Dear community,

I have strange behavior with machine simulation. 
On this picture it is ok. It is the master operation, as you can see, the "X" direction is "1" :

But as you can see on the picture below, my tool is upside down, the "X" direction is "-1"...but i have just inserted a "copy operation", it is  a translation :

very strange and i have to say that the APT file is OK : the direction is "1" in X, and i  just finished machining the part in real which is good.

I have the same pb with another opération in the process : as you can see on the picture below, the coordinate is "+197.839" but the tool is positionned in "-197.839"...

Here my process in 3dXml : 

Great thank's

Laurent
