◆ A3DCopyAndAdaptBrepModel()
A3DStatus A3DCopyAndAdaptBrepModel | ( | const A3DEntity * | p, |
const A3DCopyAndAdaptBrepModelData * | psSetting, | ||
A3DEntity **const | pp | ||
) |
Copy and adapt B-rep parameters.
The B-rep used by HOOPS Exchange may not be completely compatible with modeling systems that do not support the full range of B-rep as employed by PRC. This function attempts to convert PRC B-rep into a format that is compatible with your system.
In order to use this function, you create a A3DCopyAndAdaptBrepModelData structure and configure it to create a new B-rep model using entities you are able to support. The function can transform predetermined surface types and curves to NURBS. It also can process parametric curves and 3D curves, as well as split periodic parametric surfaces.
Finally, it creates a new B-rep model. After using it, the new model should be deleted.
A3DCopyAndAdaptBrepModel will perform the following steps:
- For each face, the bearing surface and the 3D curves are converted
- Surfaces are reduced in size
- Cross-period UV curves are deleted if necessary
- Faces are split at periodic seams and/or mid-parameter for closed surfaces
- Final UV curves are computed
- A second surface shrink is performed with new UV parameters
- Final 3D curves are computed
- Note
- When the function A3DCopyAndAdaptBrepModel returns an error, you may try to set the parameters m_bSplitFaces and/or m_bForceComputeUV to 'false' and retry the conversion.
- Parameters

Copy and adapt B-rep parameters.
Same as A3DCopyAndAdaptBrepModelData , but return status of each face in error if A3DCopyAndAdaptBrepModelData::m_bContinueOnError is set to true
puiNbErrors return the number of faces in error
paiErrors corresponds to a set of indexes and error codes paiErrors[0] = type the topological element paiErrors[1] = error status paiErrors[2] = number of indexes to find element (connex = 1, shell = 2, face = 3, loop = 4, coedge /edge = 5) paiErrors[3] = first index ... paiErrors[2+paiErrors[2]] = last index
- Parameters
-
[in] p A pointer to the source B-rep entity [in] psSetting The structure that defines which types of B-rep you would like to convert to [out] pp A pointer to the result B-rep entity or entities [out] puiNbErrors Number of elements in error [out] paiErrors Index and error code of each element
- Returns
