How to calculate the total length of the molding?

[Anonymous]

Hello. There is a need to calculate the perimeter (length) of the wall (vertical) profile. I make it a morph and save it as an Archcade object, after that I place the created object on the plan.

After that, I create a calculation task and I do not find the calculation of the object along the perimeter.

How can I calculate the total length of the wall profile? There is a lot of it in the project.
P.S.: Sorry for my english, english is not my native language.
