How can I get lines to show up between similar wall materials in section?

[svalen]

For examples I am showing Footing a 24" hi wall under a 10" foundation wall. 

In section now line appears between the footing and foundation  wall.

I understand there is a tool to show lines between joining materials in plan, but how can I

get these lines to show in section?

Use the Unjoin tool:
