It depends. If you have the physical model then yes, or if you can make a model then yes. Smedit is great for that. The downside is once you make the blueprint, you can't alter it. The core will be placed in the exact center of the ship, so change that if need be. Importing it to starmade will then give you a blueprint with lots of ugly extra blocks. I smooth out the entire hull with another color before removing the excess.
