AFFINITY Designer. The problem of gaps in cracks when dividing shapes

[gaegury]

 

This is using Google Translate in Korean, so the context may be awkward

I am using the latest version of the program on Windows 32bit. We are testing ahead of our purchase.

1 Draw a rectangle with the shape tool.
2. Draw a rectangle with the Pen tool.
3. Select two shapes and click the divide button
The result is not curved or sometimes there is a gap.

Can confirm this issue on macOS as well. It only happens when objects are relatively small in size. And on bigger objects result is good.

I tested with Force Pixel Alignment setting on and off. Turned Snapping on and off.

Seems like there's a precision or rounding issue which prevents small objects from being calculated and rendered correctly when using boolean tools.

Hello @gaegury and welcome to the forums.

It works as expected for me.
My test settings:
Document for web: 1080 x 1080, 144 dpi, cmyk

I'm on Windows 10 64bit.

@Komatös Try scaling your group so it is <10px width and height, for example. And then try Divide again.

Thank you both.
The size I tested was a very small size, and the larger the size, the more stable it seems to be divided.
However, unfortunately, if you add again after division, it will not be added completely and a border will remain.

If you scale both to the same width and high, the elipse will go to an light oval.

Thanks for correction @Komatös

What I wanted to say is that you need to make your layers smaller in order to see the issue. Largest of those values should be less than 10px or so.

Hi @gaegury I have reproduced this issue using a tiny shape of under 10px in both Affinity Designer & Illustrator. I also created the shapes at around 560px, divided them and them scaled them down and the issue wasn't there. 

I think when working on very tiny files it's worth having another working area where you can make the shapes larger first. I do this sometimes when creating repeat patterns, where I have another artboard for creating the assets next to the one where I lay them out.

I've had similar accuracy issues with the Divide operation that have made it unusable for me with both the Windows and Mac versions of Affinity Designer for at least several years now.

I think this is a problem that should be addressed if possible because I do a lot of iconography work that involves a lot of these operations, and I have to work in small sizes in order to preview and export my work correctly.

My workaround was to duplicate objects and perform individual Subtract and Intersect operations on pairs. For some reason, Subtract and Intersect have not given me trouble at small sizes, it's not ideal because it can get quite time consuming and convoluted, but that works.
