I mentioned the PCB auto-router in my earlier email, but when talking about rendering speed, I was just talking about how long it takes for PCB to draw a screen-update whilst manually editing the board. You and Bob seem to have thought I was concerned about rendering speed _during_ auto-routing. You still need to look at the auto-router results, even if you don't care about the intermediate steps ;) >From Bob's comments, it seems that perhaps Altium isn't as polished as I've imagined it is. There will still be momentum behind it though, due to: Tool familiarity amongst the designers The designers already bought Altium at some point Existing symbols / schematics which can be reused Production tested and optimised footprints > Belief more than logic seems to be what moves people to choose proprietary > over open tools.
