1 Laboratory Demonstration Exercises 3-1

2 Lab Demo 1 - Plus Block Open SolidWorks, click on new document part OK. Right Click on Front Plane, click on Sketch icon (pencil w/ axes). In the sketch toolbar on the top, click on the Rectangle icon. Starting in quadrant 2, Click and Drag a rectangle across the origin ending in quadrant 4. Escape when done. Click on the Dimension icon (right above the sketch icon). Click on the right vertical line, draw the mouse to the right and set the length to 1 inch. Click on the bottom horizontal line, draw the mouse down and set the length to 4.5 inches. Click on the bottom line, click on the origin, drag right and set the distance to.5 inch. Click on the left line, then click on the origin, pull down, set dimension to 2.25 inches. The rectangle is now all black which means that it is fully defined fully dimensioned and locked to the origin. The base feature must always be tied to the origin in some way in order to become fully defined. To create a solid from this sketch click on the feature tab just above the Feature Manager. Select the Extrude Base icon in the upper left. The view will rotate to an isometric view. In the pull down menu change blind to Mid Plane and set the length to 4.0 inches. Pressing Enter will give you a preview of the extrusion. Click on the check mark when it is OK. In the Feature Manager there is now an item called Base-Extrude1. this should already be selected and ready to be edited. Change the part name to Plus-Block Base. Check Point 1. File: Save as LabDemo1 Right click on the top face of the block to select this as the next plane to sketch on and click on the sketch tool icon in the fly out menu. At the top of the work space are quick select icons in the transparent Heads-Up toolbar. Pick the top view. Pick the line tool in the Sketch Tool Bar. Starting about 1/3 of the way in from the right on the upper edge of the 3-2 block, click and draw a line about 1.5 inches long to the left. Now draw a line straight down to the bottom edge, draw a line 1.5 inches to the right along the bottom edge until you are just under the starting point and finally close the figure. Activate the smart dimension tool. Click on the right edge of the block and then click on the right vertical line you just drew. Draw the cursor up and set the dimension to 1.5 inches. The line will turn from blue to black. Do the same from the left edge to the left line. To add to the solid base block click on the Feature tab and select the Extrude Boss icon. Then click on isometric view. Leave the extrusion blind and set the length to 2.0 inches. Press Enter for a preview and reverse the direction if necessary. Click on the check mark when it is OK. In the Feature Manager there is now an item called Base-Extrude2. Change the part name to Plus-Upright. Repeat the above steps but on the bottom. Select the bottom view from the pull down selection at the top of the work space, right click on the bottom face and then click on thesketch icon. With the line tool, draw and dimension the rectangle as above and extrude it down 2 inches. Rename this feature as Plus-Bottom. We now have a solid plus shaped block in isometric view. If you don t have this figure, you may open the check point #2 file retrieved from the server and catch up with the demonstration. Check Point 2. Save File To drill the holes, start by right clicking on the top face of the block followed by a click on the Sketch icon. In the view toolbar, click on top view. Click on the circle drawing tool, click on the origin and drag a circle of about.5 inches in radius. Click on the dimension icon, click on the circle and set its diameter to 1.0 inch. The circle should be black meaning it is completely defined.

3 Select the feature tab and click on the Extruded Cut icon. Change Blind to Through All and click OK (check mark). Change the name from Cut-Extrude 1 to Circular Hole. Click on isometric view in the view toolbar to see the hole. Right click on the front face, click on sketch icon and change the view to front. Click on the rectangle drawing tool. Click in Quadrant 2 in the center part of the plus, drag down to Quadrant 4 and click to set the rectangle. Set the dimension of the rectangle to.5 high by 1.0 wide. Draw a centerline diagonally through the rectangle. Esc: click on the line and control click origin. Select midpoint (the whole rectangle becomes black.) As with the circle, do an extruded cut through the body. Change the name from Cut-Extrude 2 to Rectangular Hole. Return to Isometric view. Check Point 3. Save File Right click on the right face, sketch and right view. Draw a horizontal line about 1.5 inches long above the origin, right click, select tangent arc, click on the end of the line just drawn and draw a half circle to the right and then downwards and back to just under the starting point of the arc, right click to line, draw a line of equal length to the one above, right click to tangent arc and draw an arc left - upward right to close the slot sketch. Make the lines 1.5 inches long, the circles.25 inches in radius. Draw a centerline between the two centers. Esc: Click on the line and control click origin. Select midpoint. The slot is completely defined. Select Feature tab then Extruded Cut and do a blind cut 2.75 inches deep. Pick OK. Change the name from Cut- Extrude 3 to Slot. Change to isometric view.check Point 4.

This is a four bar linkage which will be analyzed in depth in Dynamics and Intermediate Dynamics. Pins could be added to make the system more realistic, but the motion would not be affected. Before bringing the assembly into a drawing make sure the order of parts in the feature manager is how you want them in the BOM. Drag the icons up and down until they are in the order FourBar2 (Crank), FourBar3 (Rocker Arm, FourBar4 (Connecter) and FourBar1 (Base). Drag the components in the Feature Manager into the correct order. Now bring the assembly into a Landscape drawing as an isometric view. Leave the scale at 1:4.
