Autodesk Inventor Advanced Module 3 Hole Features

Transcription

1 Inventor Self-paced ecourse Autodesk Inventor Advanced Module 3 Hole Features Learning Outcomes When you have completed this module, you will be able to: 1 Describe center points and drilled, counterbored, countersunk and threaded. parametric hole features. 2 Describe and apply the CENTER POINT and HOLES commands to locate and create drilled, counterbored, countersunk and threaded parametric hole features in a part. Hole Features A hole feature is a parametric drilled, counterbored, countersunk or threaded hole. See Figure 3-1 and 3-2. The hole feature is created with the HOLE command and assigned properties such as diameter, depth, thread type and termination methods. Once a hole feature has been created in the part, it can be copied or arrayed in rectangular or circular pattern. The copied or arrayed holes only represent the original feature and if it is revised, all the holes that were copied or arrayed from it will automatically update. Figure 3-1 Hole Features Holes are created and located onto the sketch either in a specified location or onto a center point inserted and constrained on the sketch. You specify the hole on a preview image in the Hole dialogue box. Center Points The CENTER POINT command is used to create center points on a model. Center points locate the center of hole(s) that are automatically found by the HOLE command. Figure 3-2 Hole Features - Section View Hole Features The CAD Guys Ltd. Copyright Module 3

3 Inventor Self-paced ecourse - Autodesk Inventor Advanced - Revised Inventor Command: CENTER POINT The CENTER POINT command is used to create a center point on a part. The HOLE command automatically finds the center point(s). Shortcut: None When inserting a hole(s) on the part, use the HOLE command to do it rather then creating the holes using geometry as you have been doing up this point in the modules. They are easier to create and edit in the future. Inventor Command: HOLE The HOLE command is used to create parametric drilled, counterbored, countersunk, or threaded holes in a part. The depth of the holes can be specified. Shortcut: H Hole Features The CAD Guys Ltd. Copyright Module 3

Start a new part using the template: English-Modules Part (In).ipt. Step 2 Save and name the part: Inventor Advanced Workalong (Figure Step 2) Step 3 Draw the Base sketch on the Top view (XY plane). Figure Step 2 Dimensioned Multiview Drawing Step 4 Project the Center Point onto the Base plane. Step 5 Using the multiview drawing shown above, create the base solid. Note the location of X0Y0Z0.

5 Inventor Self-paced ecourse - Autodesk Inventor Advanced - Revised Step 6 Start a new sketch on the top plane. Enter the CENTER POINT command and place a center approximately in the center of the model. (Figure Step 6A and 6B) Figure Step 6A Figure Step 6B Author's Comments: To speed up the modeling process, the location of the center point can be approximated and then located exactly with dimensions. Step 7 Place two dimensions from the edges to the center point to constrain it onto the sketch. Finish the sketch. (Figure Step 7) Figure Step 7 Hole Features The CAD Guys Ltd. Copyright Module 3

6 3-6 Inventor Self-paced ecourse - Autodesk Inventor Advanced - Revised Step 8 Enter the HOLE command. Set the counterbore hole. (Figure Step 8) Figure Step 8 Author's Comments: The HOLE command will automatically find the center point in the current or unconsumed sketch. Step 9 Start a new sketch on the right side of the model. Enter the CENTER POINT command and place a center point by snapping it to the center of the arc. Ensure that you snap to the center of the arc so the center point is constrained. It will not require any dimensions.

7 Inventor Self-paced ecourse - Autodesk Inventor Advanced - Revised Step 10 Finish the sketch and enter the HOLE command. In the Hole dialogue box, fill it in as shown in the figure. (Figure Step 10) Figure Step 10 Author's Comments When you set the hole termination to Through All as you did in Step 10, see figure right, it will go completely through the model even if there is a space between as it is in this model. Note how both holes were created. Step 11 Using the ORBIT command, orbit the model so that you are looking at the bottom as shown the figure.

The Key Principles in Module 3 1 When inserting holes on the part, use the HOLE command to do it rather then creating the holes using geometry as you have been doing up this point in the modules. They are easier to create and edit. 2 Insert center points to locate the center of holes rather then using geometry to locate the centers. This method is much faster and easier. 3 To speed up the modeling process, the location of the center point can be approximated and then located exactly with dimensions.

14 Inventor Self-paced ecourse Autodesk Inventor Module 13 Loft Features Advanced Learning Outcomes When you have completed this module, you will be able to: 1 Describe a loft. 2 Apply the LOFT command to blend or transition a solid that connects two or more planer sections or part faces of different shapes. Loft Features A loft feature, created with the LOFT command, is a blend or transition solid that connects two or more planer sections or part faces that usually have different shapes. The planer sections also called profiles. For example, you can create a solid that connects a circular and a rectangular shape as shown in Figure The LOFT command can create complex shapes like the ones used in commercial products. A good example of this would be a cellular phone. In this module, you will be learning how to create simple lofts. There is no limit to the number of sections that can be lofted in a single command.
