How to exclude hidden layers when exporting PDF from DWG

dancefly09 · Post by **dancefly09** » 17 May 2023, 10:43

Some entities in the dwg file are scattered on different layers. I set one of the layers as a hidden attribute, and then exported this dwg file to PDF through cad.net. The generated PDF still presents the entities on the hidden layers. May I ask if there are any relevant options to control whether hidden layers are not exported when exporting PDF？

Hello,

If a layer is frozen or invisible the CAD entities it contains will also be invisible. If a layer is invisible but not frozen and it contains inserts of blocks belonging to visible layers then those blocks will be visible.

Please use the code below:

if (cadImage != null)
{
foreach(CADLayer l in cadImage.Converter.Layers)
{
if (l.Name == "0") l.Visible = false;

}
}

Kind regards,
