Problems with new axonometric grid?
Hi Johan and everyone,
first of all thanks a lot for your work on the grids!! Today I wanted to give the new functionality a try and was a bit stuck, however. Maybe this should go to the bug tracker directly but what I experienced seemed so weird that I thought I'd ask for other people's experience first, since I reckon that Johan would have realized if he had encountered this behaviour, too. Maybe I got something completely wrong, although I don't see what this should be.
The rectangular grid works like a charm. But when I create an axonometric grid instead, I cannot get the pen tool, say, to snap to any of the intersections of the grid lines. Instead, it snaps to seemingly random points in between. Also, with "always snap" enabled, the mouse pointer doesn't cleanly jump from one intersection point to the next but shows a kind of "juddering" behaviour, as if it was snapping to some invisible (smaller) grid that's not precisely aligned with the visible one. When "always snap" is unchecked and very small sensitivities are chosen, it seems to work better, but the precise snapping points are still missed to a certain extent.
Furthermore, when assigning a different color to the major grid lines, they are not drawn as continuous lines but only segment-wise and at irregular distances. To me it looks as if the regular grid lines were repainted with the new color, but since both lines are located at the same positions, sometimes one color dominates and sometimes the other. (This may also explain why the segments seem to change when zooming out.)
Has anyone else seen this or is it just me? Does this work correctly for you, Johan? I was experimenting with the latest svn version (revision #14815), but this seems to occur with older (yet recent) versions, too. Please tell me if you want me to add this to the bug tracker.
Thanks for your help! Cheers, Max
P.S.: Wouldn't it make sense to have different colors for regular and major grid lines by default? And IMHO the default spacing for the axonometric grid should be larger than 1.

I think it's because there's an iso grid but there's no snapper for that grid yet. It needs to be written :) So for now it uses the rectangular grid's snapper.

Yes, I've seen this too. Something's wrong with major lines in iso grid. This is worth submitting a bug report.

Don't think so, imho a different opacity is enough

Why?

I'd disagree. I'm thinking of things like graph paper where the major lines are red and the minor lines are blue. I don't think that should be the default, but I do think it should be possible.

It _is_ possible, just not the default :)

Agree with Bulia.
Good grid paper is the same size, and the grid should be visible as little as possible. Having grid lines of different colors is not very good, it might pass as data when there's not, and it add nothing. Thickness or opacity difference is perfect.

Correct.

I know about this problem. I decided to make grid infrastructure first, then continue with the axonom grid; but now I am busy with Summer of Code: Live path effects. Maybe I should just disable it for now, but I was hoping it inspires others to fix it and/or implement new grids.
Cheers, Johan

Ah. I hadn't ever considered the possibility of having a rectangular snapper for an iso grid, whence my confusion. Thanks for clarifying. But I think it's very confusing for users who don't expect it. So if there is no one in sight to implement a snapper for that grid soon, I think it should rather be temporarily disabled. (And it should probably be mentioned somewhere that snapping to iso grids doesn't currently work.)

Okay, for the record I'll add that later, even if Johan said he knows about the problem.

Good point. I must admit that I hadn't even realized the different opacity - probably both because the two kinds of gridlines only become visible at a larger zoom and because the distinction is not very noticeable at the moment. So maybe it would be nice to increase the contrast a bit. But that's personal taste, and as Bulia pointed out, it can be changed by the user.
And IMHO the default spacing for the axonometric grid should be larger than 1.
Why?
Hmm, it was just a personal feeling. Currently when I create an iso grid at the default zoom level, the gridlines are much more closely spaced than with a default rectangular grid. I like the latter way better becuase the page looks less cluttered, but I don't use grids very often so users more familiar with them may have different tastes. Just thought I'd mention it.
