Is Google Sketchup still good to use in 2018 or is there better software now?

In 2018, Google SketchUp had already transitioned to Trimble SketchUp, and it remained a popular choice for 3D modeling, particularly in fields like architecture, interior design, and woodworking. It's known for its user-friendly interface, quick learning curve, and a large community that shares models and resources.

Whether Trimble SketchUp is "good" for your specific needs depends on your requirements. Here are some considerations:

1. Ease of Use: SketchUp is known for its intuitive interface, making it accessible for beginners. If ease of use is a priority, SketchUp could be a good choice.

2. Free Version: Trimble SketchUp offers a free version known as SketchUp Free. This can be suitable for many users who don't require the advanced features found in the paid versions.

3. Extensions and Plugins: SketchUp has a vast library of extensions and plugins, enhancing its capabilities. The availability of these additional tools can significantly extend SketchUp's functionality.

4. Professional Versions: Trimble SketchUp also offers professional versions (SketchUp Pro) with additional features, including layout tools for creating 2D presentations and documentation.

5. Industry Trends: Depending on your specific industry, other 3D modeling software might be preferred. For example, in architecture and design, software like Autodesk Revit or Rhino may be commonly used.

6. Parametric Modeling: If your work involves complex parametric modeling, especially in engineering or product design, dedicated CAD software like SolidWorks or Fusion 360 might be more suitable.

7. Updates and Improvements: Software is continually evolving. Check for the latest updates, features, and improvements in SketchUp to see if they align with your needs.

If you're looking for alternatives, consider software like Blender (free and open-source, suitable for various 3D modeling tasks), Autodesk Fusion 360 (parametric modeling and CAD), or Rhino (commonly used in industrial design and architecture). The choice depends on your specific workflow, industry, and preferences.

Before making a decision, it's a good idea to try out different software options, explore their features, and consider your specific requirements and workflow. Additionally, check for the most recent reviews and recommendations from professionals in your field.
