Tutorial: Advanced Assemblies Chapter 7

Step 1 – Add Pilot Holes to Hatch Open a sketch on hatch top surface, add points aligned with centers of holes in hinges This step is not required, but otherwise you must be careful when specifying hole locations to specify points associated with the hatch and not the hinge INTRODUCTION TO SOLID MODELING USING SOLIDWORKS 2009

Step 2 - Adding Holes Use Hole Wizard to add 7/64-inch-diameter holes to hatch. Hiding the hinges makes this operation easier INTRODUCTION TO SOLID MODELING USING SOLIDWORKS 2009

Design Intent: Part-Level and Assembly-Level Features Why add holes in assembly rather than to the door part file? Addition of features should reflect manufacturing and assembly process: Are holes drilled in the door using a template before assembly, or Are hinges placed on the door and the holes in the door drilled to match the locations of those in the hinges? Important when creating drawings: in first case, the holes would be detailed on the door part drawing. In the second case, holes would be detailed on assembly drawing.

Step 3 – Create Wood Screw Smart Fasteners Tool examines open holes in an assembly and selects fasteners to fit from the SolidWorks Toolbox , a collection of common components The SolidWorks Toolbox is included with the Education Edition, but not the Student Design Kit Therefore, a simple screw will be created in this tutorial INTRODUCTION TO SOLID MODELING USING SOLIDWORKS 2009

Step 4 – Add Fasteners to Holes Insert one screw into the assembly Choose a coincident mate between conical portions of screw and hole in hinge INTRODUCTION TO SOLID MODELING USING SOLIDWORKS 2009

Step 4 (cont.) Insert a Component Pattern matching the pattern on the holes in the hinge INTRODUCTION TO SOLID MODELING USING SOLIDWORKS 2009

Design Intent: Manufacturing Considerations When deciding whether to add features at the part level or the assembly level, keep in mind that the part may be used in multiple assemblies Hinges could be modeled with no holes, and assembly-level holes added to the hinges and door. However, this would not reflect the actual manufacturing process Model should reflect manufacturing process INTRODUCTION TO SOLID MODELING USING SOLIDWORKS 2009

Step 5: Creating an Exploded View Select components to be exploded in the first step (screws) Drag screws upward, or enter a distance INTRODUCTION TO SOLID MODELING USING SOLIDWORKS 2009

Step 5 (cont.) Select hinges as the next step in the exploded view, drag upward INTRODUCTION TO SOLID MODELING USING SOLIDWORKS 2009

Exploded Views Exploded view definitions are stored as configurations Can be toggled between exploded and collapsed states INTRODUCTION TO SOLID MODELING USING SOLIDWORKS 2009

Step 6 – Add Explode Lines Helpful for complex assemblies to show how parts fit together INTRODUCTION TO SOLID MODELING USING SOLIDWORKS 2009

Interference Detection Interference detection finds and identifies overlapping parts Note that interference will be detected between the screws and holes, since the holes are undersized INTRODUCTION TO SOLID MODELING USING SOLIDWORKS 2009

Collision Detection Can be used with the Move Command to detect contact between components Limits of motion of door: INTRODUCTION TO SOLID MODELING USING SOLIDWORKS 2009
