Designing plastic parts is a common practice in consumer product design due to their durability, versatility, and inexpensiveness when produced in high volumes. SOLIDWORKS is a popular software used for plastic part design, offering a range of tools to simulate and optimize the design process. One technique used in SOLIDWORKS is debossing, which involves removing material from a surface to create a desired effect. This process can be applied to curved surfaces, and understanding the steps involved is crucial for achieving the desired outcome. By utilizing the wrap feature, reference geometry, and specific methods, designers can effectively deboss plastic parts in SOLIDWORKS, enhancing the functionality and aesthetics of their creations.

What You'll Learn
Creating a deboss on a curved surface
To create a deboss on a curved surface in SolidWorks, you can follow these steps:
First, start by creating an offset plane—front, top, or right, depending on what makes the most sense for your specific design. You can do this by using the Features toolbar and adding a reference plane offset from the existing plane, or by using the CTRL+drag function to add a plane offset.
Next, start a sketch on this new plane. Create a spline for the text to follow by converting it into a series of construction entities. You can add text to your sketch via the Sketch toolbar. The text can follow any curve you would like, and you can choose how the text aligns itself (right or left).
Now, you can choose to have the text placed at the bottom or top of the curve and adjust the font and depth as needed. To emboss or deboss, use the Wrap feature found in the Features toolbar. Grab the text and the sketch you have created, and this will give you the ability to add or remove material.
By default, emboss and deboss will extrude the feature normal to the sketch plane, but you can specify a pull direction to change the extrusion direction. You can select a line, linear edge, or plane to specify the pull direction.
Additionally, if you are working with a complex surface, you can use the Spline Surface command. Then, take the sketch and deboss it onto the face of the curved surface.
It is important to consider the manufacturing process when designing a deboss on a curved surface, especially if it is a part of a logo or design that will be injection molded. Keep in mind how the mold will be split and where the parting line will be to ensure your design can be manufactured effectively.

Using the wrap tool
The SOLIDWORKS Wrap tool is a powerful feature that allows users to create artwork, text, and geometry on virtually any surface of a model. It is particularly useful when working with curved surfaces, where traditional tools like the Extrude tool fall short. The Wrap tool acts as a replacement for the Boss Extrude and Cut Extrude tools, allowing for more flexibility in the application of 2D geometry to a surface.
To use the Wrap tool effectively, follow these steps:
Step 1: Create a Reference Sketch
Start by creating a reference sketch on the face you want to use the Wrap tool on. This sketch can be a simple circle, rectangle, or any other closed contour sketch. For complex designs, ensure that the sketch will follow the circumference of the cylinder or surface to achieve the desired "wrap" effect.
Step 2: Exit the Sketch and Select the Wrap Tool
Once your sketch is complete, exit out of it and select the Wrap tool. The Wrap tool icon will be displayed, and you will be ready to use it.
Step 3: Choose the Wrap Type
In the Property Manager, select the Wrap Type. For debossing plastic, you would choose the “Deboss" option. The Deboss wrap type will imprint or cut the feature into the face of the plastic, creating an indented design.
Step 4: Select the Face for Wrap
In the Feature Manager, select the face of the cylinder or curved surface you want your sketch to be wrapped onto. This is where your design will be applied.
Step 5: Adjust Wrap Parameters
Fine-tune the wrap parameters, including the source sketch, face for wrap, and thickness. Ensure that the preview of your design on the selected face looks as desired.
Step 6: Finalize and Review
Once the parameters are set and the preview meets your expectations, press the green checkmark to finalize the process. You will then see the final product, with your sketch successfully debossed onto the plastic surface.
The SOLIDWORKS Wrap tool offers a simple yet versatile solution for applying designs to curved surfaces. By following these steps, users can effectively deboss plastic in SOLIDWORKS, creating intricate and precise imprints on their models.

