Is it possible to edit or change a bar from 10 series to 15 series?
Yes, not only 10 to 15 series but also any fractional extrusion to any metric extrusion or vice versa. One important thing you must keep in mind is when you edit any extrusion you will erase any Secondary Machining operations on that bar. Primary Machining: Machining performed on the bar before it is inserted into the drawing (Taps, Miter cuts, custom 45-degree supports…) Secondary Machining: Machining performed on the bar after it has been inserted into the drawing.
