What you need to know about parametric modeling?

What you need to know about parametric modeling. Parametric modeling allows creating a project in which all model parameters will be taken into account. And they will be interrelated, and changing one of them will cause the others to change (for example, the details in the assembly will be moved mutually). Due to this, it is possible to eliminate the risk of fundamental errors by testing various design schemes.

Even at the dawn of the advent of CAD, the idea of ​​using this type of modeling arose, but it could not be realized because of the small power of computers of that time. The situation changed only in 1989, in which the first programs for parameterization appeared.

Parametric modeling can be either two-dimensional or three-dimensional. The first is a parameterization of the drawings and is rarely used. 3D custom 3D modeling has great efficiency. In currently used CAD it is the main possibility.


Types of parameterization

There are 4 types of parameterization; some of them are suitable for creating 3D visualization of interiors.

Tabular: It is a process of forming a table, which contains the parameters of each part. To have a new instance, the size is selected from it. Opportunities when using this type are opened small, because In most cases, you can not set arbitrary values. However, it is often used to quickly and easily form part libraries that are used to create a design project.

Hierarchical: It is characterized by displaying the whole process of creating a model in the form of a tree. The program remembers each user action and the hierarchy between the elements. The tree is formed in a separate window. This type of simulation is most often used in combination with one of the following.

Variation parameterization: it is also a dimensional one . The basis is the construction of sketches. The developer of the model imposes restrictions, which determine the relationship between the parameters. This is done using a system of equations. The advantage of this type is the possibility of easy modification of the 3D model.

Geometrical: Its distinctive feature is the recalculation of the geometry of each parameter based on the change in the parent parameter. The model consists of lines that form the basis of the model, as well as design elements and image lines used to trace the basic ones.

The advantage of this type is the ability to flexibly edit an already created model. If you need to change something, simply create a new design line, avoid losing the relationships between the elements, and attach to it the previously drawn image line. You can order a detailed visualization or simply get a cost estimate right on the day of treatment.
