It makes sense to use Direct modeling when you are conceptually exploring different ideas for a model and you don’t want to deal with established shapes and dimensions as you are constantly manipulating the design. You just design until you get the shape you want.

Parametric vs Direct Modellingĭirect modeling lets you quickly create and edit geometries without you needing to worry about defining the features and constraints of the model. You may be asking yourself if the Parametric or Direct Modelling paradigm is better suited for your specific needs, so I’ll quickly go through the main aspects and differences of each one. Such is the case for example in mechanical engineering-related projects. In contrast to Direct Modeling CAD software, Parametric ones are better suited for cases in which precision is of the essence. So you can modify the entire shape of the model at once, not just individual parts one at a time.įreeCAD corresponds to this category of CAD software. It allows you to automate repetitive changes as it eliminates the need to constantly redraw a design every time the dimension values are modified. Parametric modeling is a computer-aided design (CAD) paradigm that focuses on establishing the shapes, constraints, and dimensions of the model being designed. Being that it is free open-source software you will easily find a lot of tutorials to learn from and get you started with your own projects.Īlthough it is not as easy to learn as Tinkercad, it definitely is more versatile. It is known to be a good entry point for designers new to the modeling world. This free open-source parametric 3D modeling software can be easy to learn if you have the basic knowledge of the tools. Let’s get started! Is FreeCAD easy to learn? In this article, I’ll try to dig deeper into the main features, advantages, and disadvantages of FreeCAD, in order to help you decide if it is a good fit for you. Having said that, the choice of which CAD software to use is a personal one and depends greatly on the specific needs of each individual. One of its greatest advantages is the fact that it is completely free and that it has a large community of users.

Having said that, is FreeCAD good for 3d printing?įreeCAD is definitely one of the most popular parametric CAD programs available, and it is both suited for hobbyists and professional users. There is an extensive list of CAD apps that make it difficult to decide which one is better suited for your needs.

Sooner or later, there comes a time when you will have to design an entire object by yourself, or at least modify an existing one in order to meet a specific requirement of yours. When you first get your hands on a brand new 3d printer, you can spend hours printing objects available on Thingiverse and MyMiniFactory.
