Thanks Emmanuel,

That is actually helpful to set some attributes, but I need to do something more.

I'm designing a furniture made of blocks of different sizes and positioned on different places to form, let's say, a box. The "X,Y, elevation" coordinates of one block are dependant on another ...

Hi,

Is there a way to use variables to fill positions (x,y), dimensions, etc?

I mean, I have many items that have the same width and would like to change it modifying just one variable.

Is that possible?
