<p class="whs2">You can enter the values of X, Y, and Z coordinates
 of origin in the corresponding fields of the dialog box, or select a point
 in the object browser or 3D viewer, in this case the coordinates of origin
 are automatically filled in with the coordinates of the selected point.

<p class="whs2">The user then specifies components of X and
 Y axes direction.</p>

<p class="whs2">Preview of the new LCS (small trihedron located
 and oriented according to parameters of LCS) is displayed in the 3D viewer
 and updated as soon as the user modifies some parameter. </p>

<p class="whs2">Then the user presses <20>OK<4F> or <20>Apply<6C> button
 to create an LCS at the location with the specified coordinates. The new
