Read below to learn why are companies and firms moving from 2D to 3D CAD architectural renderings and models. 

2D rendering and its uses 

2D rendering is commonly used in architecture, planning, landscaping, and civil engineering. This process involves using programs such as Photoshop to enhance flat drawings created through 2D CAD design services by adding shadows, texture, and color. In 2D renderings, colors are often used to indicate different functions or use rather than to convey realism.

To create a 2D rendering, starting with an existing drawing, which can be a hand-drawn sketch or a computer-generated image produced through 2D CAD drafting services, is essential. Examples of drawings that can be transformed into 2D renderings include building elevations, floor plans, and site plans. The primary purpose of 2D renderings is to add visual interest and clarify design elements rather than to depict realistic depth.

Historically, 2D renderings, including 2D drawing and floor plan design services, were often created using markers or enhanced with watercolor paints to achieve a wash effect. Today, digital 2D rendering software provides a convenient and efficient way to create renderings. Despite the prevalence of digital tools, traditional hand rendering remains a valuable skill and continues to be appreciated for its artistic qualities.

Hand rendering has the potential to produce stunning art pieces that are unique and expressive, ensuring its continued relevance alongside 2D CAD design and drafting services, as well as 2D drawing and floor plan design services, in the world of design and visualization.

When to use 2D and 3D rendering for projects 

In a project’s early stages, 2D CAD design helps communicate preliminary ideas effectively and secure initial approvals. However, 3D rendering benefits marketing and stakeholder buy-in as the project advances. 3D renderings offer a realistic, immersive representation of the final product, aiding in design feedback and better communication of your vision.

3D modeling design services play a pivotal role in enhancing the flexibility and efficiency of the design process. One of the key benefits of utilizing 3D rendering, as facilitated by 3D modeling design services, is the ability to make design changes efficiently and quickly. This flexibility enables iterative design exploration and allows designers to experiment with various design options without requiring manual revisions. It empowers designers to refine and perfect their projects, achieving their design objectives more efficiently and precisely.

Differences between 2D and 3D CAD architectural renderings and models

The advent of CAD revolutionized the design industry, replacing traditional drafting tables and transforming how designs were created. Today, as 3D modeling becomes increasingly widespread, it further shapes the landscape of project design, construction, and management. 2D to 3D modeling services play a vital role in this transition.

Despite the numerous benefits that 3D modeling offers, 2D CAD remains prevalent in architecture, often due to a common misconception among architects that using 3D architecture software will be time-consuming because it requires additional details. However, in practice, 3D modeling is often notably faster than 2D CAD, streamlining the design process and enhancing overall efficiency.

Learn how these two different methods compare to each other. 

  • Quantity calculation

3D CAD: With the assistance of BIM Modeling services, quantities can be derived automatically from the 3D BIM model with the click of a button. This automation streamlines the process of generating accurate quantity reports.

Additionally, suppose there is a change in the model. In that case, the report can be easily rerun to reflect the updated information, ensuring stakeholders can access the most current data. BIM Modeling services are pivotal in enhancing efficiency and accuracy in quantity reporting.

2D CAD: You can use 2D drawing to provide different areas of shape that can be manually collated into a bill or schedule of quantities. The quantities will have to be calculated again if any change is made. 

  • Development of section views, elevation, and plan

3D CAD: Views are created from the 3D BIM model by positioning viewports in the relevant areas, a process facilitated by architectural BIM services. Similar to creating a section cut in a 3D model, any changes to the model will automatically update the views, ensuring consistency and accuracy. As a result, architectural BIM services enhance the efficiency of the initial creation of views and simplify the management of design changes.

2D CAD: Every view must be manually drawn in 2D, increasing the risk of inconsistencies and errors creeping into the design. If any changes in the scope occur, the edits will have to be made individually to every view, which can result in the risk of discrepancies while increasing the time needed for updating the design.

  • Drawing openings and walls

3D CAD: 3D modeling tools and 3D floor plan design services make designing walls in 3D a seamless process that requires only a few clicks. Walls can be inserted at the correct size and come pre-hatched for convenience. Any wall openings created will automatically have a thickness that matches the walls they are inserted into, and the height of the opening is defined during the insertion process.

Additionally, door and window symbols are placed automatically, with the correct direction set effortlessly with just a few clicks. Overall, 3D floor plan design services enhance the efficiency and accuracy of architectural design, streamlining the process of creating detailed and realistic floor plans.

2D CAD: The designer must draw individual rectangles or polylines when drawing 2D walls, trim them where conjunction occurs, and fill them with the preferred hatching. Other openings like doors or windows must be made using blocks or from polylines, changing the position with the use of commands like a mirror, rotate, and move.

  • Visualizations and rendering

3D CAD: Using an integrated rendering engine, you can quickly render 3D models in just a few minutes. Using models for visualizations guarantees a precise result that presents the building the same way it was designed. 

2D CAD: Visualizations and rendering must be recreated in a different program that relies on the details in 2D drawings to make the final product. 

  • Room stamps

3D CAD: Room stamps are quickly made using intelligent labeling tools. For instance, floor areas are calculated automatically and can be placed in the drawing as a parametric label that reacts to changes in the drawn rooms. 

2D CAD: With the assistance of architectural drawing services, designers can accurately label every room in a design using text boxes. In addition to labeling, the floor area of each room must be manually calculated or obtained from a rectangle’s properties. This calculated floor area is added to the room stamp by editing the text, providing clear and precise information about the room’s dimensions.

It is important to note that this process must be done separately for each room the changes affect, ensuring that all modifications are accurately reflected in the architectural drawings. Architectural drawing services streamline this process, enhancing accuracy and efficiency in design documentation.
