What is CAD?

Building construction design professionals, architects, engineers, and construction managers utilize CAD to create detailed and accurate designs. CAD designs encompass precise illustrations or plans for new buildings and can be represented in either 2D or 3D formats. The specific capabilities of CAD software vary, with some programs offering exclusively 2D or 3D design, while others provide both options.

CAD offers essential features like detecting design flaws, ensuring accurate measurements, and performing advanced design analysis. CAD software uses X, Y, and Z coordinates representing horizontal, vertical, and depth dimensions to create 2D or 3D models based on project needs.

Also called CADD, CAD is a tool for architects, engineers, and other professionals to design and draft buildings. CAD technology originated in the 1960s, enabling designers to create computerized drawings, while the 1970s saw manufacturers increasingly adopting CAD for design and interaction. Nowadays, CAD, although well-established, continues to evolve and play a crucial role in modern design and construction across various industries.

Is CAD 3D or 2D? 

CAD, commonly perceived as solely a 3D modeling instrument, offers much more versatility than many realize—it also functions as a platform for 2D drawing. Construction drawing experts, including those providing freelance 2D-to-3D conversion services, can utilize a CAD tool dedicated to 2D drafting. Additionally, architects can work with a 3D design tool equipped with 2D conversion capabilities.

The choice of tool largely depends on the specific CAD platform employed. The advantage of using an exclusive 2D design tool lies in its cost-effectiveness, as companies pay solely for the design tool they use. However, with the contemporary construction landscape increasingly emphasizing information-rich models and 3D representations, relying only on a 2D design tool may pose challenges for companies.

Freelance 2D-to-3D conversion services are crucial in bridging this gap by providing the necessary expertise to convert 2D drawings into detailed 3D models, ensuring that companies stay aligned with modern construction trends and reap the benefits of both 2D and 3D modeling.

Different types of CAD in construction

The construction industry uses two different types of CAD software:

1. 3D or 2D CAD for technical drafting and drawings 

Technical drawings created with 3D or 2D CAD software provide detailed information about an object’s composition, dimensions, shape, and insights into its fabrication process. There are two distinct types of drawings in this context. The first drawing, a sketch, is created freehand without drafting instruments and is a preliminary representation of the design concept.

The second or final drawing is produced precisely and guided by specific instructions. Final drawings are often created using CAD software to ensure accuracy and adherence to design standards, and they serve as the authoritative reference for the object’s construction or manufacturing.

Technical drawings also have several different types, such as:

  • 3D drawings (perspective, isometric)
  • Complete working drawings
  • Exploded-view 3D drawings
  • Detail drawings (2D orthogonal projections)

After the design is ready, drafters will use CAD software to create 2D drawings and floor plan design services, landscape design services, building inspection plans, and building permit drawings. 

CAD software for drafting can also come in handy for faster and more precise drafting of designs without using technical drawing instruments and stencils. It lets users annotate and document drawings with tables, leaders, dimensions, and text. 

3D or 2D technical allows technical drafters to make the necessary revisions if errors occur. It is more reliable, unlike manual drawings, where drafters will be required to draw everything again from scratch. 

2. CAD solid modeling

CAD solid modeling is among the most common practices that different vendors use for outsourcing due to the increasing costs of construction and developing complex structures. This software also uses new-age tools to optimize, analyze, create, and modify object models or to develop special effects and animation of projects and buildings. Some of its functions are the following:

  • A comprehensive view of proposed buildings from various angles with featured elements, shapes, and colors. 
  • Schedule quantity calculation and generation of a project.
  • Reviewing the design elements before the start of the actual process of construction. 

There are three types of CAD solid modeling, and these are 3D CAD for solid modeling, 3D CAD for surface modeling, and 3D CAD for wireframe.
