Summary: Discusses how to create isometric views using RhinoScript.
AutoCAD has a VPOINT command that allows you to create isometric views of the model. Does Rhino have anything similar?
The VPOINT command uses the point entered by the user to create a vector that defines the direction from which the drawing can be viewed. You can do this in Rhino using the ViewportProperties command. In the ViewportProperties dialog, first set the view to parallel projection. Then, set the target location to 0,0,0 and the camera location to where you want to be viewing from.
If this seems too cumbersome, then you can also use the following RhinoScript subroutine:
Sub VPoint Dim strView strView = Rhino.CurrentView If Rhino.ViewProjection(strView) = 2 Then Rhino.Print "Viewport must be set for parallel projection." Exit Sub End If Dim arrOptions arrOptions = Array("NE Isometric", "NW Isometric", "SE Isometric", "SW Isometric", "User Defined") Dim strOption strOption = Rhino.ListBox(arrOptions, "Select viewing direction", "VPoint") If IsNull(strOption) Then Exit Sub Dim arrCamera Select Case strOption Case "NE Isometric" arrCamera = Array( 1, 1,1) Case "NW Isometric" arrCamera = Array(-1, 1,1) Case "SE Isometric" arrCamera = Array( 1,-1,1) Case "SW Isometric" arrCamera = Array(-1,-1,1) Case Else arrCamera = Rhino.GetPoint("View point") End Select If Not IsArray(arrCamera) Then Exit Sub Dim arrTarget, v arrTarget = Array(0,0,0) v = Rhino.VectorCreate(arrCamera, arrTarget) If Rhino.IsVectorTiny(v) Then Exit Sub Rhino.EnableRedraw False Rhino.ViewCameraTarget strView, arrCamera, arrTarget Rhino.ZoomExtents strView Rhino.EnableRedraw True End Sub
