Most Common 3D CAD Design Services


Today, the magnificent advancement of software and hardware has allowed a significant development in Computer-Aided Design (CAD). That also enabled a range of 3D CAD design services. In recent years, software with various applications and tools that can be used have come onto the market to draw and design mechanical parts and systems. Here, you can check out Mechanitec CAD design services.

Also, these 3D CAD programs provide us with a great advantage because they are very educational. After all, through simulation and animation in the designed systems, we can see the efforts and the points where they can suffer some damage. And in this way improve the production of some product in the industry.

3D CAD mechanical design used for engineering product development

engineering product development

Engineers and designers use Computer-Aided Design (CAD) 3D programs to validate and communicate ideas before developing the product.

Mechanical design is the specific field of application and the one in which most applications are marketed due to its scope in different industries, including industrial machine design, the automotive industry, and consumer products.

Three-dimensional (3D) models are used for mechanical calculations and simulations. The simulations largely depend on the type of element to be designed. When designing a vehicle, it is customary to simulate aerodynamic behaviour. In the design of mechanical parts can be studied its bending or the collision between two moving parts. Among the most demanding commercial applications are CATIA, Autocad, and Solidworks.

Creating 3D models and drawings based on hand sketches

Creating 3D models and drawings based on hand sketches

The benefits are almost endless of being able to convert hand sketches into 3D models. We see this every day when we receive very different projects.

Some of the options that a 3D graphic file conversion service allows us are, for example, to create perspective images to register a patent, utility model, or industrial design from a sketch.

Another option is to convert it to a 3D model from a patent or utility model already registered to starting selling the invention. Another idea would be, for example, if you have to present a project to a client but you only have a sketch for a low cost, we can provide you with an image of the whole rendered in 3D at scale.

Other examples would be creating a photorealistic 3-dimensional image, creating a 3D logo from a sketch by adding a metallic texture to it, or 3D printing apart from an STL file of a developed model.

Modelling in 3D CAD systems for the design of parts, devices, equipment, and machines

Modelling in 3D CAD systems for the design of parts devices equipment and machines

Before carrying out any process to manufacture parts, components, or equipment, a design is necessary, which will serve as a guide to make any part. Design draws and ideas objects, constructions, and components allow designers to follow clear instructions and deliver a specific and precise shape.

Performing 3D modelling for system design will help achieve considerable cost savings since it is a safer and more specific process, reducing the possibility of making mistakes or spoiling material. 3D modelling will be the key to the final design.

Specific tools are using for the design of parts, machines, and equipment. 3D CAD is a tool that allows geometric modelling to tailor-made applications to analyze or optimize the product through the calculation of physical properties such as mass, volume, and moment of inertia. This tool’s main objective is to define the geometry design to achieve a unique and precise piece.

Developing 3D models and drawings from the old/legacy drawings (pdf and dwg)


Suppose a manufacturer has to “rebuild” their 2D to 3D design from PDF / DWG formats. Today the tools make it easy to develop 3D models apart from old/legacy drawings.

We must emphasize that working in 3D from scratch allows you to generate files that are ready to go straight to manufacturing operations that require 3D CAD models. In many cases, 2D drawings are not even requiring manufacturing. For example, SOLIDWORKS can create a complete 3D model with detailed dimensioning, tolerance information, and annotations. In this way, all the data and annotations necessary for the manufacture of the piece are included directly in the 3D CAD model. This represents an advantage, for example, when you want to make the maintenance of the machinery.

User guides, assembly instructions, technical reports

Product assembly drawing

Every type of industry has machinery. For this reason, the assembly instructions or user guides present an overview of the device to be built. 

This way, we can see the location of the different parts that compose it, with the relationship and existing concordances between them.

The use of 3D CAD tools in assembly instructions is used to identify all the parts that compose it. That is why each piece must be a mark assigned. These marks are essential for identifying pieces throughout the documentation and manufacturing process.

The user guides or the commissioning of a machine have models (3D) which improve the perception when they need to make maintenance or modifications to the machinery to better understand the indications.

Rendering and 3D CAD Animation

Rendering and 3D CAD Animation

3D rendering is one of the most “striking services” today. It is the process by which, through computer systems, we generate a digital image from a three-dimensional (3D) model or scenario. The goal is to create a realistic picture from any perspective on the model.

It is about generating 3D animation from various processes that allow causing a sensation of depth, allowing to give texture to the different elements of the image to make it more realistic.

Rendering also allows the generation of different lighting effects and photographic techniques. These optical effects are similar or equal to those in the real world when we observe an object, a room, a landscape, or any type of view.

A 3D animation is undoubtedly a tool that serves to see how our design works visually. The visualization is through the use of CAD software through the calculation produced by algorithms and formulas that generate animations on the objects in three dimensions that we have arranged in the scene. And those would be the most common 3D CAD design services.
