Sketch Entities to small to extrude from

I've traced an image in Creo sketch, with the intention to extrude - remove the profile into the base part. The problem is, I believe, that some of the spline sketch entities are too small and it's causing a regeneration error when I try to extrude - solid. I can extrude - surface, but that isn't what I need here.

 

Larger scaled versions of this same sketch are able to extrude, which is why I'm assuming it has to do with the sketch entity size. I've already set my model properties - accuracy to as low as the system will allow.

 

Does anyone know of a work around or way to modify a sketch to get this to work?

 

Thanks!

Are you positive there are no open ends?

What version of Creo is this? Newer versions will automatically highlight open ends and complete, closed loops.

 

You said you reduced the accuracy, is this absolute or relative?  There is another config option that will let you further reduce the absolute accuracy lower than the default limit.

    By the way, if your model is set to absolute accuracy, the shortest segment can't be less than 2 times the absolute accuracy value.  For example, if absolute accuracy is set to 0.0001 inches, the shortest segment must be at least 0.0002 inches.
