SolidWorks 2010- P12: Whether you are a new user of SolidWorks or a professional who wants to improve your skills, this book was written for you. Learning any software can be difficult at times. You launch the software for the first time, and you feel overwhelmed, not knowing how to even start a new document. In 3D CAD programs, it can be especially difficult. Many times a whole new vocabulary and a whole new creative environment are introduced. | Create a Swept Feature 299 Create a Path for Swept Feature Sometimes it does not matter which comes first the path or the profile when creating the sketches for a swept feature but we often find it is easier to create the path first. The path for a swept feature can be a single sketch consisting of a set of curves a single curve or even a set of model edges. The path for a swept pattern must not intersect itself and it can be made up of continuous segments only. The path must also intersect the plane of the profile. By creating the path first you can ensure that the profile plane is normal to the end of the path and it also gives you a good point to work from in your profile sketch as you will see. The path for the arm of the shade mount is a simple path that will consist of two lines that are connected with a tangent arc or fillet. To create the path on the sketch plane that was added in the previous section do the following WARNING Be careful when sketching the path to ensure that the resulting solid is not self-intersecting. This can often be caused by an angle in the path that is too acute or a radius that is too small. 1. Select the new plane Planel and click the Sketch button on the context toolbar. 2. Select Normal To in the Heads-Up View toolbar. 3. Create a line that originates at the sketch origin and draw it horizontally to the right about 5 inches long as displayed next to the mouse pointer. Click and release the left mouse button. 4. Drag the mouse pointer up vertically to create another sketch segment that is approximately long. Click and release the left mouse button to draw the line. Press Esc on your keyboard or double-click the left mouse button to exit the Line command. 5. Using the Smart Dimension tool apply the dimensions shown in Figure . 6. Select the Sketch Fillet command and specify the radius in the Sketch Fillet PropertyManager to be . 7. Select the corner where the two sketch lines meet to create the fillet. Click the
