Hi,
I drew a box with width,lenght,height are the same 50,then a get the vertices coordinates are
(-25,-25,0,25,-25,0,-25,25,0,25,25,0,-25,-25,50,25,-25,50,-25,25,50,25,25,50)!Sure,3ds max consider the center of it as origin point of local frame of it!Then i wonder that how can i change the origin point of local frame???

You’d need to be more specific about your goal. Anyway, you should check SDK help Object Offset Transformation section. In short these are main methods

Hope it helps,

Acutally,what i meant is an operation in 3ds max,not these functions,so,if i draw a box in 3ds max,the origin point of local space is default in the center of bottom of this box,so,i want to know if i want to change this position,then these coordinates will be changed!Thank u!

It seems it’s not the best forum for your question. Anyway coordinates of vertices will depend on your space context. These points can have totally different coordinates in world space, transform space or mesh space. You need to specify which one you’re interested in.
