The curve may be defined as a 2d curve in the parametric space of a surface: a pcurve. The surface on which the edge is built is then kept at the level of the edge. The default tolerance will be associated with this edge. Rules applied to the arguments: For the curve: - The curve must not be a ‘null handle’. - If the curve is a trimmed curve the basis curve is used. For the vertices: - Vertices may be null shapes. When V1 or V2 is null the edge is open in the corresponding direction and the parameter value p1 or p2 must be infinite (remember that Precision::Infinite() defines an infinite value) - The two vertices must be identical if they have the same 3D location. Identical vertices are used in particular when the curve is closed. For the parameters: - The parameters must be in the parametric range of the curve (or the basis curve if the curve is trimmed) If this condition is not satisfied the edge is not built, and the Error function will return BRepAPI_ParameterOutOfRange. - Parameter values must not be equal. If this condition is not satisfied (i.e. if | p1 - p2 | ) the edge is not built, and the Error function will return BRepAPI_LineThroughIdenticPoints. Parameter values are expected to be given in increasing order: C->FirstParameter() - If the parameter values are given in decreasing order the vertices are switched, i.e. the ‘first vertex’ is on the point of parameter p2 and the ‘second vertex’ is on the point of parameter p1. In such a case, to keep the original intent of the construction, the edge will be oriented ‘reversed’. - On a periodic curve the parameter values p1 and p2 are adjusted by adding or subtracting the period to obtain p1 in the parametric range of the curve, and p2] such that [ p1 , where Period is the period of the curve. - A parameter value may be infinite. The edge is open in the corresponding direction. However the corresponding vertex must be a null shape. If this condition is not satisfied the edge is not built, and the Error function will return BRepAPI_PointWithInfiniteParameter. - The distance between the vertex and the point evaluated on the curve with the parameter, must be lower than the precision of the vertex. If this condition is not satisfied the edge is not built, and the Error function will return BRepAPI_DifferentsPointAndParameter. Other edge constructions - The parameter values can be omitted, they will be computed by projecting the vertices on the curve. Note that projection is the only way to evaluate the parameter values of the vertices on the curve: vertices must be given on the curve, i.e. the distance from a vertex to the curve must be less than or equal to the precision of the vertex. If this condition is not satisfied the edge is not built, and the Error function will return BRepAPI_PointProjectionFailed. - 3D points can be given in place of vertices. Vertices will be created from the points (with the default topological precision Precision::Confusion()) Note: - Giving vertices is useful when creating a connected edge. - If the parameter values correspond to the extremities of a closed curve, points must be identical, or at least coincident. If this condition is not satisfied the edge is not built, and the Error function will return BRepAPI_DifferentPointsOnClosedCurve. - The vertices or points can be omitted if the parameter values are given. The points will be computed from the parameters on the curve. The vertices or points and the parameter values can be omitted. The first and last parameters of the curve will then be used. //!

rtype

None* Adds the wire <W> in the face <F> A general method to create a face is to give - a surface S as the support (the geometric domain) of the face, - and a wire W to bound it. The bounds of the face can also be defined by four parameter values umin, umax, vmin, vmax which determine isoparametric limitations on the parametric space of the surface. In this way, a patch is defined. The parameter values are optional. If they are omitted, the natural bounds of the surface are used. A wire is automatically built using the defined bounds. Up to four edges and four vertices are created with this wire (no edge is created when the corresponding parameter value is infinite). Wires can then be added using the function Add to define other restrictions on the face. These restrictions represent holes. More than one wire may be added by this way, provided that the wires do not cross each other and that they define only one area on the surface. (Be careful, however, as this is not checked). Forbidden addition of wires Note that in this schema, the third case is valid if edges of the wire W are declared internal to the face. As a result, these edges are no longer bounds of the face. A default tolerance (Precision::Confusion()) is given to the face, this tolerance may be increased during construction of the face using various algorithms. Rules applied to the arguments For the surface: - The surface must not be a ‘null handle’. - If the surface is a trimmed surface, the basis surface is used. - For the wire: the wire is composed of connected edges, each edge having a parametric curve description in the parametric domain of the surface; in other words, as a pcurve. For the parameters: - The parameter values must be in the parametric range of the surface (or the basis surface, if the surface is trimmed). If this condition is not satisfied, the face is not built, and the Error function will return BRepBuilderAPI_ParametersOutOfRange. - The bounding parameters p1 and p2 are adjusted on a periodic surface in a given parametric direction by adding or subtracting the period to obtain p1 in the parametric range of the surface and such p2, that p2 - p1 <= Period, where Period is the period of the surface in this parametric direction. - A parameter value may be infinite. There will be no edge and no vertex in the corresponding direction.

Add()¶

Further vertices can be added using the Add function. The polygonal wire under construction can be consulted at any time by using the Wire function. Example //an open polygon from four points TopoDS_Wire W = BRepBuilderAPI_MakePolygon(P1,P2,P3,P4); Warning: The process is equivalent to: - initializing an empty polygonal wire, - and adding the given points in sequence. Consequently, be careful when using this function: if the sequence of points p1 - p2 - p1 is found among the arguments of the constructor, you will create a polygonal wire with two consecutive coincident edges.

rtype: None* Adds the point P or the vertex V at the end of the polygonal wire under construction. A vertex is automatically created on the point P. Warning - When P or V is coincident to the previous vertex, no edge is built. The method Added can be used to test for this. Neither P nor V is checked to verify that it is coincident with another vertex than the last one, of the polygonal wire under construction. It is also possible to add vertices on a closed polygon (built for example by using a constructor which declares the polygon closed, or after the use of the Close function). Consequently, be careful using this function: you might create: - a polygonal wire with two consecutive coincident edges, or - a non manifold polygonal wire. - P or V is not checked to verify if it is coincident with another vertex but the last one, of the polygonal wire under construction. It is also possible to add vertices on a closed polygon (built for example by using a constructor which declares the polygon closed, or after the use of the Close function).

class BRepBuilderAPI_Transform(*args)¶

Bases: OCC.Core.BRepBuilderAPI.BRepBuilderAPI_ModifyShape

Constructs a framework for applying the geometric transformation T to a shape. Use the function Perform to define the shape to transform.

param T

type T

gp_Trsf

rtype

None* Creates a transformation from the gp_Trsf <T>, and applies it to the shape <S>. If the transformation is direct and isometric (determinant = 1) and <Copy> = Standard_False, the resulting shape is <S> on which a new location has been set. Otherwise, the transformation is applied on a duplication of <S>.

param S

type S

TopoDS_Shape

param T

type T

gp_Trsf

param Copy

default value is Standard_False

type Copy

bool

rtype

None

Perform()¶

pplies the geometric transformation defined at the time of construction of this framework to the shape S. - If the transformation T is direct and isometric, in other words, if the determinant of the vectorial part of T is equal to 1., and if Copy equals false (the default value), the resulting shape is the same as the original but with a new location assigned to it. - In all other cases, the transformation is applied to a duplicate of S. Use the function Shape to access the result. Note: this framework can be reused to apply the same geometric transformation to other shapes. You only need to specify them by calling the function Perform again.

param S

param Copy
