Hi,
Ok, changing the unitsquare into fullsquare is giving a better result, however it is still not the right drawing. I realise, that in this case probably the use of a vector in this way is not appropriate. — I have changed the drawing into something with rotating the top-line of the rectangle around the corner. If I am correct, then this is the right drawing.
Thank you again for your answer, it made me see the culprit correctly! I hav eno clu ewhat the intended outcome is but here's some code that shows how triangles relate to squares
\startMPpage path p ; p := fullsquare scaled 4cm; path q ; q := fulltriangle rotated -90 sized 4cm; draw p withcolor red ; draw q withcolor green ; draw center p withpen pencircle scaled 3mm withcolor red ; draw center q withpen pencircle scaled 2mm withcolor green ; draw origin withpen pencircle scaled 1mm withcolor white ; draw q shifted (center p - center q) withcolor blue ; \stopMPpage ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------
