Confirm the circular pattern command.įigure 5.20 Circular Pattern of. To do this, be sure that the 3/8 of an inch hole is selected in the “Features and Faces to Pattern” selection box and the center hole of the part is selected in the “Pattern Axis” selection box of the property manager. 375-inch hole at the top quadrant of the construction circle and confirm the hole wizard command.Īctivate the Circular Pattern command from the features tab of the CommandManager and pattern the circle 5 times equally spaced around the center of the part. Remember that you can change the circle to construction from the property manager (“For Construction” Option) as well as by clicking the circle and selecting “Construction Geometry” from the context toolbar.Īctivate the point command again to place the. Switch to the positions tab, click the back inside face of the part, activate the circle sketch command and place a 1.5-inch construction circle at the origin of the sketch. Switching the “Show Decimal Values” also helps when you aren’t sure of the drill size. Switching to the Fractional Drill Size hole type helps find the hole size faster. Start the hole wizard a second time and specify a 3/8 of an inch hole (.375) that goes through the entire part. Finally, add a midpoint relation to the centerline and the point for the tapped hole. ![]() Then CNTRL-click the front endpoint of the centerline and the origin and specify an “Along Y” relation. To create a revolve feature: Create a sketch that contains one or more profiles and a centerline, line, or edge to use as the axis around which the feature revolves. Click the centerline and in the context toolbar, specify an “ Along Z” relation. Place the hole near where we desire it, draw a centerline from the front edge to the back edge of the 1-inch diameter face. Switch to the positions tab and select the 1-inch outer diameter face as the face to place the hole on. Start the hole wizard feature command from the CommandManager and specify a 10-32 Straight Tapped Hole that goes up to the next surface (Up to Next) and a nearside countersink of. ![]() Hole Wizard Holes Figure 5.17 10-32 Tapped Hole Type Settings Start a new part and complete the revolve feature of the CAE1004 Flywheel. You should see a yellow preview of the revolved feature revolving 360 degrees the profile of the sketch we just drew. Select the Revolved Boss/Base tool from the features tab and then confirm the feature. This is acceptable but if it really bothers you like it does me, you can add a relation between the centerline endpoint and the overall width edge of the sketch. 400-inch width and the 1.030-inch width by selecting the vertical lines that represent the width.Įnsure that your sketch is fully defined after adding these dimensions (except for the center line endpoint which will remain underdefined. 5-inch diameter, the 1-inch diameter, the 2-inch diameter, and the 2.66-inch diameter. But when you move your cursor below the centerline, the dimension becomes a diameter. When your cursor is above the centerline, the dimension will only show as a radius. Place diameter dimensions by selecting each horizontal line of the sketch and the center line. The sketch should look like a blocky letter “S”. Make your sketch as proportional as possible to the actual geometry seen in the drawing. Sketch above the centerline a rough outline of the top portion of the section view shown in the drawing excluding all holes. The length of this line does not matter.įigure 5.13 Centerline for Revolve Sketch ![]() Lastly, if you created the dimensions this way, and created a radius dimension instead of a diameter, or vice versa, you can change how it is displayed. This double dimension technique is not restricted to just revolve feature sketches. The Revolveĭraw a horizontal centerline from the origin to the right. Once you create the revolve feature from this sketch, the system will automatically add the diameter symbol. CAE1004_Flywheel was designed in inches so be sure your units are set to inches. Open a new part in SolidWorks and start a new sketch on the Right Plane by right clicking on the right plane and selecting the sketch icon. ![]() In a sketch that contains two or more centrelines, you will need to manually select the Axis of Revolution.CAE1004 Flywheel Tutorial Figure 5.12 Finished CAE1004 Flywheel If a sketch contains a single centreline, SOLIDWORKS will automatically select it to revolve around. There are certain rules that should be followed when creating a sketch for a revolve.Ī centreline, axis, sketch line or linear edge must be specified as the axis of revolution. We’ve essentially just taken half the section view from the above drawing. This is what the sketch profile for the revolve should look like. To create this part using the revolve feature, we need to take half of the cross-section and then revolve that around the centre. Take a look at the example drawing below. The first thing to understand is what the sketch profile should look like, in order to create a successful revolve.
