What is an OBJ file?

Obj is an open file format widely used in 3D graphics.

It’s a simple data-format that stores information about a 3D model’s geometry, including its vertices, faces, vertex normals and UV position of each texture coordinate vertex in case of texture applied.

OBJ files are widely supported and exportable by most 3D design software. This is because they are simple and realistic, especially when used with a MTL material file.

OBJ Files offer many advantages, such as:

1. Compatibility:
   • One of the primary advantages of OBJ files is their compatibility with a broad range of 3D modelling and rendering software. This interoperability makes them a preferred choice for users working with diverse tools.
2. Human-Readable Format:
   • Being a plain-text format, OBJ files are human-readable, making it relatively easy to understand and even modify using a simple text editor. This readability enhances accessibility and facilitates collaboration.
3. Versatility:
   • OBJ files are versatile and support various types of geometry, including polygons of different complexities. This versatility allows them to represent a wide range of 3D objects.
4. Texture Mapping:
   • OBJ files support texture coordinates, enabling the mapping of textures onto 3D models. This capability is essential for creating realistic and visually appealing renders.

While OBJ files offer numerous advantages, some challenges should be considered when working with them:

1. File Size:
   • Because OBJ files are human-readable (plain-text format), they can become large when storing complex models with high polygon counts. Large file sizes can impact storage, transfer times, and system performance.
2. Limited Material Information:
   • OBJ files may not fully capture all material properties, especially in comparison to more advanced formats like FBX or COLLADA. Users may need to rely on associated MTL files for additional material details.
3. No Animation Support:
   • Unlike some other formats, OBJ files do not inherently support animations.

Difference between OBJ and STL

The STL file lacks texture, materials, and normal information, making the 3D model look less realistic compared to an OBJ file.

Despite both formats are widely adopted and can be used in additive manufacturing processes such as 3D printing, the main difference between them is presented below: 

1. Information Depth:
   • OBJ: Emphasizes comprehensive information, including geometry, texture coordinates, normals, and material details. Suitable for various applications where a detailed representation is essential.
   • STL: Primarily focuses on surface geometry, providing a mesh representation without detailed information about vertices, texture mapping, or material properties. Suited for 3D printing applications where only surface geometry matters.
2. Geometry Representation:
   • OBJ: Utilizes vertices, faces, normals, and texture coordinates to define the 3D geometry. Well-suited for representing complex and detailed models in various industries.
   • STL: Relies on a mesh of triangular facets to represent the surface geometry. This simplicity makes STL files efficient for 3D printing but less suitable for detailed visualizations.
3. Material Support:
   • OBJ: Supports material information through associated MTL files. Capable of representing color, shininess, transparency, and texture references.
   • STL: Does not inherently support material information. Material properties are typically managed separately during the 3D printing process.
4. Applications:
   • OBJ: Widely used in CAD, 3D animation, VR, AR, and game development due to its versatility and ability to encapsulate detailed information about 3D models.
   • STL: Primarily used in 3D printing and rapid prototyping applications where only the surface geometry is critical. Less versatile for applications requiring comprehensive model information.
5. File Size:
   • OBJ: Can result in larger file sizes, especially for complex models with high polygon counts and detailed textures. Larger file sizes may impact storage, transfer times, and system performance.
   • STL: Generally has smaller file sizes due to its focus on surface geometry. Compact file sizes contribute to faster transfer times and reduced storage requirements.

The choice of the right format therefore depends on many factors such as:

1. Complexity of the Model:
   • OBJ: Ideal for complex and detailed models where comprehensive information about geometry and appearance is crucial.
   • STL: Well-suited for models where only surface geometry matters, such as those intended for 3D printing.
2. Application Requirements:
   • OBJ: Suitable for applications that require a detailed and versatile representation of 3D models, including visualizations, animations, and simulations.
   • STL: Specifically designed for 3D printing applications, where the emphasis is on efficiently representing the surface geometry for additive manufacturing.
3. Ease of Use:
   • OBJ: Offers a human-readable format, making it easier to understand and edit using a simple text editor. Accessibility is a key advantage.
   • STL: Known for its simplicity and compatibility with 3D printers, providing a streamlined process for 3D printing applications.

What is a STEP file?

Step files represent 3D objects made with CAD and show their structure and properties.

The STEP file format is a widely used standardized format in product manufacturing, also known as ISO 10303. This format is considered the best for exchanging data between CAD systems such as Solidworks, CATIA, and AutoCAD.

There are many advantages in using STEP Files in engineering and manufacturing:

1. Interoperability:

   One of the primary advantages of STEP files is their ability to facilitate interoperability between various CAD systems. Different software applications may have proprietary file formats, making it challenging to share models seamlessly. STEP serves as a bridge, enabling designers and engineers to collaborate across different platforms.

2. Data Preservation:

   STEP files store not only the geometric information of a 3D model but also its metadata, such as materials, assembly structure, and other product-related data. This comprehensive data preservation ensures that critical information is not lost during file conversion or transfer.

3. Standardization:

   As an ISO standard, STEP provides a consistent and standardized way to represent product data. This ensures that data interpretation is uniform across different software applications, reducing the chances of errors and miscommunications in the design and manufacturing process.

Understanding the Structure of STEP Files:

STEP files are organized into modules, each serving a specific purpose. The two primary modules are:

1. Geometry (B-Rep): The geometry module represents the 3D shape of the model using B-Rep (Boundary Representation). B-Rep defines the surfaces, curves, and topology of the 3D object, allowing for an accurate representation of its form.

