While I am running OpenRail 2021 R1, this is just linework.
Is there a way, either a dgnlib edit, or a vba function, that would allow me to input, for example "d10" instead of converting to radius in "circular fillet"?
I know I can do it with geometry, but when doing quick concepts, it is quicker to just use dumb lines

Oh yes. I am in the land of "freedom units".
Jon Summers said:So when you write 'd10' does that mean R=50/(sin(10/2))?
Exactly. Should get 573.6857'

Is there a fixed number of DXX values, or is it arbitrary? That is, do you write D5, D10, D15... or can you specify, for example, D17?

Arbitrary. Can be whatever you'd like, though the majority of the time they are kept to increments of 15 minutes. Attached is the table we use.

Couple things. Does not rail degree of curve and road degree of curve differ? Never designed any rails, but I assume most any curve has transitions or spirals at both ends. Though not exact, I think for simple conceptual linework you'd be better off just remembering the radius for a 1° curve then allowing the dialog to "do the math" using the radius field. But I would think OpenRail software would incorporate just such a tool as you describe to help with preliminary/conceptual design.

Just the difference between arc and chord curve definition.

On mainline track, yes. Yards usually don't due to such slow speeds.

When creating geometry, yes. Doing just basic linework, not as far as I know
