Not directly, you will have to do part (most) of the work. You will need to project your bodies onto the planes. You will probably need to generate silhouette lines on your part with the Split Line tool, using the Silhouette option.Put sketches on the planes, then generate the outline of your body by Convert Entities using the silhouette lines. Check to make sure that the sketch outline is closed. Close out the sketch and use Tools/Section Properties to measure the area of the sketch.
Here's hoping there is an easier way.
