![]() They announced it back in early September, but it has only been available for purchase since the 14th of this month. Just wanted to add if you haven’t heard already, that Pixologic just came out with ZbrushCore a little more than a week ago. This post originally appeared in Shapeways Magazine on Oct. If a design wants to do both, try mixing and matching software within your process. If a design needs to emulate a real-world or imaginary object or showcase your artistic vision, modeling could be a solution. If a design needs to be functional, fit to other real-world objects, or have specific measurements, starting with CAD is the way to go. Overall, knowing what you want to achieve with your design is vital to choosing the right tool for you.

This always for different ways to manipulate the shapes, often in ways that look more organic. The advantage of modeling over CAD is that modeling software gives users direct input into each vertex or surface individually or as groups. These points and surfaces come together to form the edges of a 3D object. In many cases, programs will let you switch between these systems with ease, depending on your workflow. This may be based around a system called NURBS, or may be simple polygons composed of vertices, edges, and faces. Modeling softwares are based around surfaces created from 3D geometry. Long used by the film and video game industry to make animation and special effects, you can also use these programs to create printable 3D models. This is where 3D modeling software comes in. That said they may not give direct enough control over a design to allow for freeform, artistic work. Any functional object around you (your phone or computer that you’re reading this blog on) was designed in CAD software.Įxamples of CAD: Solidworks: Industry standard CAD softwareįusion 360: Free for students, startups, and makers!ĬAD software is great for functional objects, things that need to work mechanically or fit to a real world device. Simple shapes can then be added or subtracted to create more complex forms.īecause CAD software takes its roots in 2D drafting it is mainly for functional, measured 3D objects. Nowadays we have tools like 3D printing so that the design can be interpreted by other software (CAM or Computer-Aided Manufacturing) to create the tool path or slicing for 3D printing.ĬAD programs take these 2D drawings and digitally translate them into 3D rendered “objects.” In some cases these are just “shells” or surfaces, while other programs treat the object as mathematically solid material. This could be done manually or with a successive process of machining. ![]() Drafting software comes from a long lineage of product designers, architects and engineers who would draw 2D plans, complete with measurements, which would be handed over to technicians or craftspeople who would interpret the designs and make the said object. READY TO PRINT? START HERE CAD (Computer Aided Design/Drafting)ĬAD programs ask the user to “draw” a 2D shape and then turn those drawings into 3D forms, as either solids or surfaces. Alternatively, 3D modeling packages more commonly used for making organic elements used for film special effects and video games.ĭepending on the goals of your design, you may use both types of software at different stages of the design process to make the final 3D-printable design.īelow, we’ll go over how they are different and provide a few examples of each software type. CAD software is used when creating industrial, mechanical objects. Overall, design software falls into two camps: CAD and 3D Modeling. Knowing what you are trying to make will dictate the type of software you will use. The answer to that is a little complex, but it hinges on one simple idea: What are you trying to make? There are lots of great software packages for 3D design out there, each tailored to a different type of product design. One of the most common questions we get from those who are new to digital manufacturing is “If I want to design something, which software should I learn?”
