Thanks Diederik!

Ok, so it seems that snapping to group centers can only work when snapping to nodes is disabled (and the only option enabled is snap to center).

Since 0.91, it seems that snapping to nodes is required for many more situations, so I've been keeping them generally always "on". And the idea that certain options only "work" when other options are disabled, did not occur to me.

Even with the options set up properly, it looks like the group centers can only snap to guides or grids. Is that correct? They can't be snapped to nodes, since nodes are disabled. And I can't seem to snap to the center of other groups either.

At the time when this problem came up, I was trying to snap a group of circles which are arranged in a circle, to another group of objects which are arranged in a circle -- so that they all share the same center.

I guess that (snapping group center to group center) can only be accomplished using a grid or guide to accept the snap?

Thanks again, brynn

Sorry Brynn, I missed your earlier message for some reason :-(

Yes, this is possible. I'll send you a screen capture with a demo privately, it's too big to attach here.

I don't think this is un-answerable. But maybe the reason the center of a group can't snap is similar to the reason why it's not possible to snap/snap to, center/rotation center of an object which has no fill?

Thanks again :-)

Hi Friends, Are we supposed to be able to snap, or snap to, the center or rotation center of groups? I can't seem to make it happen. I can snap to the centers of individual objects in the group, but not the center of the group. I tend to think of a group as a type of object. But maybe not?

Thanks for any clarification :-) brynn

brynn previously: Ok, so it seems that snapping to group centers can only work when snapping to nodes is disabled (and the only option enabled is snap to center).

Diederik previously: Not for me though. Whether snapping to nodes is disabled or not doesn't matter at my machine.

brynn current reply: No, for me, snapping group centers can only happen when snapping to nodes is off. I've also just tested in Inkscape 0.91 64 bit (7z version). For the 32 bit version, I used exe installer. Windows 7, 64-bit.

brynn previously: Since 0.91, it seems that snapping to nodes is required for many more situations, so I've been keeping them generally always "on".

Diederik previously: Can you provide a bit more detail?

brynn current reply: Yes. We've been getting questions in forums about this, since 0.91 came out. For example, in 0.48.x, a node on a path would snap to another path, with having only Snap to path enabled. Now, Snap to nodes must be enabled too. And it's a good idea to have snapping to both cusp and smooth, because in 0.91, Inkscape can't always tell the difference which type of node is which. I think I made a bug report about that.....can't remember for sure.

brynn previously: And the idea that certain options only "work" when other options are disabled, did not occur to me.

Diederik previously: That shouldn't happen. If you can show me what breaks for you, then I'll try to fix it

brynn current reply: As I said, the center of groups can only snap (to anything) if snapping to nodes is disabled.

brynn previously: Even with the options set up properly, it looks like the group centers can only snap to guides or grids. Is that correct?

Diederik previously: No, that's not correct. They can snap to paths, bounding boxes, nodes, etc. Can you show me your settings? A screendump will do, and you can send it off-list.

brynn current reply: I could send you a screenshot, but I'm not sure if it's needed. With further testing, I was wrong about that.

I can snap a group center to: path, path intersection, bounding box corner, bb side, bb side midpt., guides and grids

I cannot snap a group center to nodes, bounding box center or line midpoint.

And as I said before, group centers won't snap to anything, unless snapping to nodes is disabled.

Details: When I try to snap to bbcenter, just nothing happens. When I grab the group with the mouse, the group center becomes a red dot. But it never recognizes the bb center.

When I try to snap to line midpt, when I grab the group, the red dot does not replace the group center. It replaces the line midpt closest to where I grabbed with mouse. So the group center can't snap because there's no red dot there.

If you need anymore details, let me know. I can send screenshots if you need. Although I don't have a very good program, and it can't catch the mouse or tooltips. But Prnt Scrn catches the red dot.

That's all for snapping group centers to something. I'll test snapping something else to group centers after I send this.

Thank you very much, brynn

Not for me though. Whether snapping to nodes is disabled or not doesn't matter at my machine. I can snap a rotation center to a grid or guide regardless. Tested on both rev. 14044 from April 2015, as well as a very recent revision.

Since 0.91, it seems that snapping to nodes is required for many more situations, so I've been keeping them generally always "on".

Is it a recent download? Because that you're in fact using 0.91.1 I believe, which has this fix included: https://bugs.launchpad.net/inkscape/+bug/1422296

JFYI: Inkscape 0.91.1 has _not_ yet been released - current available latest stable version is still 0.91.

