For more accuracy, technical specificities and better visualization of the project, parametric modeling software is a better solution. Direct modeling allows to manipulate your design more quickly, so it can be convenient at the beginning of the conception of a project. Indeed, direct modeling is used frequently to make geometries, you can’t work on the relationships between features, you can only modify the selected surface of your model. Direct modeling doesn’t create model features such as parametric solutions. Parametric and direct modeling are two different modeling techniques. These CAD programs might be perfect for your rapid prototyping process. It is also used for architecture projects, aircraft design, or even machinery. It is great to have parametric software if you have an automotive project for example. This tool can be useful for many different industries, but parametric modeling is especially used in mechanical engineering. If you need some help, we have a blog post that will help you to deal with design guidelines while working with a parametric modeling software. Indeed, it can reduce your production time as it can easily be integrated inside of your manufacturing process.īe careful, you will have to be a little bit experienced if you want to use a parametric software. Parametric modeling software is a really good tool for manufacturing. These 3D programs are really great to see how the model directly changes when something is modified, and you can easily reuse the data of a 3D model to create a new design. Why you should use a parametric modeling software Parametric modeling is actually focusing on relationships between features, and between parts, assemblies and drawings. These are attributes that include length, width, depth, orientation, geometry, material, density functions, etc. It will totally be adapted to your design intent.Īll the models created with this process have what we call features. Indeed, it is good to create designs that need to be modified on a regular basis. It is a practical process if you need to produce products with little variations.

This modeling process is built from mathematical equations. This modeling process is great for projects with a lot of manufacturing requirement and that need a high accuracy such as mechanical projects. It is used to define a dimension’s ability to change the shape of model’s geometry immediately when the dimension value is modified. Parametric modeling can also be called parametric solid modeling.
