• Complex interface: Might be overwhelming for beginners without prior experience in Bentley software.

5. DraftSight: DraftSight is a professional-grade 2D CAD product from Dassault Systèmes, the makers of SolidWorks. While DraftSight is primarily known for 2D drafting, it can be used for creating piping schematics.

Features:

• Familiar interface: Similar to AutoCAD, making it easy to transition if you're already familiar with that software.
• Wide format support: Can open, edit, and save DWG and DXF files.

Benefits:

• Free version available: A free version with basic functionality is available for download.
• Cross-platform: Works on Windows, macOS, and Linux.

Drawbacks:

• Limited in the free version: Some advanced features are only available in the paid versions.
• 2D only: Not suitable for those who require 3D modeling capabilities.

6. DesignSpark Mechanical: DesignSpark Mechanical is another great option for engineers and designers looking for free piping design software. While it's primarily a 3D CAD tool, it can be adapted for piping design purposes.

Features:

• Intuitive user interface: Designed to be easy to use, even for those new to CAD software.
• Direct modeling: Allows for fast and easy modifications to your designs.
• Extensive library: Access to a wide range of parts and symbols.

Benefits:

• Completely free: No cost to download and use.
