Well, that was me trying to simplify the query for HN audiences. Let me recall the actual conversation.

Me: How to add missing monochrome.ctb file in autodesk dwg trueview?

[Upto this part google is same. Pointing to the same link, but not showing any steps though.]

Copilot: Here are the steps. Put them here in this folder......

Me: I put it there as suggested. Still didn't work. How to make tureview refer another folder location?

Copilot: Here are the steps.

Me: It worked thank you. [I really thanked it ;)]
