Structural Framing Lineweight changed with Coping applied

[tyler5SX4J]

Hi

I’ve noticed that applying coping to structural framing in Revit 2025.4 appears to affect the projection line weight. Specifically, once coping is applied, the line weight of the affected element changes unexpectedly in plan view. Additionally, I found that setting the coping distance to 0 removes the coping entirely.

I’m wondering if these behaviours are intended or if they might be bugs.

For context, I’m running Revit 2025.4 on Windows 10 (version 22H2).

Would appreciate any clarification or insight on this.

Thanks.

As regards the line thickness I can only assume that when Coped/Notched the Beam is being presented as Cut and not Projected as expected?

You can check this in the Object Styles and review the Liveweights and change them to see if this is the Case?

Coping distance is inactive if the member is not coped. therefore, you need to select members with a similar coping configuration to apply the coping distance.

Strange one in that initially setting to 0 it removed the Coping/Notch Parameter but when I edited the View Range I then got this message when repeating the process where okay leaves the Parameter in place with 0.0

If you disallow the join between the 2 elements you can cope with a 0 value

You appear to be applying coping to a Timber family, which is a little strange, since coping is really only useful to steel, as Jay has demonstrated. That being said, i would check your Timber family display settings (possibly symbolic line issue), as they do behave different vs steel families. Also, what is the structural usage of the member to the right of what you have selected in the image? Is it also a joist? if not, as Jay has suggested, check your object styles, you can have a different appearance based on the sub category/usage.

I use the coping a lot when doing wood framed buildings.  IF you never do wood framed buildings, you may not realize how helpful it can be there.  

Best-use depends on what your task is.
