Automatically accept Driven Dimension

[DavidVoxon]

Hello,

It's often handy to see derived dimensions on sketches, which Fusion calls a Driven Dimension.

However, it's really annoying to have to keep accepting the "Adding this dimension will over-constrain the sketch. Choose OK to create a Driven Dimension." dialogue.

I know the dimension value is derived, but I still want to see it!

Is there a setting that disables this warning dialogue?

I do not know of any such setting.

Hi,

The warning makes sense in principle.
You have the option to ignore it.

No - you Must acknowledge it, every time you use it, 

needs a Don't show me again, Tick Box.

100% agree, its an incredibly annoying message. Reminds me of the "You have clicked OK, please click OK to continue" messages that seemed to plague early 2000s software.

I don't see it that way!

I agree with @g-andresen here - it is important information that a dimension you are trying to create cannot be created as a driving dimension - it means that this geometry is already fully constrained.  Silently creating this as a driven dimension is, IMO, omitting valuable information from the user.  I'm surprised that people are creating large numbers of driven dimensions.  Would be interested to know the workflow for that.

Re: essential dialogue.

Fully constrained elements change colour; driven dimensions are enclosed in parenthesis; driven dimensions cannot be edited. I'd say Fusion already indicates the dimension is driven three times over, so why can't I have the option to not be held up accepting the fourth? A "don't tell me again" checkbox means people who haven't yet developed an understanding can leave it unticked, while people who just want to get on with their job can.

As to workflows, the prompting case here was creating an electronics footprint for an for an existing mechanical part. I wasn't setting any dimensions; driven dimensions are a quick way to make visible a whole view's worth of dimensions—relative to an arbitrary centerpoint to boot. (But it did mean accepting a dialogue after every single action!)

I often use driven dimensions as a check; they're particularly when using parametrically defined dimensions, they're also very informative when editing a "linked context" part away on it's own, and so on.

thanks for the explanation, @DavidVoxon , it helps me understand the request.

How about the ability to reference driven dimensions? all the other parametric design suites offer this feature ie Solidworks, Inventor. I believe it's been requested over and over but Autodesk has continually turned a deaf ear. Thanks,

[jeff_strater]

the "deaf ear" is hearing.  This project is underway.  If you want more details, there is an entire thread about why this is difficult, if you are interested.

[DavidVoxon]

Parametising a driven dimension is a feature many would dearly love to see (myself included), but it a distinct issue from this one.

[davebYYPCU]

I use them for testing formula in parameter tables, (usually temporary, but you still have to select ok, to place each one of them).
