Is there a way of controlling which types of sketch relations are added automatically, and which are not? It seems you either have to have them all on or all off. I prefer to define lines to be parallel or perpendicular rather than horizontal/vertical, and it irks me no end that I have to manually delete the horiz/vert relations. In I-Deas, there is an RMB function that pops up a window with tick boxes for which relations you want it to create or recognise (the latter being a bit like the mates option "use for positioning only"). I'm on SW2004 - has it been improved since then? Do people feel it would be worth an enhancement request? Regards, John Harland
