Approach to Modeling

2D CAD systems and the SolidWorks application have fundamentally different approaches. In 2D CAD systems, you design in a 2D environment. In SolidWorks, you design in a 3D environment, and you create 2D drawings based on the 3D model. The first three lessons of the SolidWorks Tutorials cover basic part, assembly, and drawing concepts.

	2D CAD Systems	SolidWorks

Types of Models	2D drawings	3D solid parts and assemblies, from which you generate 2D drawings
Sketching versus Drawing	drawings	sketching is the basis for features, which are the basis for parts; drawings are generated from part and assembly models
Feature-based Models	models are viewed as a set of lines in 2D	parts are made up of features, as assemblies are made up of parts
Types of files	.dwg files	.sldprt (parts) .sldasm (assemblies) .slddrw (drawings)
Glass Box Visualization	visualize 3D models into 2D drawings	visualize (and convert) 2D drawings into 3D models
Templates	drawing templates	part, assembly, and drawing templates
Dimensions	geometry drives dimensions	dimensions define the geometry
Design Intent	accurate lines describe objects	design intent is captured by dimensions, relations, and equations
Configurations	configurations drawn manually	configurations of part or assembly models created in the model document
Exploded Views	exploded views drawn manually	exploded views are created as configurations in assembly documents
