Sorry, couldn't resist, this argument has been in the cad world for a while, 'history' or 'history free' that is the question.

Yahsoo JBT,

I've been using history based software at work for several years now and for the designs we do, you need it, because of amount of customer changes involved.
In a large organisation you can't afford to redo things from scratch, that's why the investment is made in high end cad, but that doesn't say it's easy
to use, sometimes history modeling can be a pain in the neck, you can't just model willy nilly and get a result you have to plan your modeling as you go,
you must think about the history 10 steps ahead so you have a sound model that will stick together after you make changes later.
I try to model with the least amount of features in the history tree as possible because the more features involved the more likely something will 'fall off' and if
more features 'fall off' the longer it takes to find the problem and then edit them.

I bought MoI for home use only because of how it is now, quick, accurate and a breath of fresh air from my day to day job.
For conceptual work it's fantastic, I thought I'd give a go on a real job from home that needed to be accurate and it didn't feel like work, but, you still need to
do some up front planning.

> and.... yes, it happens to me very often to change my mind about something I model.

That's where the planning comes into it, you have to see a few steps ahead before you commit a command, in the case I mentioned above I couldn't afford to change my mind,
but we are all human and we do change our mind, that's why before I commited to a boolean or trim I would incremental save at that point 'ALT-S' I was up to about 22 saves when I finished the model.
And there are times when I'd just redo the model from scatch in MoI because it's so quick and easy to model with.

Don't get me wrong, I'd like some more powerful history stuff in MoI too, but if you plan ahead, in your head, we can get by very easily, even more so when Michael starts on the object organisation stuff.

Just one more thing, just 2 days ago, I got back from a new release seminar for the software we use at work and it was a huge hyp about a brand new feature and breakthrough for this version release, it turned out to be they now included the option of 'history', 'history free' or a combanation of both type of modeling, pretty powerful stuff sort of push pull stuff a bit like Spaceclaim that was mentioned in the forum somewhere.

Any way I thought I'd share my experience on the subject.

Cheers
