MLeader Not visible

[rnilay81]

Hi All,

I am trying to create the MLeader and add it to the document. The code is running fine but nothing is visible on the model when dwg is opened. I tried to look in the tests but the tests only have the portion where it reads the file and asserts for the already existing MLeaders.

If there are any tests for this reason or steps we have for this, then please share.

Right now the code I have written is something like this. I am sure I am missing something or wrong somewhere.

var mleader = new MultiLeader
{
    ContentType = LeaderContentType.MText, // Use MTEXT for annotation
    ScaleFactor = 1.0, // controls arrow size and text size
    ArrowheadSize = 10, // the arrow block
    LineColor = ColorHelper.ResolveColor("Magenta"),
    // TextAttachmentType = MultiLeader.TextAttachmentTypes.AttachmentMiddleOfTopLine,
    
    //ContextData.TextLabel = "Leader Text"
};

MultiLeaderAnnotContext ContextData = new MultiLeaderAnnotContext();
ContextData.BasePoint = new XYZ(600, 100, 0);

mleader.ContextData = ContextData;
// Add a leader line
Line line = new Line
{
    StartPoint = new XYZ(0, 0, 0),
    EndPoint = new XYZ(1000, 1000, 0),
    Color = ColorHelper.ResolveColor("Magenta"),
    Thickness = 1.0
};
mleader.Arrowhead = new BlockRecord("Arrowhead");

mleader.BlockContent = new BlockRecord("Entity");
mleader.BlockContent.Entities.Add(line);

Hi @rnilay81,

This is a known issue, that I'm trying to fix:

• MultiLeader SPIKE #641

It seems that some default values of the MultiLeader are wrong, and that causes an error on the rendering.

When I figure it out what's failing, I'll post a provisional solution for your code until the issue is closed.

ok Thanks @DomCR for the reply. I will wait for the provisional solution.
