symbols (constraints?) unclear and how to discover ?

[dave_g_martin]

 

Newbie here so be kind !!  I recognise some constraint symbols but what do I make of these two?

These are enlarged compared to the tiny versions on my screen, so at best they are difficult to even read.

Is there a nice catalog of these as a visual reference somewhere?  Have searched hard and not found much.

Thanks.

Welcome!  I found this in the Fusion Help documentation, I hope it helps.  🙂

Nice one, thank you.

However I don't see either of my 2 symbols there.

So am hoping someone can recognise them for me?

the one on the right in that image is "coincident" - most likely the point has been constrained to be coincident to the line.   If you hover over it, Fusion will highlight the affected primitives.  The one on the left is "projected", meaning that the geometry in question is referring to other geometry in the model (usually from the Project command to project model geometry into a sketch).

[dave_g_martin]

Thanks.  The "coincident" one however looks unlike the one here: https://help.autodesk.com/view/fusion360/ENU/?guid=SKT-CONSTRAINTS

How is a person (newbie) supposed to know or find out what you have just told me?

And thanks for the "projection" - there is indeed one - but where do I discover that symbol?  Yes there's something similar here: https://help.autodesk.com/view/fusion360/ENU/?guid=SKT-SKETCH-CREATE-PROJECT-INCLUDE  but once again how (without your help) could I really know?

The attached Fusion webpage showing the Coincident Sketch Constraint is identical to the one you see on your sketch.  You must remember your model sketch may be turned on the axis so the symbol is upside down and reversed.

Sorry to be picky, but when your learning this stuff, to be told that a colored (red/green-grey) symbol that is made of straight lines is the SAME (you said "identical") as one that's clearly two hollowed-out grey arrows is straining things.   Presumably Autodesk had a reason for drawing the coincident symbol like that (colored etc), so why doesn't it match what I see?
