We’ll assist you in locating the best SketchUp alternatives that have equal or superior features. From the list below, you may pick the finest free or paid 3D modelling software for your needs. Let’s get this party started.

What is SketchUp?

SketchUp is a popular 3D CAD tool used in architecture, engineering, and interior design, as well as sculpting, robot creation, and 3D printing. Its plugins provide additional assistance and are known for their intuitive, user-friendly UI and built-in capabilities. SketchUp, which is available in both free and paid editions, has dominated the industry for over 20 years.

Its 3D Warehouse is a model collection consisting of furniture and building ideas that you can quickly incorporate into any project. SketchUp is one of the best free 3D modelling applications because of the built-in templates. However, it, like other software, is not capable of meeting everyone’s needs. So, let us assist you in locating the greatest SketchUp substitute.

Top 15 SketchUp Alternatives (Free 3D Modeling Software) in 2021:

1. SolidWorks

SolidWorks, a Microsoft Windows-based competitor to SketchUp, is one of the best. It can be used to create 3D solid parts and model assemblies. It allows us to compare two designs, either their geometry or views, utilising Face Comparison, View Comparison, and Geometry Comparison. It is known for its intuitive interface, comprehensive standard library, easy hole-drilling, and tapping choices.

Faces, loops, edges, and features can be selected based on a variety of geometric parameters. We may compare two SolidWorks documents and examine the various thick and thin sections using the analysis tool. As a result, you can locate and make essential adjustments within models using this 3D Design programme. It is available for download from the company’s official website.
