There isn't any especially easy way - for this one I went through and dragged each point to check. If you can drag a point away and then you see another one underneath it, then that's a stacked up point.

But a lot of times a stacked-up point will not have quite such a dramatic effect - sometimes it won't cause a problem until you try to do some kind of boolean or intersection operation in that area.

I wish I could just automatically process the curve to get rid of stacked-up points, but taking away a stacked-up point does change the shape of the curve in that area, so I'm kind of hesitant to do something automatically that changes the shape... Although I suppose I could just move it by a small amount like 0.01 units or something, that would have a pretty minimal change.

I guess that the way the points get stacked up is when you have 2 curves near each other and you drag the second-inside point and then it gets snapped on to the end of the other adjacent curve, I suppose it is also possible to detect this and not do the snap in this case, that could also help.

How about for a curve, when you select "Show points" if it detects stacked up points, display their handles in red? If you show the stacked points, thats good enough.
And if it's too expensive to run all the time, a "Check for stacked points" command would be useful to have.

HI Crusoe,

re: Stacked points in red.

This is a great idea! I don't think it should be hard to do, I will see if I can give it a try tomorrow.

In the next beta, when you have points stacked up, a red frame will appear around them. This sticks out pretty well so hopefully it will draw your attention to that point to unstack it. Here is what it looks like:



Thanks Crusoe for the great idea!

Hi Michael,

That solution looks good to me :)
Much better idea than having to move each individual point to find the culprit.

regards Colin