Regards, V

Ok yes, I will try the dev version. Except at this moment, I get Bad Gateway error on the website. Will download when I can and will report results.

Thanks, brynn

Yes, you're right. Thanks for chiming in. I was confused by this link on the downloads page:

https://inkscape.org/en/gallery/item/3938/Inkscape-0.91-1-win64.7z

Which to me suggested that this was v0.91.1. I just downloaded that file, and this is indeed v0.91.0

Brynn, please test a development build and see if any snapping problems are still remaining. I will happily fix them!

Results:

When snapping to smooth and cusp nodes are enabled, the center of groups won't snap to anything.

True indeed for the center, but not for the rotation point. See this bug report which I just filed:

https://bugs.launchpad.net/inkscape/+bug/1540137

Please note that the smooth and cusp node options have nothing to do with this. They are in a different snap group of the toolbar. The center and rotation center are not nodes.

The smooth vs cusp node confusion still is happening. (Actually, since I've been functioning with that distinction for snapping, I'm starting to wonder if it matters which node type is snapped. When do we need to snap to one type and not another?)

A path can have many smooth nodes, of which you cannot typically tell where they are. Snapping these is typically not desired, and difficult to control. Also, if there are too many then Inkscape might have a hard time in calculation the optimal snap. Cusp nodes however are easy to locate, because they are at discontinuities in the path. It's the cusp nodes that you typically want to snap to something. Hence the distinction between cusp and smooth nodes

I'm not sure about snapping the center of a group to a bounding box center. A snap does happen....yes, A snap happens. But the indicator says rotation center to rotation center, rather than rotation center to bounding box center.

That's likely because they're on top of each other? Inkscape can snap to either the rotation center to bounding box center, both being in the same location? If so, please drag the rotation center to a different position and try again

Thanks Brynn!

Ok, regarding the questions in forums, that is all covered in the bug you mentioned https://bugs.launchpad.net/inkscape/+bug/1422296.

Regarding Inkscape being confused between cusp and smooth nodes, here's the report I made: https://bugs.launchpad.net/inkscape/+bug/1422296 This happens repeatedly for me, and for that reason, since 0.91, I keep snapping to both kind of nodes almost always "on".

All of these issues are regarding 0.91, 32 bit from exe installer and 64 bit from 7z.

Exact steps to reproduce the problems with group center snapping.

Setup snap control bar: Enable snapping Snap nodes, paths, handles Snap cusp nodes Snap smooth nodes Snap other points Snap center of object Snap rotation center

Drag a group center near any snap target, making sure the snap target is set up on the control bar. Will not snap.

Next, disable Snap to cusp nodes and Snap to smooth nodes.

Drag a group center near snap target. Snap happens.

Except in these 3 cases:

1 - Snap group center to center of anything - never happens. 2 - Snap group center to nodes - can't happen because enabling snapping to nodes prevents snapping center of group to anything. 3 - Snap group center to midpoint of segments -- I will send a screenshot off-list, in case it's too big. The screenshot will show the red dot isn't on the group center, when trying to snap to midpoint of line segment.

Settings in Inks Prefs: Enable Snap Indicator - enabled 150 delay Only snap node closest to pointer - enabled Weight factor 0.8 Snap the mouse pointer....constrained knot - disabled

Settings in Doc Prop: Snap to Objects - Snap only when closer than 20 Snap to Grids - Always snap Snap to Guides - Only when closer than 20 Misc - both disabled

Screenshot coming separately.

Thanks again, brynn

brynn current reply: As I said, the center of groups can only snap (to anything) if snapping to nodes is disabled.

I cannot reproduce that, but if that is the case than this is very bad! Can you provide me the exact steps to reproduce this behavior, a screenshot, and a sample file in which this happens? Also, is this with 0.91 or with 0.91.1. Can you reproduce this behaviour too with a recent development version?

brynn current reply: I could send you a screenshot, but I'm not sure if it's needed. With further testing, I was wrong about that.

Works for me! See attachment. I guess that either your snap settings are different, or you are using 0.91.0?

When I try to snap to line midpt, when I grab the group, the red dot does not replace the group center. It replaces the line midpt closest to where I grabbed with mouse. So the group center can't snap because there's no red dot there.

If you need anymore details, let me know. I can send screenshots if you need. Although I don't have a very good program, and it can't catch the mouse or tooltips. But Prnt Scrn catches the red dot.

A print screen will do just fine.

BTW, what are your settings on the snap tab in the document properties dialog? And what are the settings for snapping in the preferences dialog?
