Annotation line width

[yes_and_no]

I tried to increase annotation line width.

It seems to only be able to increase to .39mm.

After that (limit) nothing changes 

Am I correct ?

[ToanDN]

What for?

[yes_and_no]

I might have used wrong term, perhaps line weight or line thickness...

You didn't read my question?

[ToanDN]

What specific elements do you want to alter the line weight in your project?

No.

We do asbuild plans that have HVAC ducts.
Without engage ourselves in documentation non-architecture items in detail,
we do want to show approximate duct size, without actual doing revit ducts
nor double-line drafting ducts where we can be held responsible if one
measures them on revit files. Current solution is having main duct in
single line, in widest weight (~18" in 1/4" scale) and branch duct at less
weight scale.
It happens on my project the main ducts are 48", 36", 24", all wider than
default #16, which is .039mm. I tried to increase the line weight without
success.

I thought you were talking about annotation lineweights. What do as builts and ducts have to do with your OP?

[ToanDN]

Those are not annotation lines.  Annotation lines are text leaders, tag and symbol lines, title block lines.

What is this "nothing" that changes?

You really need to do a better job at explaining yourself from the beginning... This is a recurring issue you're having. The fact that you respond with smart*** comments to people that try to provide some help based on the little info you give doesn't help.

You can include disclaimers in your Revit model that clearly state that the model is not to be used for exact measurements to clear up this whole issue.

similar to this, duct lines are single annotation lines (nevermind the dimensions)

They are NOT annotation lines unless you draw them directly on sheets.

Are you drawing lines over your ducts? I know you said that but I didn't think that you really meant it.
