Hi, Leidy If you want to create a point by giving the coordinates of it, it certainly can be created. Call GeometryModifyTool::make_RefVertex. There's no method in CGM to find the Vertex by location, this seems to be a graphics call. For example, if you have graphics layer on top of CGM, you should be able to draw a rectangle box and all ref-entities within this box will be selectable.

Three coplanar, non-collinear curves that not all intersect at the same point can define four possible circles. Any three such lines must form a triangle. One possible circle seems to be the one you are considering: the inner circle of the triangle. The other three circles are outside the triangle, tangent to one of the lines on the triangle boundary and tangent to the other two lines at a point outside of the triangle. Given that the input to this function is a set of *bounded* curves, you should choose the circle for which all tangent points are within the bounded region of each curve, rather than those that are within the portion of the lines that form the triangle. - jason > Modified: cgm/trunk/geom/OCC/OCCModifyEngine.cpp > =================================================================== > --- cgm/trunk/geom/OCC/OCCModifyEngine.cpp 2008-12-22 19:17:36 UTC (rev 2493) > +++ cgm/trunk/geom/OCC/OCCModifyEngine.cpp 2008-12-23 17:06:19 UTC (rev 2494) > @@ -4840,20 +4840,47 @@ > } //0.check that non of the curves are parallel of each other. > - double u11, u12, u21, u22, u31, u32; > - occ_crv1->get_param_range(u11, u12); > - occ_crv2->get_param_range(u21, u22); > - occ_crv3->get_param_range(u31, u32); > - - CubitVector pt1, pt2, pt3; > - occ_crv1->position_from_u(u11, pt1); > - occ_crv2->position_from_u(u21, pt2); > - occ_crv3->position_from_u(u31, pt3); > + DLIList<CubitVector*> intscts; > + CubitVector vt1, vt2, vt3; > + CubitBoolean none = CUBIT_FALSE; > + OCCQueryEngine::instance()->get_intersections(curve1, curve2, intscts,none,none); > + vt1 = *intscts.get(); > + intscts.clean_out(); > + OCCQueryEngine::instance()->get_intersections(curve2,curve3, intscts,none,none); > + vt2 = *intscts.get(); > + intscts.clean_out(); > + OCCQueryEngine::instance()->get_intersections(curve3, curve1, intscts,none,none); > + vt3 = *intscts.get(); > + double u, u11, u12, u21, u22, u31, u32; > + u12 = occ_crv1->u_from_position(vt1); > + u11 = occ_crv1->u_from_position(vt3); > + if(u12 < u11) > + { > + u = u12; > + u12 = u11; > + u11 = u; > + } > + u22 = occ_crv2->u_from_position(vt1); > + u21 = occ_crv2->u_from_position(vt2); > + if(u22 < u21) > + { > + u = u22; > + u22 = u21; > + u21 = u; > + } + u32 = occ_crv3->u_from_position(vt2); > + u31 = occ_crv3->u_from_position(vt3); > + if(u32 < u31) > + { > + u = u32; > + u32 = u31; > + u31 = u; > + } > CubitVector tangent1, tangent2, tangent3; > - occ_crv1->get_tangent(pt1, tangent1); > - occ_crv2->get_tangent(pt2, tangent2); > - occ_crv3->get_tangent(pt3, tangent3); + occ_crv1->get_tangent(vt1, tangent1); > + occ_crv2->get_tangent(vt2, tangent2); > + occ_crv3->get_tangent(vt3, tangent3); CubitVector normal1 = tangent1 * tangent2; > CubitVector normal2 = tangent2 * tangent3; > @@ -4889,18 +4916,6 @@ > //2.create curves to bisection each of the angle passing through the > // vertices of the triangle > - DLIList<CubitVector*> intscts; > - CubitVector vt1, vt2, vt3; > - OCCQueryEngine::instance()->get_intersections(curve1, curve2, intscts,0,0); > - vt1 = *intscts.get(); - intscts.clean_out(); > - OCCQueryEngine::instance()->get_intersections(curve2,curve3, intscts,0,0); > - vt2 = *intscts.get(); > - intscts.clean_out(); > - OCCQueryEngine::instance()->get_intersections(curve3, curve1, intscts,0,0); > - vt3 = *intscts.get(); > - //Create 6 curves, find 3 of them which have intersection points inside > - // the third curve > CubitVector t_curve11 = vectorRotate(angle1/2.0, normal1, tangent1); t_curve11.normalize(); > @@ -4934,10 +4949,9 @@ > //3. find the intersection of each of the bisection curve with the third curve > CubitVector int_pt1, int_pt2, int_pt3; > intscts.clean_out(); > - CubitBoolean none = CUBIT_FALSE; > OCCQueryEngine::instance()->get_intersections(curve3, vt1, p11, intscts,none,none); > CubitVector int_pt = *intscts.pop(); - double u = occ_crv3->u_from_position (int_pt); > + u = occ_crv3->u_from_position (int_pt); > if(u >= u31-tol && u <= u32+tol) //found intersection point > int_pt1 = int_pt; > else >

