Installing a new model

To install a new model:

1. Put all the model files (.pro, .geo) in a directory, which should also contain a file named infos.xml with the model information:

   <?xml version="1.0" encoding="utf-8"?>
   <models>
     <model>
       <title>Your model title</title>
       <summary>Your model summary</summary>
       <file type="pro">your_main_pro_file.pro</file>
       <preview type="png">your_128x128_pixel_screenshot.png</preview>
       <url>http://your_model_website.com</url>
     </model>
   </models>
   

   (See e.g. Inductor or Waveguides.)

2. Zip the directory.
3. Open the .zip file on your device (e.g. through iCloud, Dropbox or Google Drive; or by emailing it to yourself and opening the attachment; or by putting it on a web server and downloading the file on the device with Safari or Chrome).

The new models will be extracted alongside the app's built-in models.
