hello, when i import file from sketchup in which i draw pipes or other objects with xyz on the center, then export in dae format, the pipes i draw have positions xyz i don't understand, looking like : position values = Y 551,1801 Z 36,3582 / world values: Y 0,9235 Z 14. Can someone explain me those differences? knowing that the specific origin of the pipe is in its center, i don't get it. and sometimes y and z are inversed in the position values when they hould be similar to world (that's the case in sketchup.) Can anyone help?
