passes. The three <b>Curve Construction</b> menu choices correspond to three
possible types of curves: Polyline, Besier or B-spline (Interpolated).
\n The \b Result of each operation will be a GEOM_Object (edge).
+\n There are two ways to define <b>Points</b>:
+<ul>
+<li> <b>By Selection</b> choice of the points manually in the Object Browser or 3D Viewer.
+<li> <b>Analitical</b> parametric definition of the points through python expressions.
+</ul>
\n <b>TUI Commands:</b>
<ul>
<li><em>geompy.MakePolyline(ListOfShapes,isClosed)</em></li>
<li><em>geompy.MakeBezier(ListOfShapes,isClosed)</em></li>
<li><em>geompy.MakeInterpol(ListOfShapes,isClosed,doReordering)</em></li>
+<li><em>geompy.MakeCurveParametric(XExpr, YExpt, ZExpt, tMin, tMax, tStep, curveType)</em></li>
</ul>
ListOfShape is a list of points through which the curve passes.
If isClosed is True, MakeBezier and MakeInterpol builds a closed edge,
MakePolyline builds a closed wire. If doReordering is True,
MakeInterpol does not follow the order of vertices but searches for the
closest vertex.
+\n XExpr, YExpr, ZExpr python expressions for the X, Y and Z coordinates of the basic points of the curve.
+\n tMin, tMax minimum and maximun values of the parameter \b t.
+\n tStep step of the parameter \b t
+\n curveType type of the curve Polyline, Bezier or Interpolation.
+
+<b>Arguments:</b>
+<ul>
+<li>Name + at least 2 points which will serve as nodes on the curve, or</li>
+<li>Name + 3 string + 3 values (python expressions for the X, Y and Z coordinates, minimum,
+maximum and step values of the parameter)</li>
+</ul>
+
-<b>Arguments:</b> Name + at least 2 points which will serve as nodes
