unwanted snapping in layout editor

Hello,

I am using Virtuoso 6.1.6-64b.

When I draw a 10 um path with metal layer on the vertical direction, then I want to draw another thinner path on it with the same metal layer in the horizontal direction,

the editor force the second path to start from center of the first thicker path, moreover, depends on the direction I am drawing this second path, the editor changes the first path accordingly.

The gravity is set to none, and the options of the path when pressing F3 doesn't show snap to edges or center, just snap mode (orthogonal, diagonal, L90XFirst, L90YFirst)

How can I draw this second path without any modification in the original first path ?

Thank you.

H.A.
