Hi Aditya, Thank you very much ! That's great indeed, you gave me an elegant solution. One more question, in order for me to understand a little more: when defining a new dotlabel as you do, might it not conflict with the internal definitions of dotlabel in Metafun in some other place? Maybe

Hi all, In Metafun when representing a point I woul dlike to have some dots represented by a square (or even by another scalable symbol): for instance in the following I would like the dot at the point B to be a square: \starttext \startMPcode draw (2cm,3cm) -- (3cm,5cm) ;

Hi Aditya, Thanks for the alternative method, which comes handy if one wishes to extend the straight line by a different amount at either end: \starttext \startMPcode z1 = (1cm,3cm) ; z2 = (5cm, 9cm) ; z3 = 1cm * dir(angle (z2 - z1)) shifted z2 ; z4 = -.5cm*dir(angle(z2 - z1))

Hi, I have a silly question: given two points in the plane z1 = (1cm,3cm) ; z2 = (5cm, 9cm) ; the command draw z1 -- z2 withpen pencircle scaled .5pt ; draws the line segment joining z1 and z2. How could I draw the line segment which goes a little further (say 1cm) than

Hi Hans, One MetaPost feature that I was looking forward to is the ability to create a fill between two shapes. Something like a difference function of two path's. For logos I use the workaround with creating a path alongside the excluded areas but it is always cumbersome. I have briefly
