 <b>Operations - > Transformation - > Scale Transform</b>
 
 \n This operation creates a scaled shape basing on the initial
-shape. For this, you need to define the \b Shape to be scaled, the
-<b>Central Point</b> of scale and the Scale Factor.
-\n The \b Result will be a \b GEOM_Object.

+\n <b>Simple scale</b> scales the entire object (i.e. its dimensions change evenly in all three orthogonal directions). It does not modify the
+geometry of the shape.

+The following parameters and options can be defined in this dialog:
+- <b>Result Name</b>;
+- One or several <b> Objects </b> to be scaled;
+- <b>Central Point</b> (optional) - relatively to which the object is scaled. If the <b>Central Point</b> is not defined, the scaling will be
+performed relatively the origin of the global coordinate system.
+- <b>Scale Factor</b> - the multiplier of axial dimensions. If <b>Scale Factor</b> is negative, the object is mirrored through the <b>Central Point</b>.

+\n <b>Multiple scale</b> allows scaling by different factors along axes. This is a general transformation, which can modify the geometry, for example, a
+circle can be transformed into an ellipse.
