Grid dissapears

[hato54]

Some time when I working the grid dissapears, why?

Now when I try to o insert the printed screen I get "Sorry, unable to complete the action you requested."

Hi Martin,

Thanks for your reply. I am sorry I forgot to add some keywords when explaining the snap to grid issue. Actually what I mean is: 

Currently the design only allows user to snap to grid inside sketch enviroment while dragging sketch objects. Actually the grid outside the sketch is another grid called layout grid, it's different with sketch grid. Maybe allow user to drag sketch objects to snap to layout grid doesn't make too much sense.

You also mentioned many good points about dynamic grid implementation and some optimization for grid settings. I have asked our developer to take a look at them and evaluate whether we can make some improvements here.

Thanks again for your valuable feedback!

Regards,

Frank

Hi Frank,

so we obviously misunderstood each other. I meant that sketch elements are sometimes (especially when the grid in Infinity Pool is not visible outside of the object - see figure 02 in my earlier post) not snapping to the grid inside sketch mode. With "outside" I meant outside of the objects current spatial boundaries (-> figure 02).

I got your point, that snapping sketch elements outside of sketch mode to the layout grid wouldn't make much sense, because sketch elements have to be edited inside sketch mode.

I fully agree here, but why is it then possible to drag sketch element outside of the sketch mode at all?

You can ruin your sketch when you manipulate elements like vertexes inside layout mode because you have no guidance - not even visible snapping. Sure, snapping to the layout grid would move the vertex (or element) in some circumstances far away from its origin. But it seems to me, that there is some kind of snapping going on in layout mode without being visible to the user. So I think it makes sense to disallow sketch-element manipulation in layout mode completely (and add some more power for rearrangement of whole sketches here! 😛 ).

Thanks,
Martin

Martin,

In parametric modeling, I never rely on the grid for final position. I apply dimensions and constraints to my sketches and drive the sketches parametrically. With one exception: design phase. When I'm in design phase the skech may not be completely fixed.

When the sketch is visible and you are not editing it in Sketch mode it's extremely convenient to drag the sketch a little, or edit the dimensions, and see an instant update to the 3D model. If I had to enter the sketch via editing the timeline node, all the downstream features would disappear because they haven't been created yet!

You can see sketch dimensions and edit the sketch from the model environment by turning on sketch visibility, and also by right click on the sketch node and pick Show Dimensions.

Here is a demo of it:

Hi Phil,

I understand the way it works, but it is (IMHO!!!)...

a) not perfectly implemented, because there is hidden behavior (snapping without visual reference),

b) parametric modelling is IMHO far away of being production ready yet, and

c) it is not my kind of favorite workflow.

To a): It may be helpful if there would be an option to automatically turn on visualization of the underlying construction plane as soon as you drag elements of a sketch in layout mode. A grid could be rendered on this plane, visualizing the snapping actions more clearly.

To b): See for example http://forums.autodesk.com/t5/fusion-360-ideastation-request-a/parameters-dialog-not-blocking/idi-p/...

On the one hand you say you want to see changes directly reflecting the entire design, on the other hand it is hard to do so using the current parametric approach (if you like to work with parameters during the whole process) IMHO.

To c): I like to design my models as precise as possible right from the start but I'm not a fan of tools like SCAD where you have to "program" your design (as Computer Scientist I come to the conclusion that end-users should never ever be forced to go through the struggle of bending a computer system programmatically). My designs are born inside my mind and often I have them mentally in a nearly production ready state. So I need Fusion 360 mainly to transfer the design from my head into a more "physical" state. I am also able to imagine on-the-fly ideas very good "virtually" so I don't need to push things around in Fusion 360 in a rule of thumb manner. Therefor I like to work with sketches and build a precise model visually with all the snapping and constraining. Binding aspects to parametric values is a bonus for me that allows my to e.g. building variants of products more quickly by changing a few numbers, but it is not as I would like it to be yet (see point b).

Just my two cents! 🙂
