Watch this instruction video about its functioning or read the following text: Download a 3D-PDF to enable the interactive options. The 3D-PDFs can be opened on any computer as long as the Adobe PDF or equivalent reader is installed. A 3D- PDF becomes activated by “clicking” with the mouse on the reconstruction. A toolbar appears at the top of the screen that includes the option “model tree”. The model tree displays a material list of structures in the upper box, and preset viewing options (cameras) in the lower box. The sequence of items corresponds to that in Supplemental Table 3. The list of visible structures can be modified by marking or unmarking a structure. To manipulate the reconstruction, press the left mouse button to rotate it, the scroll button to zoom in or out, and the left and right mouse buttons simultaneously to move the embryo across the screen. A structure can be rendered transparent by selecting that option from the drop-down menu after selecting the structure with the right mouse button. To inspect a combination of structures, one is advised to build up the composition, beginning with a familiar component, such as a lumen, rather than deleting non-relevant structures one-by-one from a completely reconstructed specimen.
