introduction
If you've taken certain math courses, you'll remember that a line may be expressed as Y=MX+B. This is an equation for a Straight Line
Splines are complex Lines that may be expressed by a wide variety of equations
Splines are visually controlled with Handles
Handles are imaginary Vectors that extend out of Control Points
You may imagine that a Straight Line has Control Points only at the End-Points with the handle points directed at the opposite end point
If you have the option to use a Line, Arc, or Fillet instead of a Spline, DO IT. Splines should only be used when a Spline is the only entity that will work
Spline Handle Points can be constrained

CONTROLLING SPLINES
CONTROLLING SPLINES
Generally splines will have a Tangency Control point of a sort
The Arrow portion controls the Length
The Diamond controls the Angle
The Dot controls Length/Angle
Once you've manipulated the Control Point, it turns BLUE
If you RMB→Reset the control point it will revert to GREY
It is important to have the fewest number of control points required for the desired Spline
You may RMB Spline→Add Tangency Control OR RMB Tangency Control→Delete to add/remove respectively
Sometimes manipulating the Control Polygon is most effective and should be toggled on via the Spline RMB-Menu
In many cases, you'll want your spline to have Tangency to the entities it is connected to; simply add this relation, but beware it has a 50% chance of inverting itself. To avoid this inversion, try to ensure the Spline has been controlled to appear as close to the desired position as possible prior to adding relation
