsCalculator.GetBounds(model); Bounds3D VPortBounds = boundsCalculator.Bounds; DxfVPort active = new DxfVPort(DxfVPort.ActiveVPortName); active.Height = VPortBounds.Delta.Y; active.AspectRatio = VPortBounds.Delta.X / VPortBounds.Delta.Y; active.Center = (Point2D)VPortBounds.Center; active.GridSpacing = new Vector2D(50, 50); active.ShowGrid = true; model.VPorts.Add(active); Invalidate(); But there is no any effect,no grid is displayed.

Hi,wout,could you help me to solve the question above?How to display the grid just like the sample "Editor\Examples\WindowsApplicationCS"

Hi, The grid display of viewport classes is not implemented. - Wout

Oh,are all the property ShowGrid and GridSpacing(and GridIsAdaptive/GridAllowSubdivision/GridDisplayBeyondLimits/GridFollowsDynamicUcs/MinorGridLinesPerMajorGridLine) of DxfVPort Class invalid?But these property all seem to valid!Is there other way to display the GRID in cadlib?

CadLib will read/write the properties, but display is not implemented. - Wout
