3D sketching is a visual programming technique that allows you to create 3D models and animations by drawing in 3D space. Sketching in 3D space allows you to create complex and intricate forms by moving and rotating your drawing object in 3D space.
With 3D sketching, you can create models and animations of virtually anything! You can create models of buildings, machines, humans, and more!
3D Sketching is the process of creating 3D models using a 2D drawing or image as a base. This allows you to create 3D models without having to learn complex 3D modeling software. 3D sketching can be as easy or as complex as you’d like it to be. You can mimic real objects or objects from other industries, or you can create your own designs.
3D sketching is a freehand drawing technique where you draw 3D objects on a 2D surface. It’s a great way to practice drawing shapes and objects while also learning about perspective. It’s also a great way to practice drawing hands, faces, and other human bodies. 3D sketching is a great tool for artists of all levels.
How can 3D sketching be used in design and engineering?

In this article, you’ll learn about the various uses of 3D in the industrial design process, and see how designers and CAD modelers are done making sketches that can be used to create finished products.
Converting a sketch to 3D is a fairly straightforward process; all you have to do is add a third dimension. In many engineering environments, 2D drawings created with free CAD software are the official specification (design authority or authoritative record) of the finished product, and are often associated with 3D CAD. – Use computer-aided design software to create and visualize the three-dimensional, geometrically correct digital model of the object.
Sometimes 2D drawings are used as complete product specifications and may contain other important information to help identify assembly or inspection instructions and other useful data.
To ensure that 3D engineering standards are met in our CAD drawing services, we engage some of our in-house engineers to review the drawings.
3D Engineering Solutions product design knowledge and skills are transferred directly to our CAD modeling and drawing layout service. At 3D Engineering Solutions, we employ experienced and certified engineers to create well-designed CAD modeling services designed to help your business succeed.
We have the ability to easily integrate our customers’ product-specific ideas into their 3D CAD designs and make significant innovative contributions to the final product.
What are some benefits of using 3D sketching?

- There is no doubt that good designers need to communicate their ideas through sketches, but doing so in a 3D model is an added bonus. Modern 3D modeling provides design depth that is not possible with rough sketches or 2D designs, such as greater control over details. The popularity of 3D modeling continues to grow for engineers who want to “see” a finished structure, product, or part during the design process.
- Film, video games, architecture, construction, product development, medicine – all these industries use 3D models to visualize, simulate and visualize graphic design. Three-dimensional images help to model various objects in architecture, mechanical engineering and other industries.
- 3D models in AEC design are typically for buildings and building systems, but they can be used to fabricate individual components and devices as you get closer to building construction.
- For large structures, sophisticated 3D modeling software can be used, including designing structures with unique arches and extensions. Modeling techniques can be used to communicate material type, size, etc. This model can then be used to validate designs, improve concepts, or form the basis for 3D CAD models that can be built using parametric surfaces.
- In addition, working with a 3D model makes it easier for designers to use 2D layouts and packaging models. Templates make it relatively easy to make major design changes because the drawings are based on 3D geometry rather than lines. 3D modeling not only helps designers and end users visualize space requirements, but also improves the efficiency and accuracy of drawings.
How Does 3D Sketching Differ From Traditional 2D Sketching
Using a 3D CAD model, we can see the final product, but most people can understand the design. The 2D drawing is a sectional top view, front view, side view of the building, 3D models will provide a visual aspect and display the design idea in maximum detail.
In the construction area, one 3D model will represent all 3 sides of the building. In the construction area, the 2D drawing can only show us every part of the building in the construction area, such as the facade, plan, and side.
With the concepts above, you can also clearly see the difference between 2D and 3D modeling. 3D modeling not only helps designers and end users visualize space requirements, but also improves the efficiency and accuracy of drawings.
Additionally, 2D and 3D modeling have some advantages when designing buildings using 3D models instead of 2D drawings. Wireframe models can also serve as the basis for building 3D surface and solid models, and can provide geometry for 2D drawings.
Compared to 3D surface and solid models, 2D drawings offer fewer options for presenting and displaying ideas, and limited options for product design analysis and testing.
Unlike a 2D drawing, which includes an annotation indicating the material assigned to a product, and a 3D surface model showing the representation of the material on surfaces, a 3D model can be assigned a material that accurately reproduces the material used to make the product.
Mechanical and functional components can be part of all parts of any retail project using 2D and 3D drawings and models. The move to detailed retail design is expected to be a step towards greater success, ultimately favoring retail BIM modeling over retail design drawings alone.
The use of 2D and 3D drawings and CAD renderings can help retail store designers develop the functionality needed for smart store design before the actual retail space creation process begins.
Specifically, designers can now fine-tune the specific details of their drawing with greater precision, experiment with different types of surfaces, work with mirroring tools to stretch a 2D shape into a 3D object, achieve better finishes on sketches and models, present designs in real time , and bring your designs to life with 3D printer compatibility.
Designers work in 3D CAD using tools such as CATIA, Creo, Inventor, NX, SOLIDWORKS and others, however product and process information is then projected into 2D drawings, some of them on paper, that are not machine readable.
Traditional CAD drafting software and existing 2D drafting software cannot realize parametric design.
In the traditional design, CNC machining is a drawing based on a CAD design, so there are bound to be two sets of data of the same part in CAD and CAM, which can easily lead to management confusion. 2D and 3D construction drawings are created using black ink on white paper, often with horizontal, vertical, and diagonal lines to create a three-dimensional appearance, but the image itself remains flat.
