Design History Uses?

[Anonymous]

 I don't really understand why we need to turn design history off before editing. I looked it up and it said design history prevented you from editing components, but as far as I can tell, I can edit them while history is on.

Where did you read, or hear that the design history has to be turned off for editing ?

That is total nonsense 😉

The whole, purpose of the design history is to record all the steps, so editing is easier!

So in one of the video lessons on the Autodesk site, why does the teacher
specifically say to turn off history before he goes through the tutorial,
and then turn it back on at the end? The way he did it implied that it was
something you had to do.

I'd be grateful if you could provide a link to that tutorial.

Sounds like Direct Modelling and imported designs - special circumstances, not the norm.

He doesn't really explain why he turned off history, and it seems like it only makes things difficult, which is why I was confused.

So even in these circumstances, why is it important to turn off history?

I can see that this is confusing for a new user.

In more complex models and assemblies the timeline can become quite long and complex and edits can take quite some tome to re-calculate.

Also  when a design is more exploratory and is developed more or less on the fly it can be very liberating to work without a timeline, because there are no inherent dependencies between sketches and  sketches and features and between components. There are no timeline features that fail because a reference is broken.

This might sound a little abstract but it will become clear once you have some practice.

That is a deep subject, that I am not going to buy in to it, other than to say,  someone has to demo that it exists, 

Direct Modelling suits specific purposes, as he mentioned,

Concepting and modelling on objects imported without history are a couple,  

While he didn't say much, there are functions that are, or are not, available in both environments, 

Turning off history is a one way street, you can't bring it back, without opening an old version and promoting it.

(he said, "We don't need it" for his demo, that was true)  your confused, I won't do it.

I am a history modeller, I want to keep the timeline, and edit as I go, I am familiar with it,

you could get all the same results by editing the sketch / feature in the history version.  

So even in these circumstances, why is it important to turn off history?  

Some functionality changes in each area, he needs the DM functions.

My Opinion: His actions would break the timeline, so delete it before it breaks.

Might help.....
