Home » Creating Extruded Ribs in SolidWorks: A Step-by-Step Guide

In this article, we are going to discuss the steps required to make a rib structure in SolidWorks.

-Briefly introduce SolidWorks and the rib feature, and explain the purpose of the article.

 

Rib design helps structural members survive expected loads, but it has various drawbacks if not properly built. Rib design also causes stress concentration on joints and leaves back sink marks over there. A  proper rib design and construction are critical for achieving low weight, reducing surface flaws, and strengthening the design.

The main uses of the SolidWorks rib feature are designing frames, supports, covers, cabinets, long body components, bearing surfaces in gearboxes, etc.

 

Here are the steps to create a rib in SolidWorks:

  1. Open the SolidWorks model you want to add the rib to.
  2. Select the surface or face where you want to add the rib.
  3. Click on the “Rib” icon in the “Features” tab of the Command Manager or under the “Insert” menu.
  4. Set the rib’s parameters, such as thickness, depth, and draft angle. You can do this in the Rib PropertyManager that appears on the left side of the SolidWorks window.
  5. Choose whether you want the rib to be solid or hollow.
  6. Preview the rib by clicking the “Preview” button in the Rib PropertyManager.
  7. Once you are satisfied with the rib’s parameters, click “OK” to create the rib.

You can also modify a rib’s parameters after it is created by right-clicking on the feature in the Feature Manager and selecting “Edit Feature.”

 

  1. In the new sketch, create an L shape sketch. Here we are creating a sketch using a center rectangle and corner rectangle to make an L shape.
  2. Extrude the sketch and get a shape as shown in the isometric view.
  3. Now create a midplane using the reference plane feature.
  4. As soon as the plane is created, make an open or closed sketch for the rib.
  5. To make a rib click on the rib feature in the command manager.
  6. Then select the sketch and choose the direction.
  7. Click ok to obtain the rib structure.

Note: If you want to make a tapered rib structure then you can also provide a draft angle in the same way as done in extrude feature.

Tips: You can save time by extruding the sketch using a midplane, thus saving time by not creating a reference midplane. It is so because your sketch plane itself acts as a midplane.

Overview of the Rib Feature

SolidWorks is a popular 3D modeling software used in various industries, including product design, engineering, and architecture. It provides a comprehensive set of tools for creating complex 3D models, including features such as extrusions, fillets, chamfers, and more.

One of the key features in SolidWorks is the rib feature, which allows designers to add extra depth and dimensionality to their models by creating thin, extended features that run parallel to a selected edge or surface. Ribs are commonly used to add strength, stability, or aesthetics to a part or assembly, and can be used in a wide range of applications, such as designing machine parts, automotive components, or consumer products. The rib feature can be created in various ways in SolidWorks, such as extruded ribs, swept ribs, and lofted ribs, giving designers the flexibility to create ribs that match their design intent.

Rib Definition

A rib in SolidWorks is a thin, extended feature that runs parallel to a selected edge or surface. It is a tool used in 3D modeling to add extra depth and dimensionality to a part or assembly. Ribs are often used to provide structural support or to enhance the visual aesthetics of a design.

In SolidWorks, ribs can be created using various tools and techniques, including extruded ribs, swept ribs, and lofted ribs. Extruded ribs are the simplest type of rib feature and are created by extruding a sketch along a path. Swept ribs are created by sweeping a profile along a path, while lofted ribs are created by lofting a profile between two sketches. Each type of rib feature provides different options and parameters for customization, enabling designers to create ribs that match their specific design intent.

Ribs are commonly used in a wide range of applications, including machine parts, automotive components, consumer products, and more. They are a valuable tool for designers who want to add extra dimensionality and complexity to their designs, while also improving their structural integrity and overall aesthetic appeal.

Types of Ribs

In SolidWorks, there are three main types of ribs that can be created: extruded ribs, swept ribs, and lofted ribs. Each type of rib feature offers different options and parameters for customization, allowing designers to create ribs that match their specific design intent.

