Incremental move?

[Anonymous]

Hi all, I have incremental move set to .25mm with Fixed selected and not adaptive. My grid is currently in 1mm increments. Snap to grid is selected. But I'm not snapping to .25mm increments. Am I not understanding incremental move? Is there some sort of setting box I didn't check? I will kudo anyone with a solution or explanation on why incremental move is even there or if this is a bug.  Thanks

Hi,

You need to check the incremental box, and then open up the Grid Settings and choose fixed, and make sure that the Subdivisions are 1

Here is a screencast about it

Kind regards, Saeed

Thanks for responding Saeed.. Unfortunately I want to see My major grid lines with a darker contrast from my minor grid lines and have my incremental move .25mm not from grid to grid but within a hidden grid that you cannot see just like a program I use to use called Rhino 3D.  For example... I like to see my major grid line at 5mm apart with the minor grid lines at 1mm, but... the snap movements move every .25mm within a 1mm grid square..              If I set it up like you have shown I don't want to see the .25mm grid lines, thats just too much mess going on in the work space and it's hard to count things in 5mm increments.   Rhino has a much better setup.  Or atleast they Fusion 360 needs to be more accurate on its incremental move meaning/interpretation..

@Anonymous It is not possible to do what you are after. The snap in the sketch environment will snap to the grid settings. In this case you would want to set up your major grid lines at 5 mm and have 20 subdivisions in order to snap your sketch geometry every .25 mm. 

The incremental move helps with things like the press/pull, shape primitives, or move command in 3D operations. Incremental move doesn't really have much to do with sketching (unless you're using the move command). I'm not sure about others, but I don't generally use the incremental move because I like the feel when Fusion is a bit more free form. However, that's just my personal preference.

I would highlight that the real power in Fusion 360 is that sketches can be driven parametrically by dimensions and constraints. You can even use parameters to update sketch dimensions to quickly modify a sketch. While it may be helpful when initially drawing something to use the snaps, there is a lot of utility to being able to edit one dimension and based upon the relationships created by sketch constraints, drive or modify a sketch profile.

Really dimensions and sketch constraints are the mechanisms you should probably use to make sure that sketch geometry is the exact size. That is a rule of thumb and not true in every case. I'm not trying to preach that you "must" use the tool. The tool should be flexible and accommodating. I'm hope this explanation highlights the design intent and difference between other applications and Fusion's constraint based sketch environment.

If there is a workflow you're struggling with, perhaps you could record an Autodesk Screencast of the workflow to highlight what you're trying to accomplish? With this information, I may be able to make some suggestions that could help make it less painful. 

I hope this helps. Please let me know if you have any questions.

Thanks,
