To create a <b>Local Coordinate System</b> in the <b>Main Menu</b> select <b>New Entity - > Basic - > Local Coordinate System</b>
\n There are three algorithms to choose from.

\n Firstly, you can define the values of X, Y, and Z coordinates of origin and the directions of X and Y axes directly in the menu.
\n <b>TUI command:</b> <em>geompy.MakeMarker(OX, OY, OZ, XDX, XDY, XDZ,
YDX, YDY, YDZ)</em>, where OX, OY, OZ are coordinates of the origin of
LCS, XDX, XDY, XDZ is a vector of OX  direction of the LCS and YDX,
YDY, YDZ is a a vector of OY direction of the LCS.
\n <b>Arguments:</b> Name + Coordinates of origin, X axis direction, Y axis direction.

\n Secondly, you can simply select any object in the object browser or
3D viewer, in this case the coordinates of origin and axes direction
of the LCS are calculated automatically basing on the selected object.
\n <b>Arguments:</b> Name + reference object.

\n The last algorithm of LCS construction allows to define the
coordinates of origin by a point and axes directions by a line or a
vector.
\n <b>Arguments:</b> Name + 1 point of origin + X axis direction, Y
axis direction.

Press «OK» or «Apply» button to create an LCS at the location with the
specified coordinates. The new object is shown in the Object Browser
and in 3D viewer.
