organicspot Posted February 22, 2016 Share Posted February 22, 2016 I was to do something that I assume is straightforward—create a new node precisely at the intersection of the two curves (see screenshot). I can’t figure out how to achieve this, is it possible? Quote Link to comment Share on other sites More sharing options...
crabtrem Posted February 22, 2016 Share Posted February 22, 2016 Forgive me. I am not clear on your intensions. I'm no expert, so please bear with me. Do you want to create a single node so that it breaks the two crossing lines into four separate lines? Or do you want a node just on one line segment? Or do you want a node for each line segment at the same point? Quote Link to comment Share on other sites More sharing options...
organicspot Posted February 22, 2016 Author Share Posted February 22, 2016 My intention is to add one node to the curve that’s selected, and to add it precisely at the intersection. Is that more clear? Quote Link to comment Share on other sites More sharing options...
crabtrem Posted February 22, 2016 Share Posted February 22, 2016 I am only trying to help. I believe I gave some examples of different end results that could be derived from using the term add a node. From your reply, zoom in. Quote Link to comment Share on other sites More sharing options...
organicspot Posted February 22, 2016 Author Share Posted February 22, 2016 … Or do you want a node just on one line segment? … That’s what I’m going for. And I’m not sure zooming in more will make it more clear. Quote Link to comment Share on other sites More sharing options...
crabtrem Posted February 22, 2016 Share Posted February 22, 2016 Zooming in is definitely your best option for the result you want. Quote Link to comment Share on other sites More sharing options...
organicspot Posted February 22, 2016 Author Share Posted February 22, 2016 Of course I’ve zoomed in extremely close, but the result is imprecise. I want the node to be exactly at the intersection. This is a fairly common behavior when creating illustrations. Rivka 1 Quote Link to comment Share on other sites More sharing options...
crabtrem Posted February 22, 2016 Share Posted February 22, 2016 The only thing I can think of, is you probably having snapping turned on. You may also have the companion, move by whole pixels, and force pixel alignment set. Turn those off. I'm not sure why I am evening mentioning them, because that would be the first and most obvious thing to check. But I cannot figure any other options that might cause this. So sorry in advance for stating the obvious and most elementary of things. Quote Link to comment Share on other sites More sharing options...
Staff MEB Posted February 22, 2016 Staff Share Posted February 22, 2016 Hello organicspot, Welcome to Affinity Forums :) Snap to intersections wasn't implemented yet, so there's no way to detect the intersection point precisely. This is coming in a future update.

crabtrem Posted February 22, 2016 Share Posted February 22, 2016 But if he has snapping on, or force pixel alignment, or move by pixel only would be the most likely cause of not being able to align to an exact point even after zooming in, correct?

Staff MEB Posted February 22, 2016 Staff Share Posted February 22, 2016 Yes, snapping can interfere with positioning if the considered point doesn't meet snap conditions. Disabling snapping would allow you to position the point freely without any constraints. The issue here is that Affinity currently doesn't detect (yet!) the intersection point. You can zoom in to adjust the point position until it looks over the intersection but then if you zoom in some more you will see that the point never lays exactly over the intersection. crabtrem 1 Quote A Guide to Learning Affinity Software | Affinity Quick Reference Link to comment Share on other sites More sharing options...

I always tried to allude to that at the beginning, because the cross over is just a visual, accuracy will always be subjective to the scale of your perspective and the tolerance you allow. But for some reason the term accuracy had to be exact. When the term itself is subjective to what end result you are after. Which never seemed to come up?

JimmyJack Posted February 22, 2016 Share Posted February 22, 2016 While we wait for intersection snapping.... As a workaround, you could zoom in super far (100,000%) and add a point to both curves and then snap one point to the other. (Crabtrem touched on this situation above.) One line would change (super) slightly..... at that zoom will it really matter? And, of course, you would have two new nodes, but they would be perfectly coincident. Granted this isn't a great solution if you have to do dozens and dozens. But for a couple here and there..... organicspot and crabtrem 2 Quote Link to comment Share on other sites More sharing options...
R C-R Posted February 22, 2016 Share Posted February 22, 2016 I always tried to allude to that at the beginning, because the cross over is just a visual, accuracy will always be subjective to the scale of your perspective and the tolerance you allow. But for some reason the term accuracy had to be exact. When the term itself is subjective to what end result you are after. Which never seemed to come up? No pun intended but this isn't exactly true. That is because since vector graphics are really just descriptions of geometric paths, unlike pixel bitmaps they are resolution independent. That means at least in theory they can be scaled to any size without loss of positional precision. The "in theory" part comes into it only because computers can't calculate geometry with infinite precision so at extreme scale factors they may not be able to display vector graphics at exactly the right spot, but there is nothing subjective about where they should be placed.

Rivka Posted September 15, 2019 Share Posted September 15, 2019 So it's 2019, any word on snapping to intersections? Quote Link to comment Share on other sites More sharing options...
PixelPest Posted September 15, 2019 Share Posted September 15, 2019 What have you tried so far? Rivka 1 Quote Link to comment Share on other sites More sharing options...
Rivka Posted September 15, 2019 Share Posted September 15, 2019 8 minutes ago, PixelPest said: What have you tried so far? An awful lot and really mix results. Can you show me what your snapping settings are when you did this, because i set up the very same thing and it did not work like that with any setting i could test. In general i feel quite proficient in AD as i did in .ai and freehand before that, but this is one of the small list of things that is making me pull out hair.

Rivka Posted September 15, 2019 Share Posted September 15, 2019 ah its the guides i can't get to snap to intersections! i can get my curser to, and therefor an object to, but the guides only want to snap to pretty random things that don't seem to have much of a pattern.
