Bullnose
Under what starting criteria?
Would CapEnd.lsp >here< do it for you, using its Arc option? It wants two parallel ends of anything with linearity that align correctly for adding the half-circle Arc to finish them off:

The reason I ask is that what you're starting with would have a huge effect on how the bullnosing would be accomplished.
You might, for example, have something with side Lines already drawn [such as at the full depth of parking spaces], and you want the Arc drawn to connect the ends but you also want the Lines shortened so that the extent of the Arc bulge matches the extent in that direction of the original Lines [i.e. the depth of the parking spaces]:
That could be accomplished with a modification of the CapEnd code [and presumably at the same time a reduction of it to only the Arc mode, eliminating its other options].
Or you might have something like a Polyline with a squared-off end that you want rounded at the same extent:
which would require an entirely different approach [change vertex locations and the bulge factor for that segment].

EDIT: But if you download that, at least change the (command) function in the *error* handler to (command-s) for newer-than-2015± versions, or better yet use the attached UPDATED CapEnd.lsp, which does that Undo begin/end thing in the "better" way, and has a few other little refinements [mostly in the handling of variables]. [The website in the link is no longer accepting submissions, so I can't update the file there, but now you don't need the link anyway.]

@john.uhden : Are you aware that the same can be done, if the two lines are LINE entities specifically, with an ordinary FILLET command? When they're parallel it completely ignores the Fillet Radius setting but suits it to the spacing between them. And unlike CapEnd, it does not require the ends to be aligned, but it keeps the length of the first Line picked, and adjusts the length of the second -- here, if you pick the left Line first you will get the right-side result:
But unlike CapEnd, that doesn't work if they're Polylines, Arcs, etc.

So does "EXACTLY!" in reply to Message 8 mean that Fillet does exactly what you need, and you don't need any custom routine? Or does it mean the problem is exactly that it works with Line entities only, and you do need something for other object types? Or does it mean the problem is exactly that, while Fillet will work with non-aligned Line ends, CapEnd.lsp won't, but you need it to, for use with other-than-Line object types that Fillet can't work with? Or ... ?
This may save all the heart ache its supplied as a sample with CIV3D does what you want plus way more.
