@Pierreden:
...when i select it from plugins sub-menu nothings appear(no menu) & selection(mouse left button) stops working ,and it can't be deactivate from plugins sub-menu.until i select a tool from toolbar..and then it makes it deactivate!
it's a complicated situation that i can't explain in better way !

@ TT : well done ! it's great plugin .

thanks Rich !

i've designed a theatre building model and i want to export an "obj" file format for using in Autodesk Maya.and then i want to make an animation, including camera movement all around the stage and auditorium , other kinds of movement such as stage curtain opening and closing , rotating and moving up&down podiums (dynamic part of stage surface) and simple lighting based on default light fixtures .
is it possible?
if the answer is "yes" does Maya recognize Sketchup textures?
can i modify my exported model in Maya?
this is my thesis project and i appreciate any kinds of tips and information .

i found it out !
i haven't checked tools in UI !
thank u anyway
