Plot Engine BeginDocumnet exception error.

[TSYUK]

Hello!

I'm trying to make plot file of DWG using AutoCAD SDK.

But, met a "eDataLinkSourceNotFound" exception message when calling Plot Engine's BeginDocument.

Pls, let me know how to handle this problem.

Thank you in advance.

The plot file generation program code as below.

ppo.AllowNone = false;

PromptPointResult ppr = ed.GetPoint(ppo);

if (ppr.Status != PromptStatus.OK)

return;

Point3d first = ppr.Value;

PromptCornerOptions pco = new PromptCornerOptions("\nSelect second corner of plot area: ", first);

ppr = ed.GetCorner(pco);

if (ppr.Status != PromptStatus.OK)

return;

Point3d second = ppr.Value;
