Revolved Boss or Base is a SolidWorks feature tool which is used to create solid 3D model around an axis. You can revolve the sketch around an axis to add materials to it. You can access revolved boss/base from both command manager and menubar. Like the SolidWorks extrude boss/base feature, you can also add materials in one or two directions, while revolving it.

Using this feature, you can create solid rings, hollow cylinders, pressure vessels, solid and hollow spheres, power transmission pulleys etc. You see the applications of each feature in our upcoming tutorial posts. Now you can see the hollow cylinder creation exercise using Solidworks revolved boss/base feature.

How to Use Revolved Boss/Base Feature on Sketch

I’m going to create hollow cylinder of dimensions and image are give below.


Outer Diameter (OD) = 50 mm
Inner Diameter (ID) = 30 mm
Length of hollow cylinder (L) = 100 mm

Step-1: New Part File

Open the SolidWorks and New part File. If you don’t know it, read how to create new part File. Select the Plane (e.g. Top Plane) and normalize using the “Normal To” Button. Also Read SolidWorks Heads-up Toolbar on this blog.


Step-2: Draw Reference Axis

Go to the sketch and select line or center line. I prefer centerline sketch tool, because it is look like centerline engineering graphics representation and also used as axis. Select it from command manager and draw centerline of any length, vertical or horizontal. It’s up to you.

Step-3: Draw Sketch

To create a hollow cylinder, you need to revolve a rectangle around an axis. The “OD, ID and L” dimensions are given below.
Draw rectangle by using rectangle or line sketch tool and use smart dimension to make it in proper size.


Hollow cylinder thickness (t) = OD – ID = 50 – 30 = 20 mm.

Step-4: Select Revolved Boss/Base Feature

First you need to “Exit Sketch” by clicking Red Cross button at top right corner of SolidWorks graphics area or click “Exit the Sketch” in the sketch command manager.

Select the sketch from the featuremanager design tree. Here I select “Sketch-1”.

From command manager, you can select the Revolved Boss/Base button is look like thissolidworks-revolved-boss or base-button

In Direction 1, you can control the material adding direction. Here I select “Blind” and angle is 360 degree to make hollow cylinder.
Click Green Tick button (OK) in property manager to complete the 3D drawing of hollow cylinder.
