老师好，我想问一下，SolidUtil::Create::BodyFromSweep(solid, *extrusionVector, *LinePtr, *ACTIVEMODEL, false, true, false);这一句这两个参数*extrusionVector, *LinePtr，用VS2015 编译时提示错误。其中：*extrusionVector，提示：没有与这些操作数匹配的“”*“”运算符，操作数类型为:*Bentley::DVec3d; 而*LinePtr，提示：不存在用户定义的从"Bentley::ICurvePrimitive" 到 "const Bentley::CurveVector" 的适当转换？
我是参照符老师您之前帮一个学生写的一个扫描成体功能的函数SolidUtil::Create::BodyFromSweep传参的。我的代码如下：
void yourFunctionName(WCharCP unparsed){ ElementId id = 801; ElementHandle myArc(id, ACTIVEMODEL); CurveVectorPtr path = ICurvePathQuery::ElementToCurveVector(myArc); DPoint3d basePt, pts[6],pt1,pt2, tmpPt; basePt.x = 3.2*g_1mu; basePt.y = -0.6*g_1mu; basePt.z = -1.2*g_1mu; pts[0] = basePt; pts[1].x = pts[0].x; pts[1].y = pts[0].y - g_1mu / 2; pts[1].z = pts[0].z; pts[2].x = pts[1].x + g_1mu / 2; pts[2].y = pts[1].y; pts[2].z = pts[0].z; pts[3].x = pts[2].x; pts[3].y = pts[2].y - g_1mu / 2; pts[3].z = pts[0].z; pts[4].x = pts[3].x + g_1mu / 2; pts[4].y = pts[3].y; pts[4].z = pts[0].z; pts[5].x = pts[4].x; pts[5].y = pts[0].y; pts[5].z = pts[0].z; pt1 = pt2 = pts[0]; pt2.z += g_1mu;
CurveVectorPtr SolidProfilePtr = CurveVector::Create(CurveVector::BOUNDARY_TYPE_Outer); bvector<DPoint3d> SolidProfilePts;
//添加截面点到截面中,注意首尾点一定要闭合，首点要加入两次 SolidProfilePts.push_back(pts[0]); SolidProfilePts.push_back(pts[1]); SolidProfilePts.push_back(pts[2]); SolidProfilePts.push_back(pts[3]); SolidProfilePts.push_back(pts[4]); SolidProfilePts.push_back(pts[5]); SolidProfilePts.push_back(pts[0]);
ICurvePrimitivePtr SolidProfileShape = ICurvePrimitive::CreateLineString(&SolidProfilePts.front(), SolidProfilePts.size()); SolidProfilePtr->Add(SolidProfileShape);
DVec3d extrusionVector = DVec3d::FromStartEnd(pt1, pt2);//DVec3d::FromStartEnd 与 DVec3d::FromStartEndNormalize区别
/*---------------------------------------------------------------------------------* * 用pts[0]、pt1、pt2三点创建线串 **--------------------------------------------------------------------------------*/ bvector<DPoint3d> LineStringPts; tmpPt = pts[0]; pts[0] = pt2; pt2 = tmpPt; pt1.x = pts[0].x + g_1mu; pt1.y = pt2.y + g_1mu / 2; LineStringPts.push_back(pts[0]); LineStringPts.push_back(pt1); LineStringPts.push_back(pt2); ICurvePrimitivePtr LinePtr = ICurvePrimitive::CreateLineString(LineStringPts);
ISolidKernelEntityPtr solid; EditElementHandle sweepSolid; SolidUtil::Create::BodyFromSweep(solid, *extrusionVector, *LinePtr, *ACTIVEMODEL, false, true, false); DraftingElementSchema::ToElement(sweepSolid, *solid, nullptr, *ACTIVEMODEL); sweepSolid.AddToModel(); }
我想实现的功能是通过一个面沿着一个线串扫描（或者说拉伸）成一个实体，现在用BodyFromSweep函数，出了点问题，麻烦老师帮忙看一下，谢谢
BodyFromSweep中的profile和path两个参数都要求是CurveVector类型的，而您的这两个参数给的类型都不正确。
下面是我以前写过的一个测试代码供您参考。其中path是一个弧，在我的DGN中其ElemID=809，你可以根据你的具体情况修改这个值。profile是一个圆。
void BodyFromSweepTest(){ ElementId id = 809; ElementHandle myArc(id, ACTIVEMODEL); CurveVectorPtr path = ICurvePathQuery::ElementToCurveVector(myArc);
DPoint3d startPnt, endPnt; DVec3d startTangent, endTangent; path->at(0)->GetStartEnd(startPnt, endPnt, startTangent, endTangent); RotMatrix rMatrix = RotMatrix::From1Vector(startTangent, 2, true);
EditElementHandle myCircle; EllipseHandler::CreateEllipseElement(myCircle, nullptr, startPnt, 100, 100, rMatrix, true, *ACTIVEMODEL); CurveVectorPtr profile = ICurvePathQuery::ElementToCurveVector(myCircle);
ISolidKernelEntityPtr solid; EditElementHandle sweepSolid; SolidUtil::Create::BodyFromSweep(solid, *profile, *path, *ACTIVEMODEL, false, true, false); DraftingElementSchema::ToElement(sweepSolid, *solid, nullptr, *ACTIVEMODEL); sweepSolid.AddToModel();}
老师，您好，ICurvePrimitivePtr 类型的值怎么转换为CurveVector类型的啊？
现在我想把ICurvePrimitivePtr SolidProfileShape 这个变量转换为CurveVector类型的profile;
把ICurvePrimitivePtr LinePtr 转换为CurveVector类型的path;
这个有转换函数吗？
查一下CurveVector类的成员函数，其中的静态函数Create就可以。如下：
