A Step-by-Step Guide to Creating Complex Surface Models in SolidWorks

Authored By: Ankita Prajapati

Creating complex surface models in SolidWorks can be challenging, but it’s an essential skill for many product designers and engineers.

In this tutorial, we will walk you through a step-by-step guide to creating complex surface models in SolidWorks.

Step 1: Sketching the Basic Shape

The first step in creating a complex surface model is to sketch the basic shape using the Sketch tool in SolidWorks. You can create sketches on the surface of a model or on a plane. 

Use the different Sketch tools to create lines, arcs, circles, and other shapes to create the basic form of your model.

Step 2: Creating Curves

Next, you will need to create curves using the Curve tool in SolidWorks. Curves are essential for creating complex surface models because they define the shape of the surface. 

Use the different Curve tools to create lines, splines, arcs, and other curves to define the complex shape of your model.

Step 3: Creating Surfaces

Once you have created your curves, you can use them to create surfaces using the Surface tool in SolidWorks. 

Surfaces are 2D shapes that can be used to create 3D models. Use the different Surface tools to create planar, cylindrical, and spherical surfaces to define the shape of your model.

Step 4: Trimming Surfaces

After you have created your surfaces, you can trim them using the Trim Surface tool in SolidWorks. 

Trimming surfaces is essential for creating complex shapes because it allows you to remove unwanted portions of the surface. Use the Trim Surface tool to remove any unnecessary portions of the surface and refine the shape of your model.

Step 5: Creating Fillets and Chamfers

After you have created your surfaces and trimmed them, you can add fillets and chamfers using the Fillet and Chamfer tools in SolidWorks.

Fillets and chamfers are used to create rounded edges and angles on the surface of your model. Use the different Fillet and Chamfer tools to create the desired edge and angle features of your model.

Step 6: Adding Thickness to Surfaces

Once you have created your surfaces, trimmed them, and added fillets and chamfers, you can add thickness to the surfaces using the Thicken tool in SolidWorks. 

Adding thickness to surfaces is essential for creating solid models that can be used for manufacturing. Use the Thicken tool to add the desired thickness to your surfaces and create a solid model.

Step 7: Checking for Errors

Finally, you will need to check your model for errors using the Check tool in SolidWorks. 

Checking your model for errors is essential to ensure that your model is suitable for manufacturing. 

Use the Check tool to identify any errors or potential issues with your model and make the necessary corrections.


Creating complex surface models in SolidWorks requires a combination of sketching, curve creation, surface creation, trimming, filleting, chamfering, adding thickness, and error checking. 

By following these steps, you can create complex surface models that are suitable for manufacturing and meet the desired design specifications.
