You are both very kind, yes as mentioned at the beginning it is questionable to be a traditional 'drawing' as the extrude tool did it for all objects. If that looks beautiful then first of all in Xara someones did a great job which renders such in a .xar file with 527 Kbyte, which so contains 10 pages and 4 from those are on three layers for the views and each with a chess table containing 32 figures plus the clock.

In my opinion there has to be a lot of opportunity in the Extrude tool + animation combo, because the extrudes have this small file size and that is usually key parameter at animations to keep it low.
