An open-source parametric 3D modeller. FreeCAD is maturing more slowly than commercial products but is still very capable. It is useful for 3D printing things designed in other products (e.g. Nomad for iPad).

CAD software and 3D printing are a potential revolution in vessel mold-making for ceramics (3D modelling is another topic). But there are two big problems: There is no way a potter, hobbyist or even small manufacturer can afford the typical software cost. While it is true most have free or low-cost trial or hobby versions, the strings attached are deal breakers. The second problem is the complexity of learning - that can be a bigger obstacle than cost. Until the recent price increase Fusion 360 seemed to be exactly what was needed. A great way to on-board the CAD world, using the free version and its great learning resources and best-in-class user interface. It is new and modern, a YouTube star. It is fully parametric supporting constraints and a timeline. True, it can choke on more complex drawings on consumer computers, but we don’t need to do those. But, for commercial use, it costs $680/yr. But that is cheap compared to some others! Upon discovery of the capability, the cost might be doable for you. Here are the ones you likely cannot afford (and maybe don't want): -OnShape runs in your browser. It focuses on collaboration for teams. Free-version drawings are public but going private costs $1500/yr! -Rhino is usable for CAD but is polygonal and targeted at modelling. It is not fully parametric and does not have a traditional timeline (however Rhino+Grasshopper is life-changing for geeks, both for CAD and modelling). $1000 to buy but upgrading is $500+. -Solidworks is fully parametric with editable history. Its xDesign product (desktop for Windows only, or in browser like OnShape) is $49 (for hobby use) but for commercial use is $2600/yr in 2025. Some upcoming possibilities: -FreeCAD is becoming more viable. It is parametric, has constraints and exports and imports popular formats (but with lots of issues). Its model tree is equivalent to the Fusion 360 timeline, but more clunky and depends on careful setting of constraints. The learning curve right now puts it out of practical reach of most. With a capital injection, like Blender got, this could change. -Shapr 3D costs $299/yr, also works on iPad (which Fusion 360 does not), and uses the Parasolid engine like OnShape and SolidWorks. But it seems to be targeted at being intuitive for conceptual modeling and quick prototyping for drawings that are finalized in other products (limited support for accurate feature placement, constraints, parametrics and boolean operations).

AstoCAD parametric CAD is built on top of FreeCAD The author of AstoCad told us this: "AstoCAD is built upon the robust, open-source foundation of FreeCAD, AstoCAD's core mission is to deliver a more polished, intuitive user experience. By supporting AstoCAD, you not only get an affordable, constantly improving tool, but you also fund the development that makes powerful, accessible CAD a reality for everyone." |

3D Modeling
3D surface modelling tools enable the creation of objects by starting with a basic shape having polygon surfaces and then subdividing, pushing and pulling the quadrilateral or triangle polygon meshes to form shapes. |
