Introduction to Solidworks

01 Software Introduction

SolidWorks (stylized as SOLIDWORKS) is a brand within Dassault Systèmes that develops and markets solid modeling computer-aided design, computer-aided engineering, 3D CAD design an collaboration, analysis, and product data management software.

02 Software Origin

The SolidWorks brand was founded as Winchester Design Systems by Massachusetts Institute of Technology graduate Jon Hirschtick on December 30, 1993. Jon and cofounders Dr. Constantine Dokos, Scott Harris, Bob Zuffante, Mike Payne, and Tommy Li aimed to create 3D design software that was affordable, easy to use, and available on a Windows NT personal computer.
SolidWorks developed the world’s first 3D CAD solution that ran on a desktop PC. They had a simple mission statement of “3D on every engineer’s desktop.
SolidWorks released its first product, SolidWorks 95, on November 1, 1995. Within two months, it established a new benchmark for ease of use. Since then, the 3D CAD product, now known as SolidWorks, has become the flagship product for the SolidWorks brand.
By 2023, approximately 7 million engineers and designers were using SolidWorks software to create production-ready 2D and 3D engineering drawings and advanced 3D models using a parametric feature-based approach. SolidWorks also gives users the ability to perform analyses and simulations, including Finite Element Analysis. The product places an emphasis on faster modeling, new design tools, and enhanced collaboration.

03 Areas of Application

The SolidWorks’s user base ranges from individuals to large corporations and covers a wide cross-section of manufacturing market segments. Its core industries include industrial equipment, high-tech, life sciences, and home and lifestyle, and architecture, engineering, and construction. Commercial sales go through an indirect channel that consists of 500+ partner resellers throughout the world. SolidWorks also partners with third-party developers to add functionality in niche market applications such as circuit layout and tolerance checking.
Directly competitive products to SolidWorks 3D CAD include PTC Creo Elements/Pro, Solid Edge, and Autodesk Inventor.

04 Functional Module

  1. SolidWorks is a 3D CAD software that uses a feature-based approach. It’s equipped with the Parasolid modeling kernel.
  2. Parameters define the shape of a model or assembly and can be numeric or geometric, linked via relations.
  3. Design intent determines how a part responds to changes. For instance, SolidWorks allows users to specify the hole’s position regardless of can size.
  4. Features are the building blocks of parts, either shape-based (using sketches) or operation-based (e.g., fillets, chamfers).
  5. Modeling typically begins with a 2D sketch, where geometry, dimensions, and relations drive design intent.
  6. In assemblies, mates serve the role of sketch relations, aiding in component alignment.
    7.Drawings are created from parts or assemblies, with automated views and easy addition of notes and dimensions. Various paper sizes and standards are supported.

05 Case Studies

The following images roughly show a model of a pet feeder product designed and manufactured using Solidworks.

Comparison of Creo and Solidworks

01 Common

In-memory Parts Management

Creo, Solidworks cannot close files in memory individually.

Edits to Non-Participating Entities

Creo edits non-parametric models through Flexiable modeling. When importing a multi-solid non-reference model, it is slightly more complicated to edit it with Creo.
Solidworks edits the model by directly editing the move/rotate/copy commands, but each step is recorded in the model tree and cannot be de-referenced.

Part Assembly and Movement

Core parts are relatively difficult to move accurately.
Solidworks can only move accurately through the assembly within the assembly.

Multi-Solid Modeling, Welding and Cutting Iists

SW multi-substance modeling, complete the skeleton line design, using a defined sketch section, you can easily scan to generate multi-substance models, and through the welding cutting list to easily generate engineering drawing details. This function SW is the most powerful and convenient.

Shortcut Key

Creo uses mapkey mapping definitions to define two or more combinations of keyboard letters.

Part Templates, Drawing Templates, etc.

SW template settings are more convenient, in the preferences settings, select the path where the modified file is located, you can easily set up, part templates, engineering drawing templates, detail table templates, cutting list templates.
Creo through the file to set the template folder path.

02 3D Modeling

Top Down

Creo uses a skeleton model, copying geometry and publishing geometry to complete top-down modeling, and the main geometric features exist in the skeleton model.
Solidwork top-down modeling, in the parts directly refer to each other, when the reference data is more, and there is a constraint assembly relationship between the parts, the change is more complex, the model is prone to error.

Line Segment Midpoint Selection and Constraints

Creo, SW is unable to select the midpoint of a line segment, and perform midpoint constraints.

Hole Feature Creation

Creo locates holes in both directions and creates groups of holes through arrays.
Solidworks defines hole types and hole positioning through “Simple Hole” and “Shaped Hole Wizard” respectively.

Center Constraints

This assembly constraint is not available in Creo; it is available in Solidworks using the advanced assembly “width”.

03 Engineering Graphics

Drawing Files and 3D Model Files

Solidworks, engineering drawings and 3D model is the same part number, you can realize the virtual background, but the structure of the main model is bloated and complex, large assembly components will reduce the speed of the computer.
Creo, similar to Solidworks, can not insert another part in the drawing file to realize the virtual background.

Weld Marking

Solidwork labeling is easier.
Creo weld labeling is very cumbersome, different types of weld labeling by a different symbol to achieve.
