Updated Sketch

[danlamb]

I have updated a sketch but there seems to be a hole in the chain? Is there a analysis tool I can run quickly to find the gap instead of going through the sketch bit by bit?

One way is to start the extrude command, change the curve selection rule to 'feature curves' and select your sketch; a large 'asterisk' type symbol should highlight any gaps in the chain of curves.

You appear to be running NX 10.0 but with the old interface style. Note that the clock is ticking...

But getting back to your issue; yes, there is a way to visually see if the profile has no gaps. Seeing if there are gaps is a bit trickier, but at least there is a way to spot where there MIGHT be problems.

When you're creating your sketch, as you're adding lines and arcs, the end points SHOULD snap together so that they are coincident. If they are there will be no gaps in the profile. However if the end points of the curves are merely one on top of the other but NOT constrained to be coincident then they may or may not be a gap. You can tell that curve end points are coincident or not by the size of the end-point symbol. A large 'dot', the ends are constrained coincident. A small 'dot', they are not constrained coincident. Now even if they are not constrained coincident, there may not be a gap, just that there is no guarantee that there isn't. The picture below shows you what I mean:

Now there is another way that works as well and might actually be a bit easier to use, particularly if the sketch is a bit complex. While in the sketch and with all the curves visible, go to the 'Show/Remove Constraints' function and when the dialog opens, make sure that the 'All In Active Sketch' is selected along with the 'Include' item. Now set the 'Constraint Type' to 'Coincident' and all of the 'Coincident' corners should highlight while the other corners will not.
