different calculations

[CETLV]

I ran into something a little different today.  Why do systems calculate with different results if you calculate selection vs all objects?  

Greens are calculate selection vs reds on calculate all?

 

Its a simple 20ft system with 2 motors pulled from a more elaborate file.

Hi CETLV,

are definitely only the objects that we see on the picture in the drawing?

When calculating "All" Braceworks consideres also objects that are hidden.

 

I would take a look into the file if you can share it.

There are no hidden objects that are playing on this simple system.

 

I have been playing around with this in my bigger systems as well.  Selecting individual systems they all calculate out, but trying to calculate all (even though the systems do not interact together at all) causes negative weights and all hoists to fail.  

 

I was hoping to just see if there was a difference in equations or order of operations in the math between the two calcs.

Whenever I run into these kinds of issues, I copy and paste the offending parts into a blank drawing and try again. Not that this will help, it's just another step in the search of a solution.
