• NewLabelDot3D( <coordinate>, <"name">, <direction> [, DrawDot, distance] ).
• Description: the argument <coordinate> is a space point, that can be in the form $M\left(x,y,z\right)$ or $\left[x+iy,z\right]$. The macro create a global variable called <"name"> with the value <coordinate>. It also create a graphical element displaying the variable name besides the point <coordinate>. The direction (in the screen plane) can be "N" for north, "NO" for north-west, "SO" for south-west, "SE" for south-east...etc, or a list in the form [longueur, direction] where direction is a complex, In that second case, the optional parameter <distance> is ignored. The point is also displayed when <DrawDot> is $1$ (default value) and the <distance> (in cm) between the point and the text can be redefined (0.25cm by default). The graphical element calls the macro LabelDot.
• That macro is associated to a button in the toolbar: Supplément 3D (more 3D tools).
