Thin border around overlapping obejcts

Recommended Posts

Hey everyone,

I am pretty new to Affinity Designer and I have one issue I cannot solve on my own or using searches.

To create shadows on let's say an ellipse, I create an ellipse, duplicate it, make this one a bit darker, move it e.g. a few pixels down and to the left and then add the original ellipse as child of the shadow layer. Thus, it looks like a shadow.

Unfortunately, I am facing a problem when some of this layer is overlapping another one. There is always a thin border around the whole ellipse which I cannot get rid of. I attached a file in which you can see it on the right. I used pixel view, because the stroke is very thin in vector view.

I have of course set the border to transparent and in the stroke-tab (I am not quite sure, if it's called like this in the English version) I also set the thickness to 0.

What do I have to do to delete this border?

Thank you for your help!

Why are you making the original a child of the darker one? I do see the same thing as you in Designer but if I put the two ellipses on top of one another (lighter on top, shadow on bottom) and then group them or don't group them there is no border.

That's right, if I try as you suggested, there is no border anymore. But this is not quite what I wanted - if I didn't get you wrong. I want one ellipse and inside of this ellipse a small part which indicates a shadow (left). If I just put it on top of each other, there are two ellipses with too much visible of the lighter one (right):

Oh. Make a copy of the shadow and use that clip/mask the topmost one.

Use an antialising adjustment like firstdefence showed to get rid of those lines.

Thanks @firstdefence, this worked for me. 

Can anyone explain, why this behaviour occurs? It doesn't seem right to me. I know about antialiasing, but I do not understand, why this is an issue here. Or is it just a bug?
