 To create a 3D mask, you just need to set an ROI using the "Set perspective's ROI" button for one or more perspectives, though at least two are recommended. **Any of the ImageJ selection tools can be used** to generate the ROIs, with the exception of the straight line tool with a line width of 1 and the multi-point tool. After setting the perspective ROI, the ROI selection will be cleared from the image, but can be retrieved again by clicking the "Get perspective's ROI" button. The "Reset perspective's ROI" button can be used to reset the ROI to the default ROI, which is the full image from that perspective (equivalent to the Select All command). This allows the user to modify existing perspective's ROI's if the preview looks incorrect (discussed below). This is generally best done by using easily-modifiable ROI tools (like the polygon tool) and clicking the Get then Reset buttons before adjusting the ROI.

 ### Using ROI Manager
-ROI manager can be used to create multiple objects in your exported mask. You can do this by adding as many selections to the manager as usual, then select all of those selections in the list, and click More >> OR (Combine). This will create one selection from all of those, and then click "Set". This can be a challenge if you are using ROI manager for multiple perspectives, as you'll need to keep track of which persepctive each ROI in the list is for. Additionally, the "Get" button will not be as useful, as it does not return these ROIs to the ROI manager and these multi-element ROIs are not as easy to manipulate, though some functions in the Edit > Selection menu do work.
