Measuring odd shape Extents

I feel like I am missing something really obvious here but I cant seem to find an easy way to measure the extents for a group or component?

If a shape has a obscure shape (say a tree) I just want to be able to see the maximum Width depth and height. Essentially the dimensions of the bounding box.

is there an easy way to do this?

Auto-dimensioning a 3D tree

and if you just want the bounding box, but not the dimensions there is this

You can also use the built in Dynamic Component, add attribute, to get the info:
comp_attr

Or you can use this old plugin from: [Plugin] jf_get_dimensions.rb | sketchucation

I packed it to rbz for you to be easily install by Extension Manager.
4Qwg_jf_get_dimensions.rbz (1.2 KB)

jm_get_dim

The other one is

selection-detailer

(I did not tried this)

You can try this plugin SketchUp Plugins | PluginStore | SketchUcation
