Entering angles always in degrees.

If you combine work in different angle units (e.g. degrees and grades), you will probably need to setup your macros and LISP applications so that they use angles in a common, consistent format - in degrees, or alternatively in degrees, minutes and seconds.

By default, relative coordinates are entered as:

@length< angle

which counts with the angle value in the currently set angle units - if you switch to grades or radians, this format will no longer work.

Therefore use a special coordinate format:

@length<< angle

which always uses angles entered in degrees (even when you have e.g. grades as current angle units).

Another option - allowing to enter angles also in surveying minutes and seconds - is the format:

@length< angledminutes'seconds"

giving e.g.:

@500<45d15'25"
@500<45d

This format interprets the angles always in degrees. Similarly you can force entering grades (100g) or radians (1.5r) wherever AutoCAD prompts for angles.
