It will stop selecting at the break!
I have been struggling through this for a while and decided tonight it's time to ask.
But when I shift click on an entity, I always hope that it will select and give me a nice red selection of the shape I'm wanting selected.
HOWEVER, sometimes I don't get that and only part of the geometry will be selected. When this happens to my understanding this means there is a break. Question... how do I find the break? There are many times that it's invisible and no matter what I do I can't seem to find it. I have tried trim one, trim two, all the reorganize commands, etc etc.
There's gotta be a good way to pinpoint the problem in the geometry. Any pointers?

Thanks. There are cases though where it will select differently depending on where you click.
i.e. it may only highlight 1/4 of the bottom a circle if you click at one point, and 1/2 if you click at a different point and it doesn't always correspond to equal a break point. If it were selecting 1/4 of a circle you'd think if you go Select None then click on the other 3/4 that didn't select it'd select the other 3/4. This isn't always the case. This is what's throwing me off.
Also, I usually use Trim one or two to try to fix the break but that doesn't always work. Is that the right tool to use? In an arc I use Fillet and guess at what needs to fill the break.
Remember that the selecting is "Chain selecting"... So where and how you clcik will be determining which way the selection is traveling.. You would evaluate by shift clciking either end of the same piece. Filling a gap would be determined by the gap, for me.. Trim may not always be the right choice.
If you have "true arcs" you can just delete all but one, then select and right click the one and choose "entity modify" and just reset the start and endpoints.
I think the main thing would be to understand how you ended up with a gap in the first place. This will be your key.
Here's something interesting, I selected by shift clicking the bottom left of the shape and look what happens. It won't select the entire shape as I would like it to but I get a selection that covers a good amount (Can't seem to find the breaks) but then two pieces that aren't continuous to anything selected also get highlighted in the click.
How does this happen?
Here's the actual file.
What version are you using?
Your issue is that there are doubles overlapping. So when I shift clcik, it selects the entire line, but "looks" unselected in areas as they are covered by double "non selected" geometry.. You can see this by doing that shift clcik (Where you see non connected geometry select) using the blank tool.
You can fix this by showing all your geometry and running utilities-reorganize-erase doubles on the whole set. Then you can shift clcik the ends of those chains to make a contour.
You may want to remake this file though. When I open it in V24 there are some wierd phantom remnants of some contours that I couldnt get rid of (They didnt show up in V23 1812.) I can get rid of them by saving the file as an iges and reloading it in. But I would have to re-create the layers after that.. I would suggest a bit of time doing this. Reload the iges. Erase doubles, then reset your layers and features.
You have multiple entities on top of each other.
Go to Utilities > Reorganize > Erase Doubles and select All.
There was also a line segment missing in upper left form. But that may have been blanked when you created the contours for your Circle feature. (at least that line didn't look like it belonged with the Circle paths)
You should be able to correctly chain select the contours after above fixes.
Burr...it appears the features had the phantom contours selected. Clicking on the Geometry tag of the feature made them disappear for me.
Ahh, good catch mold! I didnt think of that...
