While I can get the desired result which a filled path I'm looking for a solution where I have to set fewer control points. Draw the paths two grid squares sorter and at each end draw a “dot” which is a triangle of the right direction and shading?

So your first line

draw (1,7) -- (7,7) ;

becomes

triangle_dot_bottom_right_fill (1,7) ; draw (2,6) ; triangle_dot_bottom_left_fill (7,7) ;

If there are load of them then it might be easier to write a macro to walk the (1,7) — (7,7) path and insert “dots” at the changes of direction.

I had this in my mind but wasn't sure if this is the best solution. Using a macro to create the line is a must here but I have to think how to set which delimiters for the line should be used (using different macros for each variation or passing the shape as argument). BTW: Use && to connect the parts of the line to avoid graphical errors in your pdf viewer. \startMPpage[offset=1pt] pickup pensquare scaled 1 ; draw (0,0) ; draw (1,0) ; draw (0,2) && (1,2) ; \stopMPpage Wolfgang
