Dimensioning an Arris or edge of a 3D triangle

Greetings to All

I have drawn a simple model of a roof and want to dimension it but I am unable to locate a dimension along the hip edge. Any attempt to do this results in a dimension being shown along the red or green axis.

Any ideas please?Calculate Hip Length.skp (181.6 KB)

Do you mean like the dimension shown in bold text?

Temporarily change the model axes to align with the plane of that edge. Add the dimension. Don’t forget to reset the the axes afterward.
