Create a shape by revolution of the base shape around the axis on the given angle, i.e.

all the space, transfixed by the base shape during its rotation around the axis on the given angle.

Parameters:
theBase Base shape to be rotated.
theAxis Rotation axis.
theAngle Rotation angle in radians.
Returns:
New GEOM_Object, containing the created revolution.

Example

def geompy.MakeRevolution2Ways (   self,
  theBase,
  theAxis,
  theAngle 
)

The Same Revolution but in both ways forward&backward.

def geompy.MakeFilling (   self,
  theShape,
  theMinDeg,
  theMaxDeg,

  theTol3D,
  theNbIter,
  isApprox = 0 
)

Create a filling from the given compound of contours.

Parameters:
theShape the compound of contours
theMinDeg a minimal degree of BSpline surface to create
theMaxDeg a maximal degree of BSpline surface to create
theTol2D a 2d tolerance to be reached
theTol3D a 3d tolerance to be reached
theNbIter a number of iteration of approximation algorithm
isApprox if True, BSpline curves are generated in the process of surface construction. By default it is False, that means the surface is created using Besier curves. The usage of Approximation makes the algorithm work slower, but allows building the surface for rather complex cases
Returns:

Create a shape by extrusion of the profile shape along the path shape.

The path shape can be a wire or a edge. the several profiles can be specified in the several locations of path.

Parameters:
theSeqBases - list of Bases shape to be extruded. Base shape must be shell or face. If number of faces in neighbour sections aren't coincided result solid between such sections will be created using external boundaries of this shells.
