Proportionally editing an object using a given/exact angle I can proportionally edit an object (see animation below) but if I want to alter an object to have an angle of 63.45 how can I go about calculating/doing this (I'm testing parameters/limits/tolerances for a 3D printer).
The measure tools are just giving a ball park range. I'm trying to be more exact and would like to type in the exact value needed to get the desired angle.

First, make yourself aware of the trigonometrical relations.
$height =  tan(\alpha) = tan(63°)$
In python you can express this as
tan(radians(63))

This is the desired height. Add a cylinder, select the top edge loop and type the equation into the Z field. Upon pressing enter, the value will automatically be calculated.

Scale the top edge loop to 0, add a half sphere, add appropriate loop cuts if necessary, then merge the top circle into a single vertex.
