画了一个多段线，用什么函数能旋转成一个曲面....

qhaha

用polyline画了一个多段线，如果用函数沿着一个轴旋转成一个曲面 用的什么函数 多谢了

创建AcDb3dSliid,然后用它下面的方法旋转成曲面

AcDb3dSolid::createExtrudedSolid (AcDbEntity*, AcGeVector3d&, AcDbSweepOptions&)

Creates a solid by sweeping a planar curve, region, or planar surface in the direction of the given vector using a distance equal to the length of the vector. Optional parameters, such as draft angle, may be set through the sweepOptions parameter. Returns Acad::eOk upon successful creation, Acad::eInvalidInput if given data fails validation, or Acad::eFail if the solid cannot be created.

AcDb3dSolid::createSweptSolid (AcDbEntity*, AcDbEntity*, AcDbSweepOptions&)

Creates a swept solid by sweeping a curve, region, or planar surface (pSweepEnt) along the path pPathEnt. Optional parameters, such as draft angle, may be set through the sweepOptions paramater. The default alignment for AcDbSweepOptions is kNoAlignment. You must set the alignment to kAlignSweepEntityToPath before calling this function. Returns Acad::eOk upon successful creation. Returns Acad::eInvalidInput if given data fails validation. Returns Acad::eFail if solid cannot be created.

[img][/img][img][/img] AcDb3dSolid::createLoftedSolid (AcArray<AcDbEntity*>&, AcArray<AcDbEntity*>&, AcDbEntity*, AcDbLoftOptions&)

Creates a lofted solid from the given curves using the specified options. Returns Acad::eOk upon successful creation, Acad::eInvalidInput if given data fails validation, or Acad::eFail if the solid cannot be created.

等等

十分谢谢您的回答，我试了一下您说的函数，这个生成的是个实体，我想生成的是一个面，后来我找到了用acdbrevolvedsurface这个是可以的
