History & Definition:

Launched in 1982, AutoCAD is basically a software which helps in designing accurately and efficiently. From simple floor plans to complex mechanical systems, the tools help visualize and draft for anything. Since its continuous evolution, the present version supports cloud collaboration, mobile access, automation tools, and even specialized toolsets particularly for architecture, mechanical engineering, and electrical design industry.

Uses:

• It’s versatile in nature.
• Build and architect plans
• Engineer schematics
• Product and machine design
• Civil and infrastructure projects
• Urban planning and GIS mapping

If it needs to be visualized or built, AutoCAD probably has played a role in designing it.

AutoCAD: Functions

• AutoCAD acts as a digital drafting paper where you can simply design 2D or 3D visuals with no need to waste paper on framing models.
• Draw basic shapes and turn them into complex designs. It offers its users to make complex designs with help of even a simple basic shape.
• Turn 2D to 3D views and vice versa. It also gives an option to convert 2D into 3D visuals which helps users understand their design after framing it in 2D or vice versa.
• It gives a feature to add layers, dimensions, annotations, and more.
• Use scripts or macros to automate repetitive tasks. Repetitive tasks take a lot of time, AutoCAD comes with the feature of easing the task through the use of scripts and macros.
• Files can be saved in DWG format, widely accepted across the industry. DWG format helps easy access and import/export of files to other softwares and tools.
• It acts as an on the go tool. Its availability as an App allows a team to work seamlessly irrespective of their location.

Hidden Gems in AutoCAD You Should Know:

While AutoCAD is widely known, several advanced features and tools are often neglected. These are the hidden gems which boost productivity and kick your designs efficiently. Below are some unique and lesser known functionalities of AutoCAD.

1. Plug-ins and Extensions:

A wide range of third-party plug-ins are available through the Autodesk App Store supported by AutoCAD. These extend core functions of software due to which specific tasks like staircase generation, topography modeling, or importing/exporting Google Earth terrain can be performed. Tools like “Spiral Stairs” or “CAD-Earth” can significantly streamline your work if it’s for architecture and civil engineering. These tools also makes your work more customized and faster.

2. Parametric Designing:

AutoCAD enables dynamic relationships with elements by applying geometric and dimensional rules to objects. This feature allows you to apply changes to only one part but that change is reflected across the entire model (especially useful in mechanical and product design). It brings consistency and logic while minimizing the manual updates.

3. Built-in Rendering and Visual Styles:

AutoCAD provides real-time rendering tools and visual styles enabling its users to create instant presentation drawings. You can apply materials, lighting, shadows, and even background settings directly in the workspace. These visual tools help stakeholders visualize the design without leaving the platform or exporting.

4. Point Cloud Integration:

AutoCAD also supports the integration of real world environments 3D scans point clouds obtained from LiDAR or drones which allows you to work with real-site conditions, ideal for renovation projects, historical documentation, and infrastructure maintenance. Through this feature, users can create accurate models over existing terrain.

5. Geolocation and GPS-Enabled Drawings:

Place your drawings on real-world coordinates using live map data such as Bing Maps. This is helpful in civil, landscape, and urban planning projects requiring location specific accuracy. It also allows importing topographic data to align the designs precisely with actual geography.

6. XRefers & Data Shortcuts:

External references (Xrefs) includes attaching external files as we all know but on other hand it also provides data shortcuts, especially in Civil 3D allowing a deeper data sharing and object-level referencing between projects. Using these features improves collaboration in multi-disciplinary projects.
