Those documents can be a variety of things including parts and other assemblies. Inserting Documents All of the assemblies created in this first section will not need to have constraints added to properly position them. The first assembly that will be built is a basic hand drill. This drill is made of the following parts. The caption under each picture is the filename so the parts can be referenced to as needed. Case 1 Handle Arm Handle Knob Drive Gear CATIA Assembly Design CATIA® V5R14 Assembly Design - Inserting documents, Page 12 ©Wichita State University Output Gear Drill Chuck 1 Drill Bit 1 Start a new product document. This can be accomplished by selecting the new icon and selecting product. You need to make sure you are in the assembly design workbench before continuing. To switch to the assembly design workbench select the change workbench icon and then select assembly design. One of the most important ideas to keep in mind with assembly design is that all parts must have an unique id. The assembly should also have an unique id, especially if it is going to be used as a sub-assembly. Using the third mouse button select Product1. This will bring up the contextual menu for Product1. Select Properties andthentheProduct Tab. This is where various information about the assembly, as well as individual parts can be stored. Filling in all of the information is not necessary, but can become quite useful to a down stream user. For now, the Part Number is the only field that will be changed, but feel free to fill in any of the other fields. CATIA Assembly Design CATIA® V5R14 Assembly Design - Inserting documents, Page 13 © Wichita State University Change the Part Number to Hand Drill. Select OK when done. This will give the assembly an unique id, so that in case this was to be used in a larger assembly, say a garage mock-up, then there would be no conflicts. Select the existing component icon. The icon will highlight and is waiting for the user to select a product to insert the component into. Select Hand Drill. This will define what product the component will be placed into. A File Selection window appears. Double select the Assembly Basics directory and select Case 1. Select Open. The first case is now inserted into the hand drill product. The other components will be inserted to complete the assembly. Select the existing component icon, and select Hand Drill. The File Selection window will automatically open to the Assembly Basics directory. Select Drive Gear, and select Open. The drive gear is inserted into the assembly, pre- positioned. If so desired, the case can be hidden to reveal the drive gear better. Be sure to have all parts shown before continuing. Notice some of the components can be made into a sub-assembly. For example, the output gear and drill chuck can be combined together. This can either be done before hand, as with the handle assembly that you are going to insert later, or the sub-assemblies can be generated on-the-fly as you will do next. Select the product icon and select Hand Drill. This will insert a new product into the assembly. A Part Number window appears. CATIA Assembly Design CATIA® V5R14 Assembly Design - Inserting documents, Page 14 ©Wichita State University A part number must be assigned to the new product. Part numbers can either be generated by the computer or generated on-the-fly. The option to change how new product part numbers are generated is under Tools, Options, Infrastructure, Product Structure, Product Structure tab,andPart Number Manual Input. Your system is set up for manual input of the part number. To insure your ability to distinguish between the different products, you will name this one Output Assembly. Key Output Assembly in the Part Number window and select OK. This will change the instance name, allowing for better model management. Now that you have a nested product assembly, a product within a product, you need to make sure that you insert new and existing components into the proper product. Select the existing component icon and select Output Assembly. Again, the File Selection window displays. This time you will insert multiple components at the same time. Select Output Gear, hold down Ctrl on the keyboard, and select Drill Chuck 1,then select Open. This will insert both documents into the Output Assembly product. You can expand the Output Assembly product to reveal this by selecting on the plus sign next to it. The handle assembly is already put together as a separate product. You will insert this next. Insert an existing component into Hand Drill. The File Selection window will show again. Select Handle Assembly and then Open. This inserts the Handle Assembly into the Hand Drill assembly. You can expand this sub-assembly by selecting the plus sign next to it. Insert Drill Bit 1 into the Hand Drill assembly. This completes the Hand Drill assembly. The specification tree should appear similar to the diagram shown below. You will probably have to expand some of the branches. [...]...
