Line that is fixed distance from another line (not an equidistant!)

Good day,

I have encountered a situation where I need to draw a boundary of a protected area fixed distance from an object (60m). Problem is that there are corners in the complex polyline, which means that in order to draw a line fixed distance away from vertices I'm going to need to draw arcs, as illustrated in green on a square below (not an equidistant in red! Corners are further away than required). Is there an AutoCAD feature for this or maybe a LISP? I can't imagine that manually drawing arcs for the 1000+ vertices is an optimal solution. Due to language I don't even know how to name this problem in order to search for it properly.

Any help with this is greatly appreciated!

Nothing built-in does that. Sorry.

I'm a little surprised to have to contradict a Community Legend, but yes, you can do that, and with a built-in setting.  Set the OFFSETGAPTYPE System Variable to 1.  Then OFFSET does this, directly:

@Kent1Cooper Excellent solution as always and a reminder of a tool long forgotten.

Excellent! Thank you a lot Kent! One more cool system variable to write down.
