Print a portion of a model

Hi

Yes, I am new to 3d.  It is awesome, when it works.  I would like to know if I can take a portion of a model and print it separately.  I downloaded the Red Rocket gas station.  There are no sections.  It printed the whole thing at once, well not at once, it took over 18 hours.  Would there be a way to take the rocket on the roof, for example and print it without the rest of the model?  I think this would save me time and use less supports.  When I printed it, it was more support then gas station.  And in removing them, I broke the model quite a bit.  If this can be done, please let me know.  I am using Cura and an Anet ET 4.  Thank you in advance.

Yes, the models can be edited.  If you have the CAD model then that would be the best.  An STL can be edited in software like MS 3D Builder.

Without actually seeing the model I can't tell much.  Sometimes you can sink a model into the build plate in Cura leaving just the part you want to print.  Then bring it back up and put a support blocker over the top part and just print the bottom.  If you put a couple of matching 2.2mm holes in each part you can glue in pieces of filament to use as locating pins to align the parts when you assemble them.
