SolidWorks Exercises-1: Circle Sketch and Extrude Boss Feature

For learning SolidWorks features in detail, need to do some exercises with each feature tools. This post is about SolidWorks Exercises for creating different shapes using extrude boss tool and circle. Here I am going to show basic 3D shapes such as cylinder and cone. In each shape tutorial, I will show the different applications of extrude boss/base property manager also.

3D Cylinder Exercise

Dimensions of Cylinder: Diameter = 50 mm and Length = 100 mm

Step-1

Create a New Part File and Select the any plane. Here I’m select the “Top Plane”, like all other previous tutorial.

Checkout Best SolidWorks Training Materials here.

Step-2

For creating a cylinder using extrude boss, need a circle sketch profile. If you do not know, how to do it, see SolidWorks Circle Drawing Tutorial here.

Using Circle button, draw it on the sketch area and then use the smart dimension to set the diameter of the circle is 50 mm, which is shown in the figure below.

Step-3

“Exit the Sketch” and Select the “Sketch-1” from the Featuremanager design tree. Then go to “feature command manager” and select the “Extrude boss/base” button from it.

Step -4

Then you can see light yellow color preview of cylinder or circle extrusion with Extrude boss property manager.

Then final 3D cylinder of dimension 50mm diameter and 100 mm length will look like on the below post.

3D Cone Exercise

Here I’m going to convert previously created 3D cylinder into a 3D cone, without changing its dimensions. You can create cone by using Revolved boss will discuss later. Let us see exercise for creating 3D cone using Extrude boss/base feature.

If you want to create cylinder in new part file, Follow Step 1 to 4 in the previous tutorial.

Here I going to edit the 3D cylinder extrude boss.

For editing the features, go to featuremanager design tree and select the Extrude Boss.

Click right button of your mouse, then you can see a menu. From that select “Edit Feature”.

Then the Boss Extrude property manager will again appear. From that click on “Draft on/off” button. Then you need to enter the draft angle in next column which is shown in the figure.

To get draft angle, you know the cylinder height (100 mm) and radius (25 mm).

By using trigonometry, tan Ө = 25/100. Then Ө = tan^-1 (4) = 14 degree draft found by calculation.

You can also click on the “draft Outward” option at same draft angle which is shown below.

The draft inward get 3D cone as final.
