Hello All, I'm experiencing a strange experience. It may be my code, but i don't know where is the mistake. I need, by script, to enable the option "Use True BBox" in my layout. So i tried, in my script: envSetVal("layout" "useTrueBBox" 'boolean t) But nothing happens :( i mean i can not see any changes in the layout. But when i use the display option form, all is fine. I would not prefer to use the .cdsenv for this variable, because i want the script to take care of everything. (and i'm sure some of my users will complain if i ask them to change their .cdsenv !!) I'm sure i'm missing something, but what, and where ? Do you have any idea ? Thanks a lot for your help :) best, bubu
