Sure.Use plain language then.
If you are drawing a 10' radius circle around an object or person the 10' radius circle should be centered on the object or person. You should measure from the center point of the person or object. Very straightforwardIf I draw a 10' radius around an (object or person), do I measure from inside the object or person, or outside of the object or person?
For D&D the typical case is a medium or small size person who will comfortably fit completely within a five foot radius circle. There is no problem with the typical case. It only becomes an issue with corner case NPC types of things like the gargantuan dragon casters.Natural language suggests the 10' radius is drawn from the outside of the object or person, seeing as it avoids the absurdity of a 10 radius around something that is bigger than 20' across, not have a 10' radius around them, but instead have the 10' circle be wholly inside of them.
If I was given written instructions to do so and could not clarify your actual intent I would infer that you mistakenly said 10' radius and meant a line 10 feet away from the house on all sides. Which wouldn't be a circle or a 10' radius.Like assume I (right here and now) instruct you to go away and draw for me a '10' radius around your house'.
Using plain natural language, do you then draw a 10' radius circle inside your house, or around the outside of it?
If the instruction however was to "draw a 10' radius around a box" I would assume you probably meant draw a 10' radius circle centered on the box and not a line that was mostly oval to conform to the shape of the box and a little bigger than a 10' radius circle, though both are possible intents from the imprecise phrasing.