Creating reference geometry and planes
To create reference geometry and planes in SOLIDWORKS, you must first draw a closed contour sketch on the reference plane. This sketch should have a dimension controlling the overall length, with the value of this dimension set equal to the circumference of the part using a simple equation. This guarantees that the Wrap feature will cover the whole circumference of the cylindrical face.
Once you've exited the sketch, the setup is complete, and you can move on to using the wrap tool. There are several wrap types available in the Property Manager: emboss, deboss, and scribe. The emboss option adds material, deboss removes material, and scribe splits the face following the sketch contour. You can also choose between two wrap methods: analytical and spline surface. The analytical method is used when you want the extrusion to wrap around the model, and by default, emboss and deboss will extrude the feature normal to the sketch plane. However, you can specify a pull direction to change the extrusion direction by selecting a line, linear edge, or plane.
If you're working with a curved surface, you can create a deboss effect by following these steps: split the line of the shape, do a surface offset, and delete the front face. You can then try knit and fill surface, or use extrude cut as a temporary solution. Alternatively, you can try building up an enclosed space with surfaces and trims, knitting them into a solid, and then merging. Another method is to make an offset surface on the back side with zero offset, use the same sketch to cut a hole where the deboss is, and then hide the solid body. Use surface trim to combine the surfaces into one "block", thicken it to make it a solid, and combine it with your original body.

Using the extrude feature with offset option
To deboss plastic in SolidWorks, you can use the Extrude feature with the Offset option. This allows you to offset an extrusion (emboss or deboss) from a face, edge, or vertex. This is useful when you need to maintain certain dimensions or make changes without having to constantly double-check measurements and do extra calculations.
- Start by opening a new part and setting the model units to millimeters.
- Select the Top Plane in the feature tree (found on the left menu) and create a sketch by clicking on the 2D Sketch icon. This will change the display so that the Top plane faces you.
- Create a sketch that starts at the origin. You can change the dimensions of the rectangle by clicking on the dimension button. For example, you can set the dimensions to 100 and 150 mm.
- Set Direction 1 to Blind. Using the Blind feature will give you a solid extrude.
- Now, you can use the Offset From Surface option under the Extrude feature. This allows you to extrude a shape until a specific distance from another surface.
- Specify the offset distance you want for your deboss. This will determine how deep the deboss will be.
- Follow the steps provided by SolidWorks to complete the extrusion with the specified offset.
- If you are working with a curved surface, you can use the Spline surface option to project your sketch onto the complex face. Keep in mind that this option will not wrap around the model.
- By default, the deboss will extrude the feature normal to the sketch plane. However, you can specify a pull direction to change the extrusion direction. You can select a line, linear edge, or plane to define the pull direction.
- Once you have set the offset distance and direction, complete the extrusion process.
- After the extrusion is complete, you might need to use additional features to clean up the model. For example, you can use the "delete/keep body" option to remove any unwanted letters or features.
By following these steps, you can use the Extrude feature with the Offset option in SolidWorks to create a deboss on a plastic part with the desired depth and direction.

Projecting curves and moving faces
To create a projected curve using the "Sketch on Sketch" method, you need one sketch and one face or surface where the curve will be projected. This method involves creating two different sketches in two different planes, with the intersection between the sketches converted into a projected curve. The "Sketch on Sketch" option is ideal for crafting complex surface models. For instance, consider SolidWorks' three default planes: Front, Top, and Right. These three planes provide eight quadrants in which to create 2D sketches.
Another approach to projecting curves is the "Sketch on Face" option. This method projects a sketch onto a complex face without wrapping around the model. This is particularly useful when you want to project a design onto a specific area of a model without it continuing onto other faces. By selecting a line, linear edge, or plane, you can specify the pull direction to control the extrusion direction.
When it comes to moving faces in SolidWorks, the "Move Face" command is essential. This command allows you to offset faces with a 0 offset (srf offset command) and then use cut-thicken to create the desired depth for your design. This technique is particularly useful when working with debossing or embossing, as it enables you to manipulate the distance between the face and the plane.
By combining the skills of projecting curves and moving faces, you can create intricate and detailed designs in SolidWorks. These techniques offer flexibility in customizing the depth, direction, and placement of your designs, making them valuable tools for any SolidWorks user.
