3D design and modeling

Share this post

Definition

3D CAD (Computer Aided Design) design and modeling refers to the digital creation of 2D drawings and 3D models.

To date, this operation has replaced manual design in all sectors of the manufacturing industry.

The term CAD has been around since 1959, when Doug Ross coined the term “computer-aided design” following the development of a program that allowed his team to design electronic circuits on a computer.

The automotive, aeronautical and electronics industries have been adopting this practice in the 1980s.

In subsequent years, solid modeling systems have been enhanced with contour representation, a more coherent way to describe virtual objects via edges and interconnections.

SolidWorks, SolidEdge, and Autodesk Inventor systems adopted this method.

In the years that followed, all sectors of the manufacturing industry adopted the principles of 3D CAD modeling followed by the increasingly widespread motto: if you want to print it, you have to model it!!

All 3D printing processes currently in use necessarily require a 3D model of the object to be made.

Utility

3D CAD modeling allows you to create mathematical models essential for the production of an object.

The designer often enjoys putting his first ideas on paper.

In a second step it is necessary to transfer the ideas to modeling software that allows:

  • the creation of photorealistic renderings for product presentation to the end customer;
  • the definition of the bill of materials essential for assembly and cost estimation;
  • the design definition of the molding production equipment;

  • simulations of different nature;
  • the definition of three-dimensional models for 3D printing.

Process and technologies

3D design is a rather complex operation: advanced software and a high level of information and training are required.

We can distinguish three different modeling methods:

  • ORGANIC 3D MODELING FOR MESH

    • Widely used for the film industry, character modeling, animals.
  • GEOMETRIC 3D MODELING

    • It is the most widespread technique in product design. We mainly use Rhinoceros, particularly suitable for industrial design projects studied down to the smallest detail.
  • PARAMETRIC 3D MODELING

    • This type of modeling allows you to obtain a continuously modifiable model with obvious savings in terms of time. This type of modeling is generally adopted in mechanical-engineering fields.

Case histories

Our experience in 3D CAD modeling has now exceeded 20 years.

Having design skills is a significant added value because it allows us to always have a critical attitude on the project.

This expertise allows us to better follow projects where the customer gives us the final 3D files.

Our design support is complete and always included in the production of both prototypes and series.

This approach is the result of years of continuous training in the development of new industrial products, prototyping and production processes.


Our ENGINEERING services are:

  • Feasibility study and 3D CAD mechanical design of consumer products, mechanical components, special machines and test benches.

  • Drawings development , assembly assemblies, drafting of bills of materials and technical manuals.
