Hi friends, welcome to SolidWorks tutorials for beginners and in this tutorial post, you can see how to use SolidWorks boundary boss feature tool. Boundary boss or base tool is also like the other boss features such as Extrude boss, Revolve Boss, Swept Boss, Loft Boss etc; but much more advanced tool in terms of SolidWorks CAD applications. It helps to create complex designs which can’t be creating using other boss feature tool. In this tutorial I am going to share about SolidWorks boundary boss or base and a step-by-step example for using it in this CAD software.

What is SolidWorks Boundary Boss or Base and How to Use it?

SolidWorks Boundary Boss or base is tool used to create feature by adding material in two directions. That means, you can add materials between two profiles between two boundaries. Loft boss is also like Boundary Boss feature, but it adds materials between two profiles. As compared to Loft boss, Boundary boss helps to add materials between two direction, even between two solid features. It helps to create more complex designs even curved bodies which is very difficult to create with Swept boss. Checkout Best SolidWorks Training Materials here.

In this example, I going to show you how to apply boundary boss or base feature tool to two sketch profile. Here, I am going to create one closed profile (e.g: circle, Rectangle or polygon) and one open sketch (curve) profile. Then, I will show you how to apply this feature tool to these sketch profiles.
