Re: Scaling of the feet

Hi Erica, I'm glad we seemed to figure out the issue! I wanted to make sure that the numbers I mentioned during your call were documented somewhere for your records. The model when first opened is opened with the mass center of the pelvis located at ground y = 0, but using gait 2392's ground platfor...
