Parametric Modeling II Project #7

Objective: The student will create part model of an Arbor Weight using dimension variables linked to a spreadsheet to control parametric parameters.

Assignment:

Part 1: Arbor Weight Inventor model: Construct the model of the Arbor Weight. Reverse engineer the Arbor Weight by taking measurements for the existing object. Create a sketch showing the necessary views and the dimensions.

Add the following iProperties for all parts and drawings: Summary tab Author: (your name) Project tab Part number: (ARBOR WEIGHT) Description: (ARBOR WEIGHT) Project: (PROJECT 7) Designer: (your name) Engineer: (your name) Physical tab Material: Cast Steel

Part 2: Excel Spreadsheet: Create an Excel spreadsheet to change the thickness dimension (Height) of the Arbor Weight by varying the Weight value. Use the formula (Volume x Density = Weight). Volume is calculated as (length x width x height).

Open Microsoft Excel and create a new spreadsheet.

Create a cell in column (A) and enter the data items in a row in the following order: parameter name, value or equation, unit of measurement, and comment. The parameter name and value are required; the other items are optional.

You can include row headings or other information in the spreadsheet but they must be outside the block of cells that contains the parameter definitions.

Create the following cells: Length, Width, Height, Weight, and Density. Input data in the Length, Width, Weight, and Density cells. The Density is (0.2836 lbs/in^3) for the material Cast Steel and the starting Weight is 25lbs. The Height cell will contain the formula to calculate the height dimension based on the input data in the other cells.

When calculating the volume, be sure to subtract the slots.

Save the spreadsheet.

Part 3: Link the Excel spreadsheet to the Inventor model: Link the Excel spreadsheet to the parametric model. The extruded thickness of the parametric model should change by entering different values for Weight in the spreadsheet.

To link or embed the parameters spreadsheet, open the model file in Autodesk Inventor.

In the Manage tab select the (fx) Parameters.

In the (fx) parameters dialog box click the Link button to find and select the spreadsheet.

In the Open dialog box, specify the starting cell for the parameter data in the spreadsheet. Locate the Model Parameter variable for the height dimension and replace the equation variable with the linked variable from the Excel spreadsheet.

To test the link, change the Weight value in the Excel spreadsheet and save the file. Select the Update button to update the Inventor model.

Part 4: Add a decal to the Inventor part model: Add the CCAC decal to the face of the Arbor Weight model.

In the 3d model tab, click the start 2d Sketch tool, and select the face to place the decal.

In the Sketch tab, click the Insert Image tool. Browse to locate the image file, and then click OK.

In the graphics window, click to place the image, and then right-click and click OK.

Use dimension constraints to position the image, and then right-click and select OK. Right-click again and select Finish Sketch.

In the 3d model tab, click the Decal tool. Click the image to select the decal image. Click Face and select the face on which to apply the decal. Clear the check box to project the decal image instead of wrapping. When the decal is applied, click OK.

Part 5: Inventor Drawing Complete a fully detailed annotated drawing of the Arbor Weight using the template file for size “C” sheet layout.

Create three orthographic views including a top view, a front view, and a right side view. Display the views showing all hidden lines. Add all centerlines for circles and arcs. Add all dimensions.
