Problem

I need to edit the properties of a wall assembly's layers, whether from the Schedules dialog or the Modify Properties tool, but those properties are greyed out. Is there any way to edit a wall layer's properties?

Solution

No, there is currently no way to modify the properties of a wall layer since they are not stand-alone components but rather part of the overall Compound Wall Assembly. The walls available in Catalog Editor aren't those that are used to create a Compound Wall Assembly - that process is performed using the Family/Part Editor instead, with each layer's height and width/thickness values defined within the Compound Part definition:

This means the wall layers are linked to the respective Part assignment and its settings, which is why they display as "default" in the Schedules dialog, a generic catalog assignment used so that they display for reporting purposes.

The best option is to create and/or vote on an IDEA requesting this ability: https://openbuildings.ideas.aha.io/

In the interim, a potential workaround is as follows:

1. Instead of placing a single Compound Wall Assembly, place the individual walls that would make that assembly positioned relative to each other as needed.

2. Place a line along the center and use the Add Instance Data tool to attach the desired wall assembly catalog data to it:

3. Create a Named Group to group the walls and line together in lieu of an actual assembly:

4. Next, copy the line's (wall assembly) ID number and paste it as the value of a specific property of each wall - the ID|Notes property is used in this example:

5. Last, add that property to your schedule - see the custom wall assembly/layer schedule outlined in this wiki:

The compound wall's (which is a line) ID value can then be used to visually "connect" each wall layer to its group/assembly as shown here:

While this method requires a few extra steps, it provides a way to move or otherwise manipulate the individual walls as a single entity, report all of their values in the Schedule dialog, and most important, all of the wall "layer" properties are available and can be modified as needed.
