[Closed] How can I measure the distance b2in objects?

I try to find some tools in Rhinoceros to show me the minimum distance between the objects but there isn´t. Only Thinckness Analysis.

I need this to analyse STL files. I had some troubles when put the 3D files to Rapid Protopype, and this Analyse Tool helps a lot.

What I spect is:

Put in parameters the max and min distance
Select the objects (2 or more)
Click to analyse
And show in 3D viewport the 3D colored with the respective color-value

Some light about it?

Thank you.
