I know this is an old post, I know that, but the request is still valid. I would like for this feature to be added, as well as in with Multileader styles and Dim styles.
Style based works so much better for 3D objects like 3D Polylines and Feature lines. Style based is the only way I can actually show dashed versions of these types of objects.
The only reason I believe people are reluctant to switch to style based, other than being used to color based, are problems like these.
The main problem I have is that the _Dot block used in a dot leader head always plots as color and I have to switch it to a certain style, which you'd think setting it to byblock would work, but it doesn't. Also, dragged label states plot the leaders too thick, and sometimes regular dimension lines and leader lines do the same thing.
Please update, please, I'm begging you.
Should definately be able to put components of a label on a different layer than the main label, if we want to. I think that would basically solve this issue for stb and ctb users.
Credit where credit is due! Give kudos or accept as solution whenever you can.
