vector3D input data

Is there a way to input data in to vector3d instance same way like when creating the new vector3D instance (example 1), instead of doing it separately for each axis (example 2).

example 1
ActionScript Code:
[LEFT][COLOR=#000000]var[/COLOR] vec:Vector3D = [COLOR=#000000]new[/COLOR] Vector3DCOLOR=#000000[/COLOR];
[/LEFT]

example 2
ActionScript Code:
[LEFT]vec.[COLOR=#000080]x[/COLOR] = [COLOR=#000080]1[/COLOR];
vec.[COLOR=#000080]y[/COLOR] = [COLOR=#000080]2[/COLOR];
vec.[COLOR=#000080]z[/COLOR] = [COLOR=#000080]3[/COLOR];
[/LEFT]
