Solidworks is a common mechanical engineering software for drawing and detailing, In this tutorial, you will draw the sketch of the model shown in Figure 1. The sketch is shown in Figure 2. You will not dimension the sketch. The solid model and the dimensions are given only for your reference. The steps that will be followed to complete this tutorial are listed below: 1. Start SolidWorks and then start a new part document. 2. Maximize the part file document and then switch to the sketching environment. 3. Draw the sketch of the model using the Line and the Circle tools, refer to Figures 4 through 7. 4. Save the sketch and then close the document. Starting SolidWorks and Starting a New Part Document, Setting the Units and Grid, Drawing the Outer Loop of the Sketch It is a good practice to draw the sketch on one side of the origin, preferably in the first quadrant. This is because while generating the part program for manufacturing the part, you will have a reference for work origin in advance. You will start drawing the sketch from the lower left corner of the sketch and the outer; loop will be drawn using the continuous lines. Drawing the Sketch of the Inner Cavity Next, you will draw the sketch of the inner cavity. To draw the sketch of the inner cavity, you will start drawing with the lower horizontal line. Modifying the Snap and Grid Settings and the Dimensioning Units Before you proceed with drawing the sketch, you need to modify the grid and snap settings so that you can make the cursor jump through a distance of 5 mm instead of 10 mm, which is the default value. Saving the Sketch, Creating Revolved model To create a 3-D Model from the Base sketch shown in Figure 3, we will first draw an axis of revolution and then revolve the sketch around the axis. An alternate approach to draw the Base sketch shown in Figure 2. In SolidWorks we may complete the sketch following different approaches. The same sketch shown in Figure 2 will be drawn using another approach.