2. Product and Manufacturing Information (PMI)

   Complementing the geometry module is the Product and Manufacturing Information (PMI) module. PMI encapsulates data related to the product beyond its visual representation. This includes information about the assembly structure, materials, tolerances, annotations, and other details crucial for manufacturing and product lifecycle management.

   • Assembly Structure:

     The assembly structure within the PMI module outlines how individual components come together to form the complete product. This hierarchical representation is vital for understanding the relationships between different parts and their positioning within the overall assembly.

   • Materials and Textures:

     STEP files can store information about the materials used in the design, allowing for a more realistic representation of the model. This is especially important in industries where material properties play a significant role in the product’s functionality.

   • Tolerances and Annotations:

     PMI includes details about tolerances, annotations, and other manufacturing specifications. These annotations provide additional information about the design intent, helping manufacturers and engineers understand critical aspects of the product.

While STEP files offer numerous advantages, some challenges should be considered when working with them:

1. File Size:

   Depending on the complexity of the model and the amount of metadata included, STEP files can become large. This may pose challenges in terms of storage, file transfer, and system performance. For the best performance with the STEP Viewer, we suggest to reduce the number of parts whenever possible.

2. Loss of Advanced Features:

   Some CAD systems have advanced features and functionalities that may not be fully supported by the STEP format. Users should be aware that certain proprietary attributes might be lost during the conversion process. To check if all the desired features have been exported and therefore can be correctly visualised in the STEP Viewer, try to open the exported STEP file with multiple CAD packages. 

STEP files are used in multiple applications and industries:

1. Automotive Design and Manufacturing:

   In the automotive industry, where collaboration among multiple stakeholders is essential, STEP files streamline the exchange of design data. From the intricate geometry of vehicle components to manufacturing specifications, STEP facilitates a seamless workflow.

2. Aerospace Engineering:

   Aerospace projects involve complex assemblies with stringent tolerances. STEP files are instrumental in conveying not only the geometric intricacies of aircraft components but also the precise manufacturing information required for aerospace engineering.

3. Consumer Electronics:

   The consumer electronics industry relies on rapid innovation and collaboration. STEP files enable the exchange of detailed 3D models, ensuring that designers, engineers, and manufacturers can work together effectively to bring cutting-edge products to market.

A 3D model review is a part of the 3D design review process, where a 3D digital representation of a physical object is evaluated for accuracy, completeness, and adherence to design specifications and standards. 

During a 3D model review, a team of experts examine the 3D design from various angles and perspectives, and identify any issues, limitations, or potential problems. The review team may also provide feedback to the design team on areas where improvements can be made to enhance the overall quality and functionality of the design. 

The goal of a 3D model review is to catch any mistakes or oversights before the design is finalized and put into production, ensuring that the final product is of high quality and meets the requirements and expectations of the stakeholders.

What are the typical activities of a 3D model review?

Typical activities involve organizing meetings with the review team where usually the 3D content under review is shared by a single member of the team which has access to the 3D data and to the 3D software package. This can be challenging from a technical point of view, especially for small companies, and limits the scope of the team members with no direct access to the 3D data, as they are not free to inspect the 3D design as they could.

How can you review with 3DVieweronline?

This is why 3DVieweronline simplified the review process by building the 3D Viewer, an inexpensive and easy to use web service solution which allows businesses to collaborate on 3D models. The 3D Viewer allows each member of the review team to access the 3D data without the need of any CAD software, high-end computers and without any previous 3D software skill. The powerful communication tools furthermore, allow each team member to write comments, create markups and attach support documentation for a better and quicker exchange of feedback.   

Reviewing 3D models with 3DVieweronline requires only a few simple steps:

• Log in (or create a free account) and upload the 3D model you want to review
• Click on the comment icon to load the 3D model with the collaboration tools enabled. This will allow you and anybody else collaborating to review the 3D design by creating comments and markups

GrabCAD workbench was introduced back in 2012, giving students and engineers a platform to share and collaborate on CAD models. The tool allowed its users to easily access CAD models, such as STEP, IGES or native CAD file formats, just with a web browser. Among the many appreciated features offered, there was the possibility to take measurements, create markups and communicate to get quick feedback from customers. 

When will GrabCAD workbench be discontinued?

On June 1st 2023 (12PM GMT), GrabCAD workbench will be discontinued as the company’s primary focus is now shifting more and more towards additive manufacturing.

Why is 3DVieweronline a good GrabCAD workbench alternative?

A CAD (Computer-Aided Design) file is a digital representation of a design or object created using specialized software. It contains all the necessary information to accurately describe the geometry, size, shape, and other features of a physical object or product, as well as its intended function, performance, and behaviour.

CAD files are used across a range of industries, such as engineering, architecture, product design, and manufacturing, to create, visualize, and analyse designs, as well as to communicate design information between different teams and stakeholders.

There are different types of CAD files, such as 2D CAD drawings, 3D models, and parametric models, each with their own specific features and capabilities. They are commonly saved in standardized file formats, such as STEP, IGES, DXF or DWG, to ensure compatibility between different CAD software systems. 

3DViewerOnline accepts most 3D neutral CAD formats, such as STEP and IGES, and most 2D CAD drawing formats such as DXF and DWG. 

Traditionally, viewing a CAD file required 3D modelling and visualisation software that needed to be installed on a local computer able to run it, meaning with the minimum system requirements and with the proper administration rights. Without a good knowledge of 3D software furthermore, the learning curve to simply open it could be quite steep, since there are many software settings to configure before starting.