  1. Extruded Ribs: Extruded ribs are the simplest type of rib feature and are created by extruding a sketch along a path. To create an extruded rib, a designer would start by creating a sketch that defines the profile of the rib, and then extrude the sketch along a path to create the rib feature. Extruded ribs offer a variety of customization options, such as adjusting the depth, width, and fillet radius of the rib.
  2. Swept Ribs: Swept ribs are created by sweeping a profile along a path. To create a swept rib, a designer would start by creating a sketch that defines the profile of the rib, and then create a path for the rib to follow. The designer would then sweep the profile along the path to create the rib feature. Swept ribs offer more customization options than extruded ribs, such as adjusting the orientation, twist, and scaling of the rib along the path.
  3. Lofted Ribs: Lofted ribs are created by lofting a profile between two sketches. To create a lofted rib, a designer would start by creating two sketches that define the profile of the rib at the start and end of the rib feature. The designer would then create additional sketches as needed to define the shape of the rib between the start and end sketches. The rib feature is then created by lofting the profiles between the sketches. Lofted ribs offer the most customization options of the three types of rib features, allowing designers to adjust the shape, orientation, and scaling of the rib along its length.

Each type of rib feature can be useful in different design scenarios, depending on the specific needs and design intent of the designer. By understanding the different types of rib features and their unique customization options, designers can use SolidWorks to create ribs that enhance the functionality and aesthetics of their designs.

Creating Swept Ribs and Lofted Ribs

Swept and lofted ribs are two types of rib features in SolidWorks that allow designers to create more complex and intricate designs.

To create a swept rib in SolidWorks, designers would start by creating a sketch that defines the profile of the rib. Next, they would create a path for the rib to follow. The profile is then swept along the path, creating the rib feature. Swept ribs can be useful for creating curved or tapered rib features, such as those found in automotive components or consumer products.

To create a lofted rib in SolidWorks, designers would start by creating two sketches that define the profile of the rib at the start and end of the rib feature. Additional sketches are then created as needed to define the shape of the rib between the start and end profiles. The rib feature is then created by lofting the profiles between the sketches. Lofted ribs can be useful for creating more complex or organic rib features, such as those found in medical devices or consumer electronics.

Swept and lofted ribs offer greater customization options than extruded ribs, and can be used to create more complex rib features that match the designer’s specific design intent. They are often used in designs where aesthetic appeal is important, such as consumer products or architectural models. They can also be used in designs where structural support or stability is needed, such as machine parts or industrial equipment.

Tips and Tricks for Using Rib Features in SolidWorks

Here are some best practices and tips for using rib features effectively in SolidWorks:

  1. Avoiding Common Errors: When creating ribs in SolidWorks, it’s important to ensure that the rib features are properly constrained and aligned with the rest of the model. Common errors when creating ribs include accidentally deleting constraints, improperly defining the rib profile, or not properly aligning the rib with the rest of the model. To avoid these errors, it can be helpful to double-check the constraints and alignments at each step of the rib creation process.
  2. Combining Rib Features with Other Tools: Rib features can be combined with other SolidWorks tools and features to create more complex and detailed designs. For example, ribs can be combined with fillets and chamfers to create smoother transitions between different parts of a design. Similarly, rib features can be combined with loft features or surfaces to create more complex shapes and contours. Experimenting with different combinations of tools and features can help designers to create more intricate and detailed designs.
  3. Optimizing Rib Features for Manufacturing or 3D Printing: When creating rib features, it’s important to consider the manufacturing or 3D printing process that will be used to produce the final product. For example, ribs that are too thin or too thick may not be suitable for certain manufacturing processes, such as injection molding. Similarly, ribs that are too complex or intricate may be difficult to produce using certain 3D printing techniques. Designers should consider the limitations and requirements of the manufacturing or 3D printing process when creating rib features, and optimize their designs accordingly.

By following these best practices and tips, designers can use rib features effectively in SolidWorks to create more complex and detailed designs, while also avoiding common errors and optimizing their designs for manufacturing or 3D printing.
