2. Start the Import Process.

  • In the Design Manager, click More > Import. 

  • Browse to the folder or location where your design files are stored. 

  • If your files are on a USB drive, use the uDisk tab to access them. 

3. Choose the Correct File Format.

  • Select the design file you want to import. 

  • The software is compatible with a wide range of file formats. 

  • Universal format such as DXF or XML are recommended because they can be exported from most CAD software. 

4. Import Separate Design Layers if Needed.

  • The example shows two separate files:  

  • one for the strings

  • one for the tin/surface

  • Keeping them separate gives you more flexibility because you can toggle them on and off individually. 

  • If both are combined into one file, that is also acceptable. 

5. Import the First File.

  • go to Designs

  • select the surface file 

  • click Import

  • Once imported, the surface will appear in the project as well.
