Use Custom Structural Content to Create Frames
The first section of this Skill Builder explores the steps to add a single size and type of T-Slot structural content to the Content Center library. In the second section, you use the published content to create and modify a 3D frame with Frame Generator.
Estimated Time Required to Complete: 30 minutes
In this Skill Builder, you learn how to:
- Publish 1” x 1” tubing to a read/write library.
- Create a master part file to control the frame size.
- Create a frame with Frame Generator.
- Edit the master part file to change the frame size.
- Have Inventor 2010 with Content Center installed.
- Understand how to create a Project file.
- Understand how to open, create and save part files in your active project.
- Understand the fundamentals of solid modeling.
- Download (and unzip) the zip file containing the source file to use during this exercise to a folder in your active project.
| ||1010_80_20.zip (zip - 187Kb)|
The zip file contains 1010_80_20.ipt, a fully constrained part.
On the Application Options, Sketch tab enable the following settings:
- Edit dimension when created
- Autoproject edges for sketch creation and edit
- Autoproject part origin on sketch create
The Grid lines display is not enabled in any of the sketch environment images in this Skill Builder.
Note: You can specify the icon color scheme in Application Options. The appearance of the icons presented in this Skill Builder will differ if you are not using the color scheme noted in the following image.
To begin, create and activate the required project file.
Click Configure Content Center Libraries in the Projects dialog box (1) and configure the active project to include a read/write library (2).
Open the file 1010_80_20.ipt
Right-click the top part node in the browser and select iProperties.
Click the Physical tab in the iProperties dialog box. Notice that 6061 Aluminum is the assigned material and the part weighs 0.043 lbs.
Note: If the Mass value is not calculated, choose Update to display the value.
Close the iProperties dialog box.
Click the Manage tab.
Scroll to the bottom of the parameter names and note that Length, Width, and Height have been defined as parameters. Click Done to close the parameters dialog box.
Select the drop-down in the Author panel and select the Structural Shape option as shown in the following image. The Structural Shape Authoring dialog box appears.
Specify the Category. Choose Square/Rectangular Tubes on the drop-down menu.
Accept the Predefined Point as the Default Base Point.
Note: If necessary, you can also choose the Select Geometry option to specify an insertion point.
Click the Parameter Mapping tab. In the Template Parameters column, select the button in the Base Length row to open the part parameters. Scroll the Model parameter list and select the Length parameter to assign it to Base Length.
Note: The only required parameter for Frame Generator authoring is the base length.
Select Publish Now when the length parameter value has been assigned.
Click OK in the message box that appears indicating the part has been modified by the publish process.
On the Publish Guide dialog box, select the Read/Write library to publish to (My Library), specify the language (English) and then click Next.
Choose Square/Rectangular Tubes as the Category and then click Next.
Review the mapped Family Columns to Category Parameters. Verify length is assigned. Click Next.
Define Family Key Columns. In this case, Base Length and Part Number are values we want to track. Click to add them to the Key Columns panel.
To match the following image, use the arrows on the right side of the dialog box to make Base Length the first key value and then click Next.
Set the values specified in the following image and then click Next.
Select Publish in the final dialog box.
A message box appears that states Publish completed successfully. Click OK to close the message box.
Create a frame using the published shape
In the next section, we will create a master (skeleton) part file to specify the centerline to centerline dimensions of the frame.
Start a new inch part file.
Create a rectangle centered about 0,0,0.
Add Horizontal and Vertical constraints between the midpoints and the origin as shown in the following image.
The required width of the finished frame is 12 inches in both directions. The default frame generator placement method is about the centerline. For this reason, we will define the master part to be 11 inches square to allow for ½ inch on each side.
Dimension the part 11 inches in each direction as shown in the following image.
Finish the sketch.
On the Model tab, Create panel, choose Extrude.
Select the Surface option on the dialog box. A surface is used because it has no mass or volume and does not affect the frame weight calculation. Set the extrude distance to 35 in to create a 36 inch finished frame size.
Save the part as frame_1.ipt.
Start a new assembly file.
Save the file as frame_1.iam.
Insert the part file frame_1.ipt into the assembly file.
Tip: You can use the Place component command or the drag and drop method to insert the part in the assembly. To drag the part into the assembly:
- Use the Arrange button on the bottom of the screen to tile all open files in a single window.
- Activate the part file window, highlight the top node in the browser, and then drag the part into the assembly window to insert as shown in the following image.
After you place the part in the assembly, maximize the assembly window.
Click the Design tab, and then click Insert Frame in the Frame panel.
In the Insert dialog box, set the following values:
- Standard = ANSI
- Family = 1010_80_20 – 1x1 Tube
- Size = 1010_80_20
- Material Style = Aluminum-6061
Select all edges of the rectangle as shown in the following image.
Click OK to close the Insert dialog box.
Click OK in the Create New Frame dialog box to accept the defaults.
Click OK in the Frame Member Naming dialog box to accept the defaults and create the parts.
Notice that all parts overlap.
The original skeleton surface part is still visible. Right-click the part in the browser and select Visibility to set the part status to not visible.
In the Design tab, Frame panel, start the Trim To Frame command.
For the trim operation:
- Choose the long frame members for the first selection (labeled 1 and colored blue in the following image)
- Choose the short frame members for the second selection (labeled 2 and colored yellow in the following image)
- Click Apply and then repeat the trim operation until all members are trimmed to the intersection.
Tip: A suggested order is to trim the top of the frame first. The bottom of the frame second, and the ends last.
Click OK for the last trim operation or Cancel when all members have been trimmed.
Right-click the top node in the assembly file and click iProperties.
Click the physical tab. Click Update to recalculate the Mass.
Notice the frame weight.
Right-click the surface part file in the browser and choose Open. The surface part file opens in a new window.
Right-click Sketch1 in the browser and choose Edit Sketch.
Change both 11-inch dimensions to 17- inches to create a frame that is 18 inches wide.
Finish the sketch.
Right-click the surface extrusion in the browser and choose Edit Feature.
Change the extrusion distance to 41 in to create a frame that is 42 inches long.
Save the part file.
Return to the assembly file window.
On the top menu, click Local Update.
The frame is modified to the new dimensions.
Save and close the file.
