A question about dynamics

I don’t use dynamics very much but I had the occasion to (of course when the forums were down) and I ran into some confusing stuff.

I have both the table cloth and sheets. I am using DS4.  I can only find a .daz file for the king sized sheet and the round table cloth in my files.  I reset the downloads and reinstalled thinking that perhaps something went wonky when I migrated my database over when I fully converted to DS4 but to no avail, I still only have one size sheet and one shape table cloth.  From the product pages I know I should have 4 sizes of sheets and back in DS3 I know I had the square and round tablecloth shape.

I finished the project I was working on without them but I would appreciate any help figuring out where these files might have ended up or even what files I should be searching for.

Thank you.

It works the same way as in DS3—on the Dynamic Clothing tab select the bottom and use the pulldown at the bottom to change shapes.

I have been working on a rigid body subject quite a long. But till now there is an unresolved question for me. When we calculating the torque acting on the rigid body we use the following definition of the torque: t = r X f, X - is a cross product. So if I calculate the torque in a body-fixed system I use r in the body-fixed system too, but for force f - I am not sure. In which coordinate system should it be expressed - in the body-fixed or in space-fixed. Are this forces different in both systems? Sorry, for probably stupid questions. Thanks
