Modification of Tissue Volumes in the Anatomical Model
-
Could you please explain how to modify the volumes of the bladder and rectum while simultaneously deforming the surrounding tissues? Additionally, I am unsure how to view tissue cross-sections. Since I am a beginner, I would greatly appreciate a detailed explanation.
Thank you for your assistance.

There are two possible ways to change the shape and volume of an organ.
First approach uses the "Stretch" option available under the "Move" tool. When following this approach, first create a copy of the tissue you are interested in (e.g. bladder) and use the stretch tool to scale it to the desired dimensions. Afterwards, insert the modified tissue back into the original model by placing it in the proper location while still keeping the original one. When setting up your simulations make sure that the new modified tissue has higher priority compared to the original one and overwrites it. This prevents the introduction of holes.
Second approach is via the "Morphing Tool". There is another post showing how to generate a deformation field and how to apply it to the desired organ first and later to the whole body. Please check the following post:

I would add that in the first approach you might change the tissue property of the original bladder to something else, e.g. fat, to get the desired effect of shrinking or stretching the bladder without creating air holes.
Btw, you can measure the volume of a tissue surface in the modeler using the measure tool.
