No, not the fine shapes of the object, rather the details that make real object behave to real physical laws. You take the same shapes and combine them to make an object that we use our machines to “print” real. Modelling real objects is very similar to this except your output is now 3 dimensional. We use all manner of objects from 2 dimensional and 3 dimensional to craft a likeness and then we render that object in all it’s pixelated glory for all the world to see. It involves imagination and creativity to put together shapes into virtual real-world objects. Virtual modelling is an art form in and of itself. For those not lost, don’t despair, there’s stuff in here for you, too! I’m going to make this as painless as possible. Have I lost you yet? If so, then I may be able to help. Virtual objects don’t object to intersections of mass, or multiple faces on the same plane occupying the same coordinates. A goodly number of us fall into this category, I’m sure.īut creating virtual objects is not the same as creating objects in the real world. A hobbyist who tried to keep his skills updated so that he could create virtual objects of things that interested him. Now, I’ve had a background in 3D modelling for about the last 8-10 years. That’s why I felt the need to write this. What about the rest of us? We model and wonder why we get errors when slicing the file. These designers have it easy as they have the experience to “create” what they want. Ones with a background in crafting real-world objects and milling them out of solid real objects. For some it’s simply a matter of using a CAD program and letting it all hang out. We’ve all come across a dilemma that plagues our being getting our ideas out of our head and onto the machine. I say “infernal” and should use “miraculous” instead, but I won’t. That’s why we got this infernal contraption to begin with. I only hope that I’m not getting stuff wrong, but from the way that I’ve been outputting my own models, I think I’ve got most of it right. The modelling section should be completed in another week or so, the Fix section, another week after that. It’s a work in progress, folks as I have 3 kids, a wife and a job, plus the “infernal machine” to placate, so bear with me. A lot of people aren’t conversant with 3d software, or get bogged down with the terminology when coming across the forum, so here’s my take on it. I’ve been wanting to write a primer on how to get a model ready for slicing when you create it. I’ve been seeing a lot of posts on modelling and how a model isn’t really slicing the way that they want it.
