Open a new part with model units set tomillimeters.

Go to: File > New > Part

Select the three planes in the feature tree

and make them visible by clicking on the

glasses.

The Front, Top, and Right planes appear,

and the pointer changes to

As you move the pointer over a plane, the border

of the plane is highlighted.

Select the Front Plane and create a sketch by clicking on the 2D sketch icon

The display changes so the Front plane faces you.

The Sketch toolbar commands appear in the CommandManager.

A sketch opens on the Front plane.

Draw a circle

Click at the circle icon on the Sketch toolbar.

The Circle PropertyManager opens in the left pane.

Move the pointer over the origin.

The pointer changes to .

This indicates a coincident relation between the center

of the circle and the origin.

Click to place the center point on the origin.

Move the mouse and notice a preview of the circle dynamically follows the pointer.

Release the mouse and click in the PropertyManager to finish the circle.

Draw another circle at the same way as the last one

The size of your sketch entities does not need to be exact. For example, this circle

does not need to be 61mm. You later add dimensions to specify the size of sketch

entities.

Draw two straight lines

To start a line click at the line icon on the Sketch toolbar.

Click to place the starting point of the line. Move the pointer. Notice that it displays

the current dimensions of the line. Draw the two lines as shown in the picture. The size

of your sketch entities does not need to be exact.

At constraints at the sketch

Select one of the circles and one line and add a tangent relation by clicking on the

tangent icon.

NOTE:

Because a basic knowledge of SolidWorks is required to participate the tutorials

of SolidWorksModel we will left all the small steps in the 2D sketch environment

away in the future.

We do everything we can to keep the SolidWorksModel tutorials as clear and

bright as possible. If we describe every click as above then the tutorial would be

very thick and dull. To prevent this, weve decided that SolidWorksModel

participants should be capable enough to draw a simple 2d sketch with an

example picture of SolidWorksModel like the three examples below.

If you have problems with the 2D sketch features we recommend you to practice

the basics of SolidWorks 2D sketching first.

Here you could find some basic SolidWorks tutorials:

Go to: Help > SolidWorks Tutorials > Getting started > Select a lesson

You could also practice some excellent basic tutorials of SolidWorks itself which

could help you to discover the basics of SolidWorks.

Extrude the sketch

Go to: Insert > Boss/Base > Extrude

Direction : Blind

Change into 88 mm

Select the Thin Feature option

Direction : One-Direction

Change into: 3.5 mm

The yellow selection shows the direction of the extrusion. If you want

to change the direction, click on the red arrow in the Thin Feature

toolbar.
