The answer is frustrating because it does NOT mention the origin or anything like that... Rather it implies that the fault is with the design alone. How does one make two models share an origin? Is there a setting during the export where I can make the STL use the same origin system as the SLDPRT? Obviously they have the same SLDPRT origin since they are aligned when constrained by mating the origin planes.

To anyone else having this issue, I did not realize that after models were grouped, they could still be moved relative to each other within Cura by clicking and dragging on one of the grouped models while holding CTRL. I was able to make this print work by zooming in and manually aligning by eye. The "if designed correctly they will align automatically"-answer is frustrating. The two models in question began in solidworks as one model with two bodies. I deleted one body, saved as STL1. Went back to the 2 body model. Deleted the other body and saved as STL2. They had the exact same file format and origin definition, but they were automatically offset in all 3 dimensions when grouped in Cura. Please advise if this method is bad form... PS: No scaling before, after, or during. Default export settings.

I have been using Ultimaker 2+ Extended for some time with no issues. This is my first week using the Ultimaker 3, and I am not able to get Cura to merge the models correctly. The models that I am using have identical coordinate systems (I have them mated together in a solidworks assembly by the origin planes [top-top, front-front, right-right]), but when Cura merges them, there is an offset along each axis. Is Cura treating the center-of-gravity as the origin or something ridiculous like that? What happened to the feature that allowed me to place models overlapping each other and manually move them around?
