# How To Use Lofted Boss/Base In Solidworks(Illustrated Expression)

In this article we will show the what is Lofted Boss/Base comman in Solidworks and how is the use of Lofted Boss/Base command in Solidworks, what are the features of Lofted Boss/Base command in Solidworks and what kind of geometries could be obtained by using of it. Lofted Boss/Base command is generally used for obtaining 3D geometries utilizing from various 2D sections in different planes. You could obtain very aesthetic 3D geometries by using Lofted Boss/Base command.

## How The Lofted Boss/Base Command Is Used In Solidworks?

From the example above, you can see the different 2D sections that obtained different planes in Solidworks and these 2D sections are connected to each other with a 3D sketched guide line. We could use Lofted Boss/Base to obtain a 3D geometry. Click on the Lofted Boss/Base command as shown by red arrow above.

In Lofted Boss/Base command, the profiles are selected in the red box, and the selected profiles for lofting are shown by red arrows above. And the guide curves(you do not need to select guide curves for Lofted Boss/Base) selecten in green box above, and selected guide curve is shown by green arrows.

If you want to obtain pipe-like Lofted Boss/Base geometry, you could select the Thin Feature in the Lofted Boss/Base command, then you need to specify your geometry’s thickness.

The understanding of curvature in Solidworks could be somewhat hard. You could select extra curvature visualizers such as mesh preview or zebra stripes etc. you could view the curvature on your geometry by Lofted Boss/Base command in Solidworks.

If you completed your adjustments in Lofted Boss/Base command, you need to click on the green yes symbol as shown by green arrow above.

This is our final geometry that obtained with Lofted Boss/Base command. You could see the difference between guide curve used side(shown by red arrow above), non-guide curve is used side(shown by green arrow). And also our geometry is hollow because of we selected Thin Feature.
