You can click anywhere in the viewport and drag horizontally to adjust the distance.
Aye! I've discovered that short after I've posted my previous comment. Adjusting the increment is certainly “work in progress”. It is, isn't it?
But what is this? (attached image) I challenge anyone to guess what edges I've beveled.
There are other problems I've detected and I have to find the time to build my case for Support, but I cannot help being the oddball here and ask whether SideFX is taking this seriously.
It seems that it doesn't, after 3-4 versions since they said they'll make Houdini a standard for modeling (paraphrasing, something of the sorts) - a too low hanging fruit, modeling that is, one has to stoop too low to grab it from their so high upper branch.
Lately, I've been busy with pondering about my naivete, as I've praised SideFX regarding the “volatile alignment” tools, as being brilliant and with an XSI DNA in it. Apparently I was half right - it probably has XSI's DNA in it (since Softimage's devs got absorbed into Maya dev team), but it came through Maya as I've recently discovered they're similar. Or maybe I'm mistaken and Autodesk copied SideFX, I don't have a record of change logs for both pieces of software - doubt it.
It's just sad and embarrassing and if some decision making person from SideFX reads this, please repeat this a few times in your mind while you get up from your desk towards the water-cooler: “got to copy XSI, not Maya; got to…”. There are too many people saying XSI was brilliant as far as UX goes, so it can't be a conspiracy or mass delusion. People coming from Max, Maya and wherever. So you might as well copy from there, if you must copy from somewhere.
Or start innovating on this front too. We know you can.
