During its creation, the [A3DProjectPointCloudManager](https://docs.techsoft3d.com/exchange/latest/api/A3DSDKTypes_8h.html#_CPPv427A3DProjectPointCloudManager)performs some [NURBS conversion](https://docs.techsoft3d.com/exchange/latest/guide/geometry/convert_brep_to_nurbs.html) of every RepresentationItem present in the input model.

The same result can be reproduced by calling the [AdaptAndReplace](https://docs.techsoft3d.com/exchange/latest/build/group __a3d__ adapt __and__ replace __all__ brep __in__ modelfile.html)or [CopyAndAdapt](https://docs.techsoft3d.com/exchange/latest/api/structA3DCopyAndAdaptBrepModelData.html#a3dcopyandadaptbrepmodeldata)functions, as shown in the BrepAdaptor sample, with the following parameters:

```auto
const A3DUns32 NUM_VALID_SURFACES = 18; // All surfaces are converted
A3DUns32 ACCEPTED_SURFACES[NUM_VALID_SURFACES] = {
	kA3DTypeSurfBlend01,

	kA3DTypeSurfBlend03,

const A3DUns32 NUM_VALID_CURVES = 15; // All curves are converted
