I have a challenge that I need help figuring out. I have a shape that is like a quarter of a torus. It is a short radius 45 degree pipe. It is a model inside of a CAD program. I am able to calculate the internal volume of the shape in square inches. The volume is 90.98 square inches. However, I need to account for a change in the geometry; and adjust the internal volume. The change in the geometry was that I added a .5 inch wall thickness to the walls of the model. With this in mind, how could I adjust the internal volume to reflect the change without actually remeasuring the internal volume of the adjusted geometry? Any help would be appreciated, thank you!

Did you mean cubic inches? Also, did you mean 45 degrees? That is a quarter of 180 degrees, whereas one might expect 360 degrees to correspond to an entire torus. What do you mean by "the walls of the model"? Why would the interior of the torus change size without your knowing by exactly how much?
