How does surface sweep differ from surface extrude in CAD?
Question
How does surface sweep differ from surface extrude in CAD?
Solution
In CAD (Computer-Aided Design), both Surface Sweep and Surface Extrude are used to create 3D objects, but they do so in different ways.
-
Surface Extrude: This is a straightforward method of creating a 3D object. It involves taking a 2D sketch or profile and extending it in a straight line along a specified path, or 'extruding' it. This path is usually perpendicular to the plane of the sketch. The result is a 3D object that has the same cross-section along its entire length. For example, if you extrude a circle, you will get a cylinder.
-
Surface Sweep: This is a more complex method of creating a 3D object. It also involves taking a 2D sketch or profile, but instead of extruding it in a straight line, it is 'swept' along a specified path. This path can be curved or straight, and it doesn't have to be perpendicular to the plane of the sketch. The result is a 3D object that can have a varying cross-section along its length. For example, if you sweep a circle along a spiral path, you will get a helix.
In summary, the main difference between Surface Sweep and Surface Extrude in CAD is the path along which the 2D sketch is extended to create the 3D object. Extrude uses a straight path, usually perpendicular to the sketch, while Sweep can use any path, straight or curved.

Read the text and answer the following questions with NO MORE THAN THREE WORDS AND/OR NUMBERS.Types of CAD SoftwareCAD or Computer Aided Design software was introduced in the late 1960's to expedite engineering drawing process. There are various flavors of CAD available today and there are different methods of classifying them. In this text, we divide CAD software into two main types:2 Dimensional CAD (2D CAD)2D CAD is the pioneer of CAD software, and was developed in the early 70s. At that time, major automobile, aerospace and other engineering companies developed in-house tools to automate repetitive drafting requirements. 2D CAD relies on basic geometric shapes like lines, rectangles, circles, etc. to produce flat drawings. These types of softwares have been first developed way back in 1970’s.3 Dimensional CAD (3D CAD)3D CAD is a step up from the 2D CAD software of yesteryears. As the processing power of computers increased and the graphic display capabilities improved, 3D CAD has become an increasingly popular design tool. 3D CAD allows creation of 3D images that are realistic. These images are called 3D models as they can be viewed and rotated in any direction – X, Y or Z. You can also display views from a 3D model, such as isometrics or perspectives, from any angle using 3D CAD. 3D CAD tools were introduced in 1980’s by a partnership between IBM-Dassults. 3D CAD quickly became popular because of enhanced visual capability.The rapid advancement of 3D software today has helped quick turnaround in product design, giving birth to the concept for product lifecycle management (PLM). A few of today’s leading 3D CAD software includes SolidEdge and SolidWorks. Of course, with the vast array of tools, professional training is needed to master these tools.When was CAD first used in engineering drawing process?
