Component moving not precise

Jeff is quite correct, in his assessment. You are seeing the effects of "super" micro zooming, where you are at your (and SketchUp's) limit of precision (0.000001)
The points do, actually, share the same endpoint coordinates, but the display of the points don't correspond. This has to do with the order that SketchUp draws the entities. Since you have two groups/components, one gets drawn, then the other. If you had drawn a pentagon, then drawn the hexagon (with no grouping,) the entities would be "connected," and will be drawn, subseqently, adjacent line-after-line, employing the same screen/display location for the shared endpoints.
To demonstrate that this is a display issue, only, you can explode the two, leaving only lines and faces. Do the extreme zoom, and you'll see what appears to be "healing" of the endpoints. Zoom back out, and make the existing (connected) entities into two groups (each face and it's bounding edges.) Extreme zoom-in, again, and you see the "errors" have reappeared.
So, it's not an error in coordinates or precision, it's merely a display issue, when zoomed-in at the limits of precision. (You will note that, at extreme zoom-in, you often can not select any entities, either.)
I can replicate very precise icosahedron/dodecahedron faces/edges, as components, and perform precise rotations, too. I just don't expect them to be accurate to more-than 6 decimals. That said, I've found precision to be excellent, and reproducible, from 1-to-6 decimals.
Other users will confirm that SketchUp can exhibit odd behavior at extremely-small scales. I file this issue under the same category.

Hi,
First... Sorry but i don't speak english very well ! (or... i must say i don't speak english at all !!!!)
When you move one object over another object (the 2 object corners are touching each other) , for exemple, you move a cube#1, selecting a corner and you drop it (move it) until the corner is touching a corner from cube#2, there is no problem... You can zoom at maximum, the 2 corner of the cubes are always at the same point (same place).
Now you repeat the same operation but before you move the cube, you make a group (or component) with each cube... You can move cube#1 (corner from cube#1) on the cube#2 (corner from cube#2) selecting "end of component" or "end of group" to snap... but when you make a zoom at maximum, you see that the 2 corners are not at the same place !!!! The difference is very very small... but you see that the 2 corners are'nt in a same location. I have search for a long time because this "detail" is for me not acceptable...
But... now if you explode the two group (after you have move them) and after that you zoom at the maximum, the 2 corners are NOW in the exact and same location...
Conclusion : when you work with component or group, visually Sketchup can't display the object at the right place... The object (group or component) are in the right place but when you make a big zoom, Sketchup cannot display them correctly...
Sorry... I hope you understand what i mean...
