I now have access to 2025.
Where I have the Snap tool available to me.
I'm not smart enough to work it out.
Could you please tell me how you did it starting from the Star Point.skp from my original post?

Hi Rich,
Any chance you could use that snap for the other 4 points like this:

No insult intended.
I'm trying to see how off the finished star is.
You can see that last snap (Labeled Right) is off.
Lets say my 2mm if perfectly joined with the other 4 points.
But I can't get the points left and right in Sketchup.
So if they are already off on the first snap then multiplied by 10 to get the total discrepency.
