Hi! Inventor part has a fixed valid model range of +-100 meters in X, Y, and Z direction. I believe the project location is far away from the origin exceeding the model range, right? If yes, this is not a supported operation. You need to keep the geometry within the valid model range within a part. In an assembly, such restriction does not apply generally.
Many thanks!
