Can't Change the Justification and Scale of MLINE with VBA

Recommended Posts

Hi,

 

I'm trying to draw a MLINE using the vertex of a Polyline and that part of the macro works ok, but when I try to change the justification and/or the scale of the MLINE changing the system variables before drawing the MLINE, it doesn't work, I always get the same justification and/or scale.

 

The strangest thing is that when I check the system variables in the command line they have the value the macro set but the MLINE drawn by the macro doesn't assume the new justification and/or scale.

 

What is the problem? Using Autocad 2009 or 2014. Here is my code>

 


Public Sub poly()
   Dim pline As AcadLWPolyline
   Dim multiLine As AcadMLine
   Dim points(0 To 5) As Double
   Dim mpoints(0 To  As Double
   Dim varData As Variant
   
   points(0) = 2: points(1) = 4
   points(2) = 4: points(3) = 2
   points(4) = 6: points(5) = 8
   
   mpoints(0) = 2: mpoints(1) = 4: mpoints(2) = 0
   mpoints(3) = 4: mpoints(4) = 2: mpoints(5) = 0
   mpoints(6) = 6: mpoints(7) = 8: mpoints( = 0
   
   ThisDrawing.SetVariable "CMLJUST", 1
   ThisDrawing.SetVariable "CMLSCALE", 3
   
   ThisDrawing.Regen acActiveViewport
   
   Set pline = ThisDrawing.ModelSpace.AddLightWeightPolyline(points)
   
   Set multiLine = ThisDrawing.ModelSpace.AddMLine(mpoints)
   multiLine.Update

   ThisDrawing.Application.ZoomAll
   
End Sub

 

Thanks

Try using MLine properties instead of system variables

for instance

    multiLine.Justification = acBottom
   multiLine.Lineweight = acLnWt005

Thank you, it worked. Just one correction, to change the Scale the property is MLineScale not Lineweight.

 

Regards.
