AutoCAD is an automated computer-aided design software developed by Autodesk that can be used for drafting, 2D drafting, and basic 3D design.
It enables automatic drawing without the need for programming knowledge, making it widely used globally.
AutoCAD can be applied in various fields, including civil construction, decoration, industrial drafting, engineering drafting, electronics, clothing processing, and many others.
Although AutoCAD boasts impressive graphic capabilities, its table processing functions are relatively weak.
In professional work, the need to create various tables in AutoCAD, such as engineering quantity tables, arises frequently. Hence, the question of how to efficiently create tables becomes a practical concern.
AutoCAD has several methods for creating basic graphic objects, such as straight lines, circles, ellipses, polygons, and splines.
AutoCAD provides several drawing aids, including orthogonal lines, object snaps, polar tracking, and object snap tracking.
The orthogonal function allows users to effortlessly draw horizontal and vertical straight lines.
Object snaps assist in selecting specific points on geometric objects, and tracking makes it easier to draw diagonal lines and locate points in varying directions.
Since AutoCAD 2000, the system has introduced many powerful features.
These include the AutoCAD Design Center (ADC), Multi-Document Environment (MDE), internet drive, improved object snap functions, advanced annotation capabilities, and partial open and partial load functions.
Pro/Engineer is an integrated 3D CAD/CAM/CAE software developed by PTC, a US-based company.
It is well-known for its parametric capabilities and was one of the first software to introduce parametric technology. Pro/Engineer holds a significant position in the current 3D modeling software landscape.
Today, Pro/Engineer is widely acknowledged and promoted in the industry as a new standard in the field of mechanical CAD/CAE/CAM. It is considered one of the leading CAD/CAM/CAE software, particularly in the field of product design in China.

This single database ensures that all project materials come from the same source, allowing each user, regardless of department, to work on the same product model.
As a result, changes made in any stage of the design process are reflected throughout the entire design process, providing greater efficiency and consistency.
In the Pro/Engineer software version, in addition to using major versions like proe2001, Wildfire, WildFire2.0, WildFire3.0, WildFire4.0, and WildFire5.0, there are also minor version differences in date codes within each major version.
These different date codes represent the order of the release date of the major version.
SolidWorks is a 3D design software originally built on the Windows system.
With its user-friendly interface and ease of use, SolidWorks can automatically capture design intent and guide design changes throughout the entire product design process.

Regardless of whether the design process uses a “top-down” or “bottom-up” approach, SolidWorks operations make it easier to improve design efficiency.
Users are not only using SolidWorks software to address general part design issues but are also increasingly turning to it to tackle large-scale assembly designs at a system-level.
Due to the growing demand from users, the R&D department of SolidWorks has significantly improved the upload speed of large assemblies through various means, such as distributed data processing and the implementation of graphics compression technology.
