Following my initial model handover, I requested a Skype with the boatyard and the company who will be doing the 3d print. I was looking for clarification on my initial model, as well as the other details that I would need to include with regard to deck fittings, hand rails and the like.
The 3d printer was very happy with my model, as it was one cohesive solid. He explained to me that his process is some sort of sintering (as I understand it). So all cavities and undercuts would have loose powder in them that would have to be cleaned out afterwards. So I have done no more cavities than is necessary from a visual perspective. All the deck fittings are to be printed separately, which makes it easier for me as I don’t have to include every last detail in my initial model.
Along with the scale model, my modeling will also be used for the EMC study. The designers have no cohesive model of everything, as the statutory lights and antennae arrangement only existed on separate ACad drawings. There was an initial 3d model, but of course when comparing that to the actual mast arrangements there were a number of differences. ‘Interestingly’ when I combined the information from the mast lights and antennae drawings, each designer had made use of the same footprints on a number of occasions. This is an instance where I am happy to stick to my lane, and let the boatyard advise..
Now that the initial model is complete, i am finishing off the various visible deck items, producing a single, cohesive solid for each one, that is in the correct location. I have used various methods, depending on the source. From drawing from scratch to importing 3d Dwg’s as a skeleton, to importing meshes.. On each occasion I have been genuinely impressed with Fusions ability and tools that are available for working with data from disparate sources. And I have yet to get over how quick it’s .step file export takes, a feature i use regularly. Exporting to .stl and .obj on the other hand is an exercise in patience, thankfully I don’t do this often.
I am waiting on a few details around the rudder, propulsion and a couple of others. But otherwise my initial approach has proven to be spot on, and has been helped greatly by using a solid modeler that is capable of handling imports from a range of data sources. I have enjoyed this project, and would happily do another one, now that I have wrapped my head around getting paid for a 3d model, as opposed to a drawing pack. And I am looking forward to seeing some pics of the finished product.
