Not able to create a monochrome pdf in microstation with large content of vendor model contents in the section view. please help

Do you have monochrome checked in the print dial box? Create a pen table so everything prints Monochrome.

This is not the best solution but trying saving this in a new file or better yet reference it into a new file. Then go to Level manager and change all the colors white or gray.

Just some thoughts. I've never had this issue.

yes the print dial box is checked as monochrome but it creates pdf in color. how to create a pen table so everything prints monochrome ?

if I try printing without raster the large section is not getting generated. this is another problem. the pdf of this section view is not getting created

I believe the Help file has information about creating pen tables.
