What are sketch endpoints and center points that cannot be deleted in the hole sketch? When I do try to delete them Solidworks crashes. How do I get rid of them?

Well I was hoping the screen shot would show me something more obvious but not in this case. I have a couple ideas, go ahead and attach your part file if you can and I'll check it out.
Sorry our customer will not let us share the part. It does seem though this is a reoccurring issue. If I try to delete the dots I get a warning but if I do a box delete around both dots I crash. This is the sketch of m3 taps.
I'm not sure why you would be crashing, system stability is beyond my ability to diagnose. You may be able to work around the error, try these approaches:
If you can't delete these points, see if you can make them work for you. Will it let you merge these points with some of the established points on the same sketch, or delete some of those other points and use the points creating your problem in their place?
Another approach may be to scrap this feature and it's sketch all together and then recreate it with a fresh clean attempt.
Forgive me if you have already tried these ideas and more, I'm reaching a little here, hopefully something here will work for you.
Thanks, I will try tomorrow. I know if i delete the holes the whole thing goes away but I am trying figure out why it happens. I do offset edges to locate my taps. Sometimes I delete or trim them. Just need to find out what not to do. Thanks again.
I haven't been able to figure this out. It seems it could be an arc but not sure how to delete it. This is the error I am getting.

Attach the *.sldprt file here rather than pretty pictures and end all doubt.
Yes agreed. I would like to show the part file but our customers do not allow us..

So, you are saying that the behavior occurs only in this one particular file and you can't reproduce the behavior in a simple part file?
It has happen in other part files. I tend to use lines as reference to put or replace an existing tap. I will try not to do that anymore but without knowing the root cause, hard to know what not to do. I can try to reproduce it in the near future.

I do that all the time (I think), so I am not sure I understand your problem description.

Bryan, it sounds like you're confusing sketch points with sketch segment points.
Sketch points are are individual sketch entites that can be deleted or added independently.
The blue dots that you've circled indicate the endpoints of sketch segments. These are just glyphs to help you identify and locate the endpoints of your consturction goemetry. They are not treated as hole centers by the hole wizard and most of the time you can't delete them. the only time you can delete a sketch endpoint can be deleted if it's between two colinear lines or two coradial arcs-and then it's just a convenient way of merging two entities into one. The blue dot out by itself that you've circled is probably a very short line segment. Since you can't delete and endpoint, you have to window select around the point to select the line and then delete that. You mentioned that one of your lines identifies as an arc segment, it could be that you're trying to create an infinite radius arc by making three points on it collinear-which SW won't let you do.
The errors you're seeing have more to do with your sketch being overdefined or unsolvable. If deleting a segment or relation updates the sketch such that a zero length line or other invalid geometry condition is created, SolidWorks will balk and change the sketch back to it's previous state. Usually in these conditions, you have too many sketch relations involved and you'll have to remove the bad ones. I'd suggest gettng rid of redundant relations (like colinear and parallel).
The SketchXpert tool is really useful for sorting out sketch constraint schemes that have gone wrong. You should look into it.
Finally, if you just don't want the blue dots on the ends of sketch segments, then you can turn them off from the options dialog box:
Hi John, I not sure they are lines or arc segments. The reason of concern is that it crashes when I box them If I turn off the above system defaults the points disappear but if I box the same area they highlight and still crashes. Now If I pick one I can move it by changing the parameters box dim. If I move both of them off the part and box the same area there is nothing there. If I box a bigger area that both include the dots and that same area it crashes but if I just pick the dots it doesn't crash. And no matter what I have done the area above error doesn't go away.
Could you attach your part file or a screen cap of what you are looking at?
