Incorrect dimensions of sketches in drawings

[petermat]

Dimensions of sketches added to design derived drawings do not scale properly if the drawing base view is scaled other than 1:1
This leads to absurdities like a 3" square (sketch) wholly inside a 2" square (base drawing) if the base drawing scale is N:1 where N > 1.

See attached example.

Also the yellow triangle pling that accompanies dimensions between sketch and drawing features is annoying and seems impossible to get rid off. 

Also the inability to type in dimensions for a sketch object is frustrating.

But having the ability to add sketches to drawings is (otherwise) wonderful!

Hi,

Thanks for the feedback, I'm happy to pass it along to the drawings development team.

One thing about Fusion drawings: The "paper" is always 1 : 1. So is the sketch, because it is relative to the "paper", not the drawing view.

For example: 

What if you had a big F size drawing sheet, with views of a dozen parts, each one at a different scale.

• What scale would you expect the sketch to use? (Your answer might help the drawings team design a better experience.)

Regarding the yellow symbols you mention. Can you show an example design or workflow that produces these? They exist typically when the drawing view is in some way out of sync with the dimension, so it's there on purpose. Can you share the workflow that causes this for you?

Thanks,

Phil,

My use of skethes on a drawing is to show things like holdowns, a vice or where interference is to be avoided. So for me the sketch dimensions should always be at the same scale as the part drawing it overlays. However, I appreciate your point about multiple parts. So I suggest the following:

• When entering sketch mode the default scale should be 1:1, but there should be an option to choose the scale.
• All drawing dimensions that anchor to a part drawing should be at the scale of that drawing.
• If a dimension has one anchor to a sketch and the other to a drawing,
• and they have the same scale, use that scale for dimensions, or
• if they have differing scales, offer 1:1 and the two differing scales
• If both anchors are to sketch features the scale should be the sketch scale.

Regarding the yellow symbols there were examples in the file I attached – and below:

They seem to occur whenever a dimension has one anchor on a sketch and the other on a part.  In many of my uses, the dimension is important to show the realtionship between part and the sketched object

What about the inability to type in the size of a sketch object" in a drawing - like one can when sketching in Design mode?

Thanks for the details.

The sketch tools in drawings are not intended to be "drawing" tools for creating accurate machinable parts. They are intended to add a little more flexibility when creating drawing views and annotation, not drawing manufactured items.

[petermat]

Understood - and nothing I do - or intended to convey - was related the sketches being use to define machining.  The ask for being able to enter dimensions of sketch items is simply one of convenience - it's much quicker to type in a couple of digits than to try to get the cursor positioned where it is wanted.

Got it. I guess I did not interpret this correctly?

Hi @petermat ,
I see there are couple of good suggestions and these can be surely reviewed by design team.
Discussing more about yellow badge shown in image, it seems it works how it's intended.
It signifies that dimension references has been suppressed or deleted or not associated to one type of source.

So, user prompted to re-associate dimension or delete it, by this yellow badge.

Additionally: User is prompted about these disassociation annotations, while output drawing command.

To get desired results like true association (dimension should update with respect to source) there should be no association issue/yellow badge.

About sketch tool - someone can create a dimension purely associated with sketch and dimensions will be automatically updated after editing of sketch.

Thanks & regards

Amit,

OK so the yellow badge is working as intended. and I can certainly see that for some users a "dimension references . .  [that is]  not associated to one type of source." could well be a mistake which should be flagged to he user. However, in my case often the whole point is to identify - dimension - where a part has to be placed in relation to a sketched fixture to avoid conflict. Perhaps a way of 'accepting' flagged situations, so the flag went away in the output to pdf?

Hi @petermat ,

The flag remains in drawings,

the prompt helps user to expect the changes (if any) in output file.

User can still continue with Output/Print commands.

Thanks & regards

Amit,

I understand the flag remains in drawings. I also understand that this is designed behavior and appropriate for some situations. However if the user intends to dimension between a part and a sketch and knows that this dimension - while currently correct - will not be updated, then the flag is totally inappropriate. The user should be allowed to delete it when they consider it irrelevant and misleading. Currently I am screen printing the drawing, and then editing the flag out to produce a usable drawing.

This took me a few minutes to understand, but it's also misleading to create a yellow flag when I simply used a geometric circle crosshairs provided by Fusion!  I then use those crosshairs (instead of right clicking and selecting center... really?) and then I get a yellow flag.

(also I prefer to use the cross hairs so that the dimension line isn't covering up the dashed center line.  Again.. professionalism is generally lacking on the 2D drawing part of Fusion)

Come on...
