rocthered Posted November 4, 2022 Share Posted November 4, 2022 Hi everyone, I have an annoying problem while using affinity designer and publisher. I use them to arrange my figures a lot, just to make them aligned. I think the fastest way to do this is snapping. However, when I enable snapping to spread, even with force whole pixel movement on, I got this strange problem: sometimes when it seems to be snapped, there is actually a 0.1 pixel difference. See below screen shot and the numbers in red rectangle. I tried to snap the figure to the corner of the spread, and both 0 and 0.1 px can make it looks like snapped. I have to be very careful to make it snap to 0 px. I know I can type a number. But it is not as convenient as snapping. I am wondering if this is meant to be? And is it possible to correct it somehow? Thanks! Quote Link to comment Share on other sites More sharing options...

It is a recipe for such issues. when using snapping, either snap to whole pixel positions, or to grid, or to other objects. You need to choose one, don’t activate multiple at once. this advice is for beginners. Snapping is extremely powerful, unfortunately heavily loaded with so much options that it is hard to master. Try to activate only the smallest possible set, save as preset, and choose one preset specific for every use case.

However it still happens, with only one snap option is on: snap to spreads. Did I understand you correctly? Quote Link to comment Share on other sites More sharing options...
thomaso Posted November 5, 2022 Share Posted November 5, 2022 Had you moved the ruler's origin? Just in case, double click its intersection (unit) to reset to 0/0. Quote macOS 10.14.6 | MacBookPro Retina 15" | Eizo 27" | Affinity V1 Link to comment Share on other sites More sharing options...

Hi @thomaso, The spread origin is 0,0, if it is what you meant. Actually, currently -0.1, and 0 px both look like snapped, so not very likely related to ruler..

I also know such inaccuracies. The smaller an object is on the drawing surface, the more likely it is to snap into place "crookedly". A larger zoom level can then help. Or manual/numerical alignment.

I tried this and didn't help. But to be clear, the problem is in snapping to spread, not to object. I misunderstood the problem previously.

Then it is an issue with either the ruler origin or "just" a ruler inaccuracy. With other words: it does not snap to a wrong position but rather "just" reports wrong position values. Test: 1. Untick the snapping force and full pixel options. 2. Create somewhere on the page two rectangles: numerically & without decimals. 3. Let one drag-snap to the other (side by side). 4. Select both and let one snap at the spread origin. 5. Result: Does each of them report the 0.1 px decimal?

I tried to duplicate a rectangle, snap one to the spread corner with 0, and another with -0.1. When I zoom, I can see the difference like below screen snot. I think the problem is both 0 and -0.1 can snap: I will try what you suggested. Thanks! Quote Link to comment Share on other sites More sharing options...

What x/y values does the Transform panel report if you select only that object which is not placed at the spread edge? Just in case: What are your bleed settings?

Turned out my bleed was set as 0.1 for all four positions. Not sure why it's like that. I don't remember I ever set it that way... Thanks a lot! After changing them to 0 the problem seems to be fixed! thomaso and Old Bruce 2 Quote Link to comment Share on other sites More sharing options...
