post the file, or click (show constraints) and just delete all and start again.

There are certain cases where a red cross is of little concern.

Perhaps you are neglecting to add a "fix" constraint to one of your points.

I don't think I've ever used a fixed constraint since leaving MDT?

Interesting, I've just used several today and don't remember ever using any
in MDT.

Re: Sketch problem, please help.

MDT automatically places a fixed constraint in the first sketch of every part as soon as you "profile" it. (Remember having to profile every sketch?) So I'm sure you did even if you weren't aware of how MDT was working. Often in the wrong place for the design intent, so you have to go back and delete it and then replace or add two location dimensions.

It sounds like you may not be using the center point as a base for your sketches. This was not so important in MDT but in IV its crucial. Just remeber, project the center point in your sketches.
