Seven Best Online CAD Software 

1. SelfCAD (Overall Best Online CAD Software)

SelfCAD is an online 3D modeling software that one can use both online and on Windows and Mac. You can design both simple and complex designs and even prepare them for 3D printing in the software without the need for additional software as it has an in-built 3D slicer that is compatible with most of the common FDM 3D printers.  It also takes only a few hours to become proficient with this 3D CAD program because it is simple to use. The video below shows the overview of the software.

SelfCAD comes with numerous tools and features for designing and modifying your designs. For example, there are shape generators that you can use as primitives for your designs. There are freehand drawing and sketching tools to use to create designs from scratch. There are easy-to-use selection modes to use to select edges, faces, and vertices of your models and modify them based on your needs. 

SelfCAD also comes with other interesting features like the image to a 3D model that you can use to turn any image into a 3D model with ease. There is also a powerful rendering engine that one can use to create realistic renders of the design easily. SelfCAD also has an animation tool useful for creating simple animations. SelfCAD is a significant next step for those just starting out with digital design because it's very user-friendly. Hence included in this list. It does fill in some gaps for this list with a few extra features like mesh modeling that will allow users to experience other facets of CAD and 3D modeling, as well as some practical tools for those planning to 3D print their models.

2. Cedreo

Cedreo is a cloud-based designing software built for home builders and interior designers. Features of Cedreo include; 

• 3D Home Design: Cedreo allows users to create and customize 3D models of homes, buildings, and interior spaces. Users can design floor plans, add walls, windows, doors, and various architectural elements.
• Catalog of Building Elements: The software usually provides a catalog of pre-built architectural elements such as furniture, appliances, fixtures, decor, and landscaping objects. Users can easily drag and drop these elements into their designs.
• Material and Texture Library: Cedreo typically includes a library of textures and materials to apply to surfaces within the 3D model. This helps users visualize different building materials like wood, stone, tile, paint colors, etc.
• Real-Time 3D Visualization: Users can view their designs in real-time 3D to get a better sense of the space and make quick adjustments to the design.
• Customization Options: The software often provides various customization options to tweak the design elements, such as adjusting dimensions, scaling, and adding personalized features.
• Lighting and Shadow Simulation: Cedreo might simulate natural and artificial lighting to visualize how light affects the interiors and exteriors of the building at different times of the day.
• 2D Floor Plans: In addition to 3D modeling, the software often enables users to generate 2D floor plans and export them for documentation and presentations.
• Collaboration and Sharing: Cedreo usually allows users to share their designs with clients, team members, or collaborators, enabling seamless collaboration and feedback.
• Cost Estimation: Some versions of Cedreo might include tools to estimate material and construction costs based on the design, helping users with budgeting and project planning.

3. TinkerCAD

TinkerCAD is a simple web-based 3D design software that is mostly for beginners and those. The idea behind this free online CAD program is that you can modify 3D shapes by dragging and dropping them onto a functional grid. Only a fast Internet connection and an input device are required for work (a mouse, tablet, or even a laptop trackpad will do). 

Autodesk's TinkerCAD is an entirely free solid modeling program that primarily targets children and CAD beginners. It uses simple shapes that are either solids or holes to logically create models using boolean differences. The software's simplicity often makes it the quickest method for creating simple designs, going beyond its intended audience to entice even seasoned digital designers for urgent jobs. However, once you gain experience with 3D modeling, you'll probably ignore it when creating even simple parts.

Because TinkerCAD is a web-based program, you can work on your projects from various devices and simultaneously collaborate with others. There are many ways to create models using this simple online CAD program. You can import and edit models from other programs in the.STL, OBJ, and.SVG formats, as well as create your own designs or edit the finished models of other TinkerCAD users. You can download and print other users' models in different file formats to TinkerCAD too. You can also export your own models in most of the commonly available file formats.

4. SketchUp

SketchUp is a powerful and easy-to-use 3D modeling software that enables users to create complex models with a minimum of effort. With its intuitive interface, SketchUp is suitable for beginners and experts alike. SketchUp can be used for a variety of purposes, such as architectural design, interior design, landscape design, and more.  While SketchUp Shop won't provide you with the same desktop CAD experience as some of the other options on this list, becoming familiar with the SketchUp ecosystem now will help you later if you decide to upgrade to a full-featured professional CAD program.

There are many uses for SketchUp, a 3D modeling program that allows users to create detailed models of just about anything. One common use for SketchUp is architecture. Architects can use it to create models of their buildings, which can be helpful for 3D visualizing the finished product and for showing clients. SketchUp can also be used for interior design, landscape design, and just about any other type of design. Additionally, many people use SketchUp to create models for 3D printing. With its easy-to-use interface and wide range of features, SketchUp is a versatile tool that can be used for a variety of purposes.

5. Vectary

Vectary is another online CAD software that you can create, share, and edit 3D designs. Vectary combines subdivision modeling, parametric plugins, and common mesh modeling. These open-source online CAD tools have a complete set of tools and an infinite number of models that can be exchanged. You can 3D print most of the models you make using this free online CAD program.

Vectary is a unique parametric modeler, a system frequently used for the most complex engineering designs, but it focuses on artistic applications over technical engineering and design applications. Indeed, this modeler isn't a "pure" parametric one. According to the designers, Vectary is a hybrid that "combines mesh modeling, subdivision modeling, and parametric design." It doesn't have all the fine tunings that some CAD software with a stronger engineering focus does, but it still performs excellently with a few appealing and distinctive features.

Every model you produce in the browser is saved in the cloud under your account. The user interface of this free online CAD design software is simple. On the community platform Vectary, anyone can share and edit 3D models by changing settings or the mesh of other creations.
