Massprop for arrayed objects

I have a simple 3D cuboid that I used rectangle array on, 2 rows of 5 elements each.

Anyways I then tried to use massprop on the 10 objects to get the combined volume.

But I get: "No solids or regions selected." whenever I select the arrayed objects.

To create the initial object I offset an existing objects square face using "Offset Edge". Then I arrayed the resulting offsetted square shape. I then "Extruded" the shapes by editing the source.

Anyone have any idea what the problem is, or how to reach a solution?

When you extruded the shapes what did you end up with? An extruded surface?

I'm not sure how to check for that.

What I ended up with is a bunch of solid, cuboid objects.

I simply clicked on a square shape I created from offsetting another single cuboid's face, so I ended up with a 2D square which I simply used the Extrude tool to create a 3D shape.

Since I arrayed for the rest of the objects, the fact that associative properties exist makes it so the 10 objects are still grouped together as related. So that when I highlight one of them, I automatically highlight the rest of them as well.

I'm not sure if this is any more help for you to clear this issue up.

Well first of all you're dealing with a block. Explode it and try again.
