pos/neg - posbody/negbody in pm file.

pos/neg - posbody/negbody in pm file.

could someone explain to me the difference in these and how to know when pos means positive and when it means position?

 

(Left+/Right-, Up+/Down-, Fore-/Aft+)

"pos="/"neg=" are positions, think of them as points in 3d space.
Posbody/Negbody are links to other references.

For all of the bars Posbody=body, Negbody=upright.

The only place this changes is the link from wheel to spindle. For those the Posbody is the wheel, Negbody=upright.

 

so these are two different positions? as in the distance of travel?

 

Pos/neg are the end points of the parts defined by posbody and negbody (end point locations in space of the model)
