Hi!
Please help me to visualize the elements of a component/group. In the attached file I have a simple parallelepiped so I suppose to have 18elements(12edges+6faces) dispite this I have 20elements. How can I find the extra two elements, I tried in Entity info but it shows only the number of elements so I can’t identify the extra elements, Outliner does not help either. What is the fastest way to do this?

You have two edges that have two segments.
You also have some reversed faces.
hello,
in addition to what box said, you can use thomthom’s free cleanup³ plugin (you’d also need to install tt_lib) that will automatically reduce edges, so you don’t have to investigate should this scenario be reproduced.
You can find it in the extension warehouse
Nice work, but the question is how do you found the two extra segments, how you figured out that edges have two segments. I think you didn’t press individually to each edges so please tell me your method to find them.
Thanks Paul.millet for thomthom’s plugin suggestion, but the question is exactly how can I manually investigate the component and find the extra elements!
One simple way to find divided edges as in your example is to temporarily turn on Endpoints in the style and look for places where endpoints should not exist. Here you can see an endpoint in the middle of the bottom edge.
After fixing it as Box showed, no endpoint there.
Ok, I get it but my endpoints are 9 before I delete the two extra points and the same after. Why the number of them don’t change/decrease?
In the image you uploaded the endpoints are four, not nine, and the profile number is only one not two like mine, why?
That’s not a count of the number of endpoints. It’s telling you the size of them.
Oh yeah, thank for explanation.
So where can I see my endpoints numbers or I need a plugin?
There isn’t a way that I know of. I suppose you could use some extension to put a guideline point at every intersection and then select all the guide points and look at the count in Entity Info. But, what’s the point? How will knowing how many endpoints you have help you in your modeling?
well by hand, you could use Euler’s polyhedron formula
off course, that’s under the assumption that your model is a clean solid, no open faces, no extra edges…
Vertices - Edges + Faces = 2
therefore
Vertices = 2 + Edges - Faces.
in sketchup you can select all then deselect faces or edges. so you can find out both values and get the vertices count from there.
very nice trick, thanks! 
p.s. the above X link don’t work for me, but this x.com think is the same
