Changes the type of HLR algorithm used for shapes.
If the algo_type is algo, the exact HLR algorithm is used, otherwise the polygonal algorithm is used for defined shapes.
-If no shape is specified through the command arguments, the given HLR algorithm_type is applied to all *AIS_Shape* isntances in the current context, and the command also changes the default HLR algorithm type.
+If no shape is specified through the command arguments, the given HLR algorithm_type is applied to all *AIS_Shape* instances in the current context, and the command also changes the default HLR algorithm type.
**Note** that this command works with instances of *AIS_Shape* or derived classes only, other interactive object types are ignored.

@subsubsection occt_draw_4_310 vsetcolor
Divides surface with C1 criterion and returns the result of splitting of a given surface into surface, which is given as parameter result. If the surface has been divided into segments, then each segment is put to an individual result. This command can correct a given C0 surface at a knot with a given tolerance, if it is impossible, then the given surface is split at that knot. If the last parameter is 1, then 5 knots are added to the given surface, and its surface is split by segments, but this will be performed not for all parametric spaces.

-# split surface with name ‘su’

Custom command implementation has not undergone any changes since the introduction of the plug-in mechanism. The syntax of every command should still be like in the following example.
**Example:**
+~~~~~
static Standard_Integer myadvcurve(Draw_Interpretor& di,
Standard_Integer n,
char** a)
{
...
}
+~~~~~
For examples of existing commands refer to Open CASCADE Technology (e.g. GeomliteTest.cxx).
To become available in the Test Harness the custom command must be registered in it. This should be done as follows.
**Example:**
+~~~~~
void MyPack::CurveCommands(Draw_Interpretor& theCommands)
{
...
__FILE__, myadvcurve, g);
...
}
+~~~~~
