Hi everyone,

I’m experiencing an issue while trying to create two baffles on the same model. Unfortunately, whenever I add a second baffle, it seems to overwrite or delete the first one, as shown in the attached image.

Could anyone please help me figure out how to resolve this problem? I suspect this might be a common issue, so any guidance would be greatly appreciated.

Thank you in advance!  
John

You can have any number of baffle surface models. Tpu can add a new one by right-clicking on the baffle model selector and choose to create new.

Dear Andras,

Thank you for your prompt response. Unfortunately, it’s still not working. I started from scratch and followed the steps to create a new baffle from the other closed curve. While it does create a new baffle, it deletes the previous one (Create new model was selected). That’s why I’m reaching out for help. I’ve attached a screenshot that shows the two closed curves, but only one baffle is crated.

Best regards,  
John

Thank you, I see now. This was an unnecessary limitation, I’ve fixed it now. You can either make [this change](https://github.com/SlicerHeart/SlicerHeart/commit/7b4e534fd1ee1a6a57e5daa6bef9ca2a27c99bb8) in the .py script on your computer now, or update the SlicerHeart extension tomorrow.

Thank you, Andras! It’s working smoothly now.
