Engineering Design with SOLIDWORKS® 2018 Fundamentals of Assembly Modeling

An assembly combines two or more parts. In an assembly, parts are referred to as

components. Design constraints directly influence the assembly design process. Other

considerations indirectly affect the assembly design, namely cost, manufacturability and

serviceability.

Project Overview

Translate the rough conceptual sketch into a

SOLIDWORKS assembly.

The GUIDE-ROD is the first assembly.

Determine the first component of the assembly.

The first component is the GUIDE. The GUIDE remains

stationary. The GUIDE is a fixed component.

The action of assembling components in SOLIDWORKS is

defined as mates.

Mates are relationships between components that simulate

the construction of the assembly in a manufacturing

environment. Mates affect/restrict the six degrees of

freedom in an assembly.

The CUSTOMER assembly combines the GUIDE-

CYLINDER assembly with the GUIDE-ROD assembly.

Assembly Modeling Approach

In SOLIDWORKS, components and their assemblies are

directly related through a common file structure. Changes

in the components directly affect the assembly and vice

versa. Create assemblies using the Bottom-up assembly

approach, Top-down assembly approach or a combination

of both methods. This project focuses on the Bottom-up

assembly approach.

The Bottom-up approach is the traditional method that combines individual components.

Based on design criteria, the components are developed independently. The three major

steps in a Bottom-up assembly approach are Create each component independent of any

other component in the assembly, insert the components into the assembly, and mate the

components in the assembly as they relate to the physical constraints of your design.
