Warning: The sketch has not been updated - message

Eric Snyder Dec 3, 2009 10:38 AM

I frequently import DXF files into a sketch of a part. Many times I get a very cryptic message:

Warning: The sketch has not been updated because solving it would result in invalid geometry (such as a zero-length line). Consider:
*Deleting the invalid geometry
*Changing relations or dimensions to eliminate the invalid geometry.

When I look at the sketch sometimes there are entities that are highlighted red and sometimes there is no apparent error whatsoever. If I find something that is red, if I delete it then something somewhere else turns red. This seems to go on until the very last entity is gone. If there is nothing highlighted red then I don't do anything.

How can I get this problem resolved so that there are no errors in the feature tree?

Hi Eric

I have run across this error a few times (but nothing recently)

Are you using the sketch to create a extrude or any other type of feature? I tool I've used is "Check sketch for feature"

If you go to Tools, Sketch Tools, Check sketch for feature (towards the bottom)

You can select a extrude (or whatever) and if there are gaps or duble lines it will highlight the area and you can fix it.

Hope this helps a little.

  Yep. That's a good tool. I discovered it a while back. Unfortunately it never finds the problem with these.

        When you pull in the DXF, are you using the import dialog? In there somewhere is a "tolerance" number for adding coincident relations to line endpoints. Try fiddling with that number.

        Good idea.
        
        I have played further with the Check sketch for feature tool. When I usually use this I don't select any feature to check for. I usually just want to know if the entities are closed. When I checked for Boss Extrude it found the error and I was able to correct it.
        
        I will try the tolerance setting.

        Tolerance setting does not seem to help. The bad entitiy is a spline. Most of the entities are splines but there are no editing handles for any of them. I can't see what the editing handles look like for the small (0.011" long) spline.
