KOP won't constrain in inventor

If the part is molded it probably has a small amount of "draft" to assist in removal from the mold. Draft is a small taper angle so the part is thicker towards the leading end when you remove the part from the mold. Draft can be hard to detect visually on a CAD tube. You have to measure the part to find it, especiaslly if you are using a perspective rather than a parallel view. If you are having draft issues either constrain to holes or use edges rather than surfaces.

I happen to be having the same problem and have tried to constrain to edges and holes but nothing has worked for me. Any other help would be much appreciated.
