Is Snapping To Grid in Photo working at all?

Recommended Posts

I keep trying to draw shapes with grids set and all snapping features turned on, yet nothing ever aligns to a grid. No matter what I do I may as well be drawing with a brush. In the attached image not one single thing is snapping to the visible grid. What do I have to do to get snapping to grid to work? Having implemented grids and snapping in a drawing engine in the past, this is pretty frustrating. I've tried turning things on and off randomly but nothing changes the lack of snappery.

Resizing seems to support a little snapping, but creation seems to not do anything.

You have two snapping items on, pixels and the grid. Turn off the pixels and you'll then be able to only snap to to the grid.

That does not change anything. I've tried all combinations of those options, nothing lets me create objects that snap to grid boundaries. It's as if it only ever snaps to a 1 pix boundary.

Do you see the little coloured dots which show up when you are on a snapping candidate?

Try a restart of Photo by quitting and Clearing User Data. Do this after you have backed up your brushes etc which you have created. Hold down the Control while starting Photo, the Clear User Data dialog window will appear and you can then click Clear.

Are the two documents you gave screen-grabs for in your initial post the same one?
I only ask as the grid doesn’t seem to be the same (or I’m not looking at it correctly). Note where the grid seems to line up with 3000,3500,4000 etc. on the horizontal ruler on the second version but doesn’t on the first.

One more thought, do you have Metal enable for the display (in Preferences > Performance)? I seem to recall there were problems with open GL not working properly.

Same doc, I changed the grid in between from 64 to 256 to make it more obvious; the ruler should not affect how a grid works. Yes I am using Metal. Snapping has never seemed to work since I bought Photo. Resetting cached info for an app should not change how the code works, snapping is clearly a code feature not a data feature.

Note also that setting the same options in Affinity Designer works correctly. I think Photo is just buggy.

Nothing appears when I drag create or resize.

When I have snapping on and set to snap to grid I do get the coloured dots and a jerky jumping size of the rectangle I am drawing. If I have snapping off then nothing appears.

Are you using a mouse, trackpad, graphics pen?

What OS are you using?

Do you have any third party utilities for Mice or keyboard shortcuts installed?

Why is Screen Tolerance = 3? I have 8. It is same in ADe and APh?

Try to enlarge it, depending on the screen size and number of pixels.

Have you tried increasing the Screen tolerance? I find with your settings (Screen tolerance 3, at pretty much any magnification), then it won't snap. Increase the Screen tolerance to around 8 or 12 and see if that helps.

(I'm on Catalina too, 2018 MacBook Pro.)

No idea why it defaulted to 3. Thanks!

You're welcome.

The value of 3 is certainly not the default, this is the mentioned value of 8. Likewise, the default value of Snapping Candidates is not 1. I think you edited these values and changed the input boxes.

It's not terribly useful giving people to many options to mess with.

The options are all useful when you have more experience and understanding, and would be missed by experienced users if they were not provided.

A couple of suggestions: First read the Help or watch the tutorials to see how something should work, and when changing options make changes to a single option at a time, rather than changing a lot of things at one time :)

I think it would be useful for affinity applications, to allow two modes - for beginners and for professionals.
