Fit the knob to the bracket

1. MeasureTools for displaying measurement properties of the edges, faces, and solids in your design. the small cylinder on the end of the knob.

   1. Zoom out of your design by selecting Zoom Out from the Zoom tool menu.

   2. Click Measure in the Inspect group on the Measure tab.

   3. Select the small cylinder.

       

      

       

      You will see measurements including the circle diameter (0.375 in).

      Click on other parts of the model to see their dimensions.

       

2. Change the display and move the bracket so you can see what you're doing.

   1. Right-click Bracket in the Structure treeDisplay in the Structure panel that shows you each of the objects in your design. You can expand or collapse the nodes of the tree to view the objects. You can rename objects, create, modify, replace, and delete objects, as well as work with components. and select Activate ComponentObjectAnything recognizable by the tools. 3D objects include vertices, edges, faces, surfaces, solids, layouts, planes, axes, and origins. 2D objects include points and lines. in a design, including the top-level design component. Each component consists of any number of objects, such as solids and surfaces, and can contain sub-components. You can think of a component as a "part." Components can be saved as a separate file. An external component is another design inserted as a component of your design. Making the component internal prevents changes from being made to the external component file. You can also create an external component by saving a component as a separate file. See Lightweight components, AssemblyHierarchy of components and subcomponents showing relationship within a design, as shown in the Structure tree. In manufacturing, a unit fitted together from manufactured parts. See Assembly tool, Component from the drop-down menu.

      An orange box appears around the Bracket.

   2. RotateDesign: Using the Rotate tool to spin a design 90 degrees in the plane of the screen. You can rotate your design clockwise or counterclockwise. Object: Using the MoveA tool used to translate or rotate geometry. handle to spin an object around an axis. the bracket so you can see its back.

   3. Click the back of the bracket then click Sketch ModeThree ways of designing: Sketch, Cross-section, or 3D. You can switch between modes at any time. in the Mode group. The grid appears on the back of the bracket.

   4. Click the Display tab.

   5. In the GridSee Sketch grid group, select ClipHide all geometry in a design above or below the grid or selected plane. Scene Above Grid. The knob temporarily disappears.

      You may also want to select Fade Scene Under Grid. This will fade the bracket and make it easier to see the sketch profiles you draw.

   6. Return to the Design2D or 3D model that contains at least one top-level component. tab and select Back from the Trimetric tool menu in the Orient ribbon. The back of the bracket now faces you.

3. Create a hole in the back of the bracket so you can insert the knob into it.

   1. Click ConstructionLineA straight line, arc, or spline drawn in Sketch mode or on a layout plane. Lines have length but no area. When you pull a sketch into 3D with the PullTool used to distort or deform geometry. Use the Pull tool to offset, extrude, revolve, sweep, draft, and blend faces; or to round, chamfer, or extrude edges. When converting a sketch to 3D, pulling a line creates a surface and pulling a surface creates a solid. tool, lines become edges. in the Sketch group.

   2. Move the cursor over the top line on the back. The cursor snaps to the center of the line.

       

      

       

   3. Click to start the construction line. Be careful to click on the top of the back and not on the top of the chamfer.

   4. Drag to draw a construction line to the bottom of the surface.

       

      

       

      The line snaps to the center of the bottom edge. Press Esc to exit the tool.

       

   5. Click Circle in the Sketch group and position the mouse at the top of the construction line. (Do not press a mouse button.)

   6. Press and release the Shift key to dimension from another point, then move the mouse slowly in the direction you want to place the circle.

   7. In the dimension box, type the value where you want to locate the circle center (.742). If you need to, press Tab to switch dimension fields.

   8. Press Enter. The cursor is moved to center of the hole.

       

      

       

   9. Move the mouse slowly and a second dimension box appears into which you can type the diameter of the circle (.376). Press Enter. Press Esc to exit the tool.

       

      

       

   10. Click Pull in the Edit group (the view returns to 3-D) and then click on the center of the circle so the direction arrows are over the circle.

       You may need to hide the knob so you can see the bracket. Deselect the check box next to the TutorialKnob component to hide it.

   11. Select the Up To tool guide on the right side of the Design windowArea in the user interface that displays your model or assembly. Also known as Workspace.. Move the mouse to the side of the model and roll the middle button to select the hidden surface. When it is highlighted, click. The circle goes to the surface and becomes a hole.

        

       

        

4. Create an assembly.

   1. Click the check box next to the TutorialKnob component in the Structure tree to make it reappear in the display.

   2. Drag with the middle mouse button to spin the model so the knob is on the right and the bracket is on the left.

   3. Click Select  in the Edit group (or press S), select the surface of the small cylinder on the end of the knob, then hold Ctrl and select the inside surface of the hole.

       

      

       

   4. Click Align in the Assembly group.

      The knob moves so the axis of its end is aligned with the axis of the hole.

   5. Select the flat surface of the knob just behind the small cylinder.

   6. Move the mouse to the side of the bracket, turn the scroll wheel to highlight the back of the bracket. Hold Ctrl and select the back of the bracket.

       

      

       

   7. Click TangentLine that touches a curve (arc or circle) at only one point, without crossing over, and is perpendicular to the radius at the point of tangency. You can sketch a line tangent to a curve or you can sketch an arc tangent to a line or curve. in the Assembly group.

      The knob slips through the hole in the bracket.

       

      

       

      The surfaces that move are those of the model you pick first.
