What is AutoCAD Software?
The AutoCAD software is an application that allows you to draw 2D drawings as well as 3D model prototypes of your projects. This software was invented by Autodesk in 1982, and it was one of the first computer aided design software programs that was available for personal computers.
It is a part of the Application Integration domain. Before AutoCAD software, professionals had to draw everything by hand using drafting tables and instruments. This solution made design work faster, more accurate, and easier to modify.
Real World Example of AutoCAD Software
Let us consider an example of a construction site. The project was delayed because the architect’s hand-drawn design plan had many measurement errors, which were discovered only after the foundation was laid.
In this situation, you could use AutoCAD, which has precision tools that could identify these errors before the foundations are laid. This way, you could have saved rework costs and completed the project ahead. This is one of the ways you could use this software.
This is one of the examples of what AutoCAD is used for. In the next section below, we have listed some more uses of this tool in various industries.
Features of AutoCAD Software
AutoCAD software provides various features like 2D drawing, 3D modelling, collaboration features, and much more. Look at each of these features and their various sub-features used by the professionals in brief.
AutoCAD provides many tools for creating 2D drawings. The drafting tools include snap functions that help align objects perfectly and maintain accuracy throughout the drawing process. Some of the other tools include:
- Text Tools: These tools add dimensions, notes, and labels to drawings, and ensure consistent formatting and styles.
- Measurement Tools: These are used to calculate distances and angles automatically with their built-in measurement functions.
- Geometric Shapes: This is a straightforward tool that draws lines, circles, rectangles, polygons, and complex curves using mathematical functions and equations.
2. 3D Modeling and Visual Rendering
The software also includes advanced 3D capabilities that may be used for creating realistic models and prototypes:
- 3D Modeling Tools: You can build solid objects, surfaces, and mesh models using commands like extrude, revolve, and sweep.
- Visual Rendering: You can apply materials, lighting, and camera angles to create photorealistic images of 3D models and also imagine what they will look like once they are complete.
- Walkthrough Animations: This is an advanced feature where you create animated presentations that show viewers moving through architectural spaces.
3. Automation Features
AutoCAD Software has several automation tools that automate repetitive tasks and save you a lot of time:
- Macros: You can record a sequence of commands and replay them with a single click. This is what automating the common operations means.
- Scripts: You can write custom commands using AutoLISP programming language for specialized functions specific to your products.
- Shortcuts: You can also create keyboard shortcuts and custom toolbars to access frequently used commands quickly.
4. Collaboration and Cloud Connectivity
Modern versions of this tool support team collaboration through cloud-based features:
- File Sharing: Share drawings through Autodesk’s cloud storage system for real-time collaboration.
- Version Control: Track changes and maintain drawing history to prevent conflicts between team members.
- Mobile Access: View and mark up drawings on tablets and smartphones while away from the office.
5. Additional Professional Features
Some other specialized features that are used by professionals across various industries are:
- Layer Management: This tool helps you organize drawing elements on separate layers for better control and visibility options. For example, when drawing a house plan, you can put walls on the “WALLS” layer, the electrical outlets on the “ELECTRICAL” layer, and so on. When you want to focus on a single layer, say WALLS, for example, you could turn off all the other layers, and they will become transparent.
- Blocks: You can also create reusable drawing components like symbols, details, and standard parts. For example, create a door symbol once as a block, then insert it anywhere in your drawing. If you need to change all doors from 800mm to 900mm wide, you just edit the block once, and every door in your drawing updates automatically.
- Parametric Constraints: You can explicitly define the relationships between objects so they update automatically when designs change. For example, you can draw a window and set a constraint that it must always be centered on a wall.
- Templates: When starting a new project, you can apply pre-configured settings, layers, and title blocks with just one click.
- Export Options: Save drawings in multiple file formats for compatibility with other software and printing requirements. Save your drawing as a PDF to email to clients, export as a JPEG image for presentations, or save as a DXF file to open in other CAD software that your contractor uses.
