When creating line objects the Advanced Digitizing window shows you distance (d), angle (a), x coordinate and y coordinate.
To use it, switch on both the Advanced Digitizing panel and toolbar and click the icon for 'Enable advanced digitizing tools' when you are editing
I do not think this is possible in ModelBuilder.
But you could create a model that :
convert the line vertex to point
add XY (and if needed ZM) coordinate to the newly created point
select some of the point
Export a table with the coordinate you're after
