Feature Request (Sketch Timeline)

[14gmathieson]

Hello!

It'd be really useful to have a proper timeline in sketches - the number of times I've had to re-do elements or an entire sketch just because there's either no method or no method that I'm aware of for changing certain features further back in the process. Please consider adding this functionality.

Thank you,

George

You will need way more detail in your submission to show why it is needed.

When you finish a sketch, it is what it is,

Edit it if it is incorrect or missing detail.

For each Fusion session, between saves at least, you have the Undo / Redo functions to utilise, and address in your submission.

For new people - it is recommended one sketch per feature, to keep things simple to understand.

Okay, so I think it'd be important to outline my workflow to help you understand.

The biggest benefit to using Fusion - in my opinion - is the ease of transferring ideas from our minds to our computer. They've done an excellent job so far of making feel as natural and fluid as possible, but obviously there's still ways to improve this. Everyone thinks differently when realising 3D shapes - and again when putting them into CAD software. 

The way that works best for me is sketching the features of the overall shape in 2D then extruding and intersecting as needed to form the 3D shape. The more I can fit into a single sketch, the better (this also helps in reducing timeline clutter). I'm not saying this is what I do for the entirety of the process, but it's certainly my initial step; I'm sure there are other ways that work better for other people. 

For this reason, many of my "steps" in what would be the main timeline are condensed into a single sketch. This is all good and well, but later in the design when I need to change something fundamental, I'll go back into that sketch and alter it - making sure not to cause any later steps to fail when returning to the latest point.

However, all too often, I'll go into a sketch and attempt to move a single line and then find the entire sketch to alter shape drastically (presumably due to hidden constraints). I have no choice but to then redraw that line, for example, which fundamentally redefines the shape meaning that a step in the main timeline fails as it no longer recognises that feature as it was. This causes major and cascading consequences for the entire design.

All I suggest is having a collection of steps that can be expanded or hidden in the timeline - not dissimilar to what's seen when creating multiple components from bodies - holding each notable step in the sketch. I know you'll want to suggest just changing my workflow but, as I've already suggested, this isn't a workflow quirk but, instead, a fundamental way if thinking and transferring initial ideas. Fusion should be supportive and compatible with slight differences in the way people think up ideas - especially when it takes little development to include this feature.

Hope this helps?

Hi,

If you insist on packing as much as possible into a sketch, you must expect that this will lead to fatal errors in the design.
The timeline function in sketches does not change this. This tells you nothing about conflict linkages.

This sets off alarm bells! You should always fully constrain sketches so edits are predictable. Also keep sketches as simple as possible, try to avoid patterns and fillets and add them as features in the timeline and with fillets add them as a last step if possible.

Please share an example of your sketches, preferably as an f3d file but a screen grab if you can't share a design.

I will try to do so in a few hours if I get the chance. 

[14gmathieson]

I see your point, but the only reason this way of working is wrong is because of the way Fusion is set up. I'm suggesting a simple feature should be added to allow more variety in workflows - helping to allow people to work in a way that suits their creative methodology. I understand that this isn't a traditional way of approaching 3D CAD, but that shouldn't mean it can't be. If I get time later on, I'll create an example to better illustrate my point.

[14gmathieson]

Okay, so here's a rudimentary example:

I could make the final shape by first sketching one face, creating an offset plane, sketching the end face...

[14gmathieson]

Then creating a loft between the two faces.

[14gmathieson]

What I would usually do, however, is something along the lines of the following:

Create the side profile in a sketch, extrude it to make a 3D object, and intersecting an identical sketch on the perpendicular axis.

[HughesTooling]

I'd say your second method is good apart from not fully constraining your sketches. As long as it's fully constrained any edits would be predictable. I guess this example it a bit too simplified to demonstrate the problems you're running into but really if you learn how to create efficient sketches a lot of your problems will go away. 

Your request has come up a few times before and maybe something like what your after might turn up sometime. But for now learning the skill of creating efficient sketches is your best bet, it does become second nature after a while.😉

One problem I do see with a timeline in sketches would be performance, Fusion's sketcher can bog down now without adding even more overhead.

Here's my recommendation. Move beyond the sketching! Quickly!

The purpose of a sketch in any current, main stream CAD software is to create simple, basic shapes to be refined with solid (or surface) modeling tools. Simple sketches and features instead of sketches.

Trying   to avoid Timeline clutter by cramming as much stuff as possible into a sketches is simply the wrong workflow.

So how does a sketch timeline assist your Lofted block,

both methods are 2 simple (incomplete) sketches.

Others have mentioned not fully defined sketches, so presenting them as an example takes you away from your feature request.

I am with The Whisperer, demo with your problem file, and how a timeline would assist.

My opinion - there are bigger fish to fry for Autodesk.

Might help.....

It is often said that a picture is worth a thousand words.

I might reply that an actual *.f3d file to illustrate is worth a thousand pictures.

I’ll try one more time - can you Attach a *.f3d file here that definitively illustrates the usefulness of your requested enhancement? 

[14gmathieson]

Right, I'm being seriously misunderstood. I'll go and educate myself on defining/completing sketches - if anyone knows a good resource for this please let me know - before coming back here to address the issue (providing I still consider it valid by then).
