5 Main Differences Between 2D CAD And 3D CAD Modeling For CAD Architectural Design Services in 2023

By making the design-drafting process quicker, more effective, and largely error-free, seasoned CAD architectural design services providers have transformed the functioning of the building trade through new-age Architectural Drafting Services. The previous manual paper-and-ink procedure, which was utilized for centuries, was arduous, time-consuming, and inaccurate. CAD architectural design services assist architects in producing ideas more imaginative and useful. Once more, they make it possible for building experts to manage challenging projects involving numerous floors in a unique and effective way.5 Main Differences Between 2D CAD And 3D CAD Modeling For CAD Architectural Design Services in 2023

One might wonder what the extent of CAD design and drafting services would be, considering how, in recent time, the advent of BIM modeling services has transformed the AEC industry. But CAD drafting still has many applications and offerings, such as –

  • Paper, PDF, Point-Cloud Scans to CAD Conversion Services
  • Architectural 2D Drafting Services for all project phases
  • Redline Markup & PDF to CAD Drafting
  • Sanitation, Storm Water & Sewerage Drawings
  • Permit Drawings
  • Construction Document Sets

Advantages of architectural CAD design services: Following are some main advantages of CAD design and drafting process over the earlier manual architectural drafting.

  • The procedure becomes a lot quicker and more precise.
  • Since every adjustment is reflected across all drawings, the associated elements feature makes sure that the process of changes and alterations becomes considerably faster.
  • You are quick and effective at prototyping and repeated work.
  • With the use of CAD architectural design services, you can quickly identify mistakes and clashing features.
  • Complex multi-floor projects become simpler and more precise to work on.
  • Specs and other materials can be displayed well.
  • A strong client interface makes it feasible to accurately communicate design purposes to clients.

Significance of 2D CAD drafting and 3D CAD modeling:

In essence, 2D CAD drafting is a manual extension of 2-dimensional drawing. Technical drawings and marked-up designs are produced using it. Building floor designs and facility layouts fall within this category. It is possible to produce accurate drawings without tools or stencils. 

Using 2D CAD, you can still conceptualize in two dimensions. The next stage of this growth is 3D CAD modeling, which enables architectural CAD design services to envisage the design and work in three dimensions right away. In this way, the process of creating 2D drawings incorporates 3D rendering. 

Three types of 3D CAD modeling are:

  • Wireframe modeling: a simple drawing of the planned structure, similar to 2D projections
  • Surface modeling: Wireframes are expanded with surfaces. Exteriors hold more weight. No specifications about the interiors are given in these models
  • Solid 3D modeling: Most complete 3D model. A complete idea of the structure, both interiors, and exteriors.  

Differences between 2D and 3D CAD: When you outsource CAD design services to experienced CAD agencies, there is often confusion about whether to opt for 2D CAD drafting or 3D CAD modeling. Following are some main differences between the two.

  1. Hardware requirements: No extra specifications are needed in your computer for using 2D CAD. However, you need to invest in higher-performance machines for 3D CAD modeling.
  2. Simple vs complex structures: You can work with 2D CAD dealing with layers, line types, and line weights. When the structure is more complex, 3D CAD modeling will be more appropriate.
  3. Client interface: 2D drawings can be difficult for clients to understand. 3D CAD has a better client interface, allowing you to convey the design intent and an idea of the end product to be expected.
  4. Clash detection: 3D CAD makes detecting errors and clashing elements easier and quicker. This is a struggling area with 2D CAD.
  5. Purpose: While 2D drawings are mainly for technical purposes with no visual aspect, 3D CAD modeling is visually orientated. So, visualization is easily accomplished. 

Advantages and disadvantages of using 2D CAD drafting and 3D CAD modeling:

2D CAD advantages:

  • A very cost-effective alternative
  • Simple to learn, with little investment in the training of the employees.
  • Formatting is easy and sharing data is quick and convenient.


  • A bit too simple, just an extension of manual 2D drafting.
  • Redrawing and performing repetitive tasks or modifications is tough and time-consuming.

Advantages of 3D CAD modeling:

  • These models are intrinsic and detailed. 2D rendering is also included.
  • Editing, rework, and modifications can easily be performed quickly and accurately.
  • User and client-friendly. Good client interface.
  • The power of visualization allows you to experiment and innovate.


  • Cannot be used without a high-performing machine.
  • High investment in equipment and training of employees.

Hire CAD architectural design services to make the design process more creative and efficient, faster, and mostly error-free in order to produce excellent designs regularly. You have a choice to use either 2D CAD drafting or 3D CAD modeling as per your project requirements; although architects prefer going for 3D CAD modeling for many reasons.
