Pathfinder Anchors way off!

[K1P57A]

Hello everyone,

I've recently encountered an issue that I have not had prior to the latest 2017 update of Illustrator.

I need to create shapes that, at a later stage, will be cut out with a cutting plotter.

When I join shapes with the pathfinder tool the anchors now "jump" to weird locations, which, needless to say, makes this function useless for me...

Shape not joined yet, correct alignment

After Pathfinder has joined them...

I've Googled for quite a while now and haven't come up with any solutions yet. I'm desperate, please help...

Best regards,

Philippe

how are you creating those tangential shapes/lines? could that have something to do with it?

what document profile are you using? is snapping to pixels on?

do those shapes have strokes?

[Doug A Roberts]

something i always forget about: what's the accuracy of pathfinder set to (in the palette's menu)? how large are these objects?

Hey dougofakkad,

The shapes you saw I created using the ellipse shape tool for the circles and the pen tool for the shapes connecting the two circles.

Document profile is print. None of the snapping options are turned on.

I set the accuracy to 0.001pt now (which is the lowest possible) and this indeed is way more accurate, however it still creates an offset (just not visible any more) but when I drag the anchor out it's clearly still two points (see image).

After adding shapes with pathfinder

When I drag the anchor out it's still 2 points, just sitting much closer on top of each other...

Any ideas? In the older version it used to be an option that new shapes shouldn't be aligned to pixels but I somewhat can't find this option in the new version...

[Doug A Roberts]

yeah they changed the align to pixel grid thing; you can now see the options via here (top right in the control bar):

getting inconsistent results myself. sometimes i end up with two points, sometimes one.

K,

Maybe a silly suggestion, but what happens if you use the Common Tangents script in the free set available here?

Have you tried the Pathfinder options? There's a setting to delete points that are not needed. Also you can adjust how exact the result should be.

what happens if you use the shapebuilder tool to unite the circles instead ?

I found Pathfinders default "Precision" setting is not precise as it can be... the default setting is set to 0.028 pt.

Go to Pathfinders pull down menu and select "Pathfinder Options...". Change the default settings to zero (it will set to .001 as the minimum). Here is the settings I use:

These settings stay until you quit Illustrator. You will have to reset them every time you launch Illustrator.

Anyone know a way to change these default settings and make them stick?

[Ton Frederiks]

No, I really would like to have this made into a default setting, but it is not sticky.

Feature request (as more people ask for this, the more likely it wil change on a happy day).

You absolute legend. I've been ripping my hair and keyboard keys out trying to sort this. The align to pixel grid, snap to options were all explored and still getting strange and messy pathfinder results...this has done the trick!! Thanks a million!
