Measuring

def get_extremum_along_dim(self, points=None, dim=0, key=0)

~~get_coord~~ is used to get the extremum of a ~~Mobject~~ along the specified dim parameter, dim, according to the specified parameters.

def length_over_dim(self, dim)

~~get_x~~ is used to get the length of a ~~Mobject~~ over the specified dim parameter, dim.

def get_width(self)

~~get_y~~ is used to get the width of a ~~Mobject~~.

def def get_height(self)

~~get_z~~ is used to get the height of a ~~Mobject~~.

def def get_depth(self)

~~get_depth~~ is used to get the depth of a ~~Mobject~~
