How precisely are planes assembled ?

I'm curious as how to calculate or estimate the effects of imprecise construction / design.

I'm looking for the info for model plane construction, but it could also be used for a homebuilt ... one of these days

Take some extreme examples.

Wingpan 30' . Chord 4'

1) Left wing span is only 29' ..or 28' ...20 .. etc

When does the plane become unflyable ?

2) Back to normal, but left wing chord is now 3.9' 3.5' .. 2' ...

3) Normal but, left wing is further forward/back along the fuselage than the right wing, offset by 1mm, 1cm, 1meter

4) Normal but, left wing has more/less dihedral than the right wing. 1, 5, 10 degrees

5) Normal but left wing has more/less sweep than right


5) Same things for the stab. E.g. left stab span is less than right, ... left stab chord less than right

I'd imagine there could be some heavy math involved, if you know it and feel inclined, lay it on me
