Content Center Family Editing
We need to change some settings in the Content Center Family just written. Navigate through he Content Center Editor to the new Family. Right Click, and select the Family Table option. The family parameters dialog will appear.
The following are examples that I used, however you will undoubtedly have differences and variations at your company that need to be adopted.
iParts are method of creating Library Contents for similar parts. When you create an iPart, a table is placed in the part, that will contain the individual members of the library. These members are contained in rows of the table, with the key differences edited for each member.
The table contains various fields that represent the parameters that shape the iPart members. The iPart members can have identical values as needed, with the exception of 2 fields. The Part Number and Member name. A lot of care should be taken in planning the Part Number and Member names, as the future file name of library contents is tied to the Member Name, and the Part Number gets fed into the BOM. However, the Content Center Editor can apply variables from the table to concatenate a Part Number automatically, which we WILL do later. For now, we will prepare the table in the following fashion.
Under the Tools Menu, select Create iPart.
The iPart Author dialog will appear, revealing the structure and rows that will appear in the iPart table. Currently there is only 1 row in the iPart table, seen at the bottom of the dialog. This row is fed from the current parameters contained in the part.
The first thing that needs to be completed is kind of the core to this process.
Normally we would begin in an assembly file, but for this exercise we need to go mess around with Autodesk’s artwork. We need to edit the Thread.xls file. You see, the Bolted Connection Generator as well as everything else in Inventor derives it’s threads from this file. This file contains a beautiful collection of thread data, including Inch, Metric, and tapping threads. Unfortunately the facts that bring us here today is that:
a) there is nothing available for ANSI/ASME B18.6.1 Wood screw threads; and
b) The Bolted Connection Generator only reads data from the first 3 thread tables in that file (ANSI Unified, ANSI Metric, ISO Metric).
What we need to do is to add a new row for the B18.6.1 thread for a #6 screw. The new row needs to be added in the ANSI Unified Screw Threads Table. Why? Because if we don’t, the Bolted Connection Generator will not use it. I know this is in bad taste, but it will get the job done. I have no doubt that the table restrictions in the design generator is coded in XML, and that I will eventually find and exploit it. For now, this is the only way.
Navigate to the following VISTA path:
C:\Users\Public\Documents\Autodesk\Inventor 2009\Design Data\Thread.xls.
Open this file with Excel and navigate to the ‘ANSI Unified Screw Threads’ Tab. Select the first #6 thread entry row header, Right click and select Insert. You should see an empty row appear. Add the data from the highlighted row in the table shown below.
Close and save the file. Let’s start the next step by opening a new Inventor assembly.
The Bolted Connection Generator is a fabulous tool. It creates a filter criteria using diameters found in the selected thread type. It then uses that to filter the Content Center selection to create a list of fasteners. The holes and recesses are created from geometry in the separate data. The list of possibilities however, has some limitations. I’d like to show you 1 way to get more productivity, working within the limitations.
If I can get the job done with a Design Accelerator, then why would I want to prep everything without it?
This discussion is a workflow I performed recently to get some new fasteners into the Bolted Connection Generator. Again, the theme has to do with wood, as I found a lot of people asking about wood, and little assistance was available.
This workflow will take us through the following topics:
- Sample Part Modifications
- Content Center Category Review
- Component Authoring
- Content Center Family Editing
- Bolted Connection Generator
- AutoCAD Civil 3D
- Autodesk University
- Design Review
- Bug Report
