Placing spheres on knots/vertices

 From:  martin_8bits (MARTIN_ST)
Hey guys, how is it going.
My name is Martin and this is my 1st post on the forum, however I've been a silent observer for more 3 years.
This community is absolutely stunning.

My main background is 3D CAD (Solid Edge/Moi3D), besides that I have basic knowledge on polygonal modelling (3D Coat/Cinema4D)
I checked the search option but I couldn't find an appropriate answer for my design problem.

Okay here we go. What I want to achieve is ...
1. I want to place spheres on all knots/vertices of a polygonal net automatically (see image).
2. The dimension (radius/diameter) of each sphere shall be defined by a parametric value, if possible stored in the same file like the polygonal mesh/net.

So my question is, do you know a script/routine to realize an automated placing of parametric spheres (or other objects) on knots/vertices?
Doing that manually for few objects is not a big deal, while having thousands of knots/vercities this will become impossible.
I know that there is a script from the one and only Max Smirnov (SMIRNOV), however as I know it is made soley for distributing objects on spheres equaly.
Thank you so much for your help guys, and have a great weekend.
