Hey, I have problem with generating surgical guide.  
I tried to make sure nothing collides with central sawboxes, tried different sizes od bigger sawboxes, changed fiducial plenty of times and yet I always get this error.  
I wish it said what I am doing wrong…

Here are the screenshots, I hope they upload well…

Hi, I’m the main developer of this extension

From your pictures, I don’t see anything that is obviously wrong with your plan. If you could upload the Slicer scene as .mrb file and share it with me privately I could check

Please see this link:

> **[Data Loading and Saving — 3D Slicer documentation](https://slicer.readthedocs.io/en/latest/user_guide/data_loading_and_saving.html#save-data)**

After you have the .mrb file, you can upload it to the website of your preference, and send me the link privately using a Discurse message

Also please let me know which version of Slicer are you currently using (e.g. Slicer 5.8.1 or Slicer 5.6.2)

I was trying to send a private message but there doesn’t seem to be the letter icon anywhere.

There’s also no letter when I enter your profile.  
As I’m quite new to this what hosting platform would you recommend for me to put this scene on?  
Thank you for your answers and for your patience.

Hello, I’m having this exact same problem. I wonder if you was able to solve this. I’m using the 5.8.1 version. Should I downgrade?

It should be working. Did you check you have the Sandbox extension installed? If that does not help, please send me the correspoding Slicer scene to your surgical plan so I can review and help a bit more
