  3. Use Cases:
    • Excellent for producing floor plans, diagrams, and layouts.

Running Windows CAD Software on Ubuntu

While popular CAD applications like AutoCAD and SolidWorks don’t directly support Linux, there are workarounds:

Virtual Machines

Using a virtual machine is one way to run Windows-based CAD software on Ubuntu.

  1. Install Oracle VirtualBox:

    • Run sudo apt install virtualbox in your terminal.
  2. Set Up the Virtual Machine:
    • Create a new VM and install a Windows operating system.
    • Once Windows is running, you can install your desired CAD software.

Using Wine

Wine is another alternative to run Windows applications on Linux. While not all software will function perfectly, it is worth a try for lightweight applications.

  1. Install Wine:

    • Open the terminal and type: sudo apt install wine.
  2. Run the Application:
    • Download the Windows-based CAD software installer.
    • Execute it using Wine by running: wine setup.exe.
