.NET

[#1]

Hi,

I am trying to Change the Color, Line Type and Line weight in Properties Pallete without selecting any objects, but i don't know how to do this.

[#2]

Those are controlled by the drawing's Current sysvars.

CECOLOR

CELTYPE

CELWEIGHT

[#3]

Can you guide me, to use this in .net code

[#4]

Untested

using AcadApp = Autodesk.AutoCAD.ApplicationServices.Application;

// AcadApp.SetSystemVariable(string name, object value)

	AcadApp.SetSystemVariable("CECOLOR", "BYLAYER")
	AcadApp.SetSystemVariable("CELTYPE", "ByLayer")
	AcadApp.SetSystemVariable("CELWEIGHT", -1)

 Regards

[#5]

On using the above code,

AcadApp.SetSystemVariable("CECOLOR", "BYLAYER")- Results No Change

AcadApp.SetSystemVariable("CELTYPE", "ByLayer")- Results in "eInvalidInput" error

AcadApp.SetSystemVariable("CELWEIGHT", -1)- Results in "eInvalidInput" error

Works for me. ... see attached piccy.

I don't know why it is not working for me.....

But i got the solution in another way, my solution code follows,

Using lock As DocumentLock = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument.LockDocument
Dim acDoc As Document = Application.DocumentManager.MdiActiveDocument
Using acTrans As Transaction = acDoc.Database.TransactionManager.StartTransaction()
acDoc.Database.Celweight = LineWeight.LineWeight015
acDoc.Database.Cecolor = Autodesk.AutoCAD.Colors.Color.FromColor(Color.Red)
Dim acLineTypTbl As LinetypeTable
acLineTypTbl = acTrans.GetObject(acDoc.Database.LinetypeTableId, OpenMode.ForRead)
Dim sLineTypName As String = "Continuous"
If acLineTypTbl.Has(sLineTypName) = True Then

'' Set the linetype Center current
acDoc.Database.Celtype = acLineTypTbl(sLineTypName)
'' Save the changes

End If
acTrans.Commit()
End Using
End Using

But the Only Issue in above code is we can't reback to "ByLayer"

[#9]

Please clarify your last post. ??

And the code you posted is different to your initial question  ... but I see how I could confuse your intent.

Hi,

>> we can't reback to "ByLayer"

Why not, this code does not Work?

acDoc.Database.Celtype = "byLayer"