Three coplanar, non-collinear curves that not all intersect at the same point can define four possible circles. Any three such lines must form a triangle. One possible circle seems to be the one you are considering: the inner circle of the triangle. The other three circles are outside the triangle, tangent to one of the lines on the triangle boundary and tangent to the other two lines at a point outside of the triangle. Given that the input to this function is a set of *bounded* curves, you should choose the circle for which all tangent points are within the bounded region of each curve, rather than those that are within the portion of the lines that form the triangle. - jason > Modified: cgm/trunk/geom/OCC/OCCModifyEngine.cpp > =================================================================== > --- cgm/trunk/geom/OCC/OCCModifyEngine.cpp 2008-12-22 19:17:36 UTC (rev 2493) > +++ cgm/trunk/geom/OCC/OCCModifyEngine.cpp 2008-12-23 17:06:19 UTC (rev 2494) > @@ -4840,20 +4840,47 @@ > } > > //0.check that non of the curves are parallel of each other. > - double u11, u12, u21, u22, u31, u32; > - occ_crv1->get_param_range(u11, u12); > - occ_crv2->get_param_range(u21, u22); > - occ_crv3->get_param_range(u31, u32); > - > - CubitVector pt1, pt2, pt3; > - occ_crv1->position_from_u(u11, pt1); > - occ_crv2->position_from_u(u21, pt2); > - occ_crv3->position_from_u(u31, pt3); > + DLIList<CubitVector*> intscts; > + CubitVector vt1, vt2, vt3; > + CubitBoolean none = CUBIT_FALSE; > + OCCQueryEngine::instance()->get_intersections(curve1, curve2, intscts,none,none); > + vt1 = *intscts.get(); > + intscts.clean_out(); > + OCCQueryEngine::instance()->get_intersections(curve2,curve3, intscts,none,none); > + vt2 = *intscts.get(); > + intscts.clean_out(); > + OCCQueryEngine::instance()->get_intersections(curve3, curve1, intscts,none,none); > + vt3 = *intscts.get(); > > + double u, u11, u12, u21, u22, u31, u32; > + u12 = occ_crv1->u_from_position(vt1); > + u11 = occ_crv1->u_from_position(vt3); > + if(u12 < u11) > + { > + u = u12; > + u12 = u11; > + u11 = u; > + } > + u22 = occ_crv2->u_from_position(vt1); > + u21 = occ_crv2->u_from_position(vt2); > + if(u22 < u21) > + { > + u = u22; > + u22 = u21; > + u21 = u; > + } > + u32 = occ_crv3->u_from_position(vt2); > + u31 = occ_crv3->u_from_position(vt3); > + if(u32 < u31) > + { > + u = u32; > + u32 = u31; > + u31 = u; > + } > CubitVector tangent1, tangent2, tangent3; > - occ_crv1->get_tangent(pt1, tangent1); > - occ_crv2->get_tangent(pt2, tangent2); > - occ_crv3->get_tangent(pt3, tangent3); > + occ_crv1->get_tangent(vt1, tangent1); > + occ_crv2->get_tangent(vt2, tangent2); > + occ_crv3->get_tangent(vt3, tangent3); > > CubitVector normal1 = tangent1 * tangent2; > CubitVector normal2 = tangent2 * tangent3; > @@ -4889,18 +4916,6 @@ > > //2.create curves to bisection each of the angle passing through the > // vertices of the triangle > - DLIList<CubitVector*> intscts; > - CubitVector vt1, vt2, vt3; > - OCCQueryEngine::instance()->get_intersections(curve1, curve2, intscts,0,0); > - vt1 = *intscts.get(); > - intscts.clean_out(); > - OCCQueryEngine::instance()->get_intersections(curve2,curve3, intscts,0,0); > - vt2 = *intscts.get(); > - intscts.clean_out(); > - OCCQueryEngine::instance()->get_intersections(curve3, curve1, intscts,0,0); > - vt3 = *intscts.get(); > - //Create 6 curves, find 3 of them which have intersection points inside > - // the third curve > CubitVector t_curve11 = > vectorRotate(angle1/2.0, normal1, tangent1); > t_curve11.normalize(); > @@ -4934,10 +4949,9 @@ > //3. find the intersection of each of the bisection curve with the third curve > CubitVector int_pt1, int_pt2, int_pt3; > intscts.clean_out(); > - CubitBoolean none = CUBIT_FALSE; > OCCQueryEngine::instance()->get_intersections(curve3, vt1, p11, intscts,none,none); > CubitVector int_pt = *intscts.pop(); > - double u = occ_crv3->u_from_position (int_pt); > + u = occ_crv3->u_from_position (int_pt); > if(u >= u31-tol && u <= u32+tol) //found intersection point > int_pt1 = int_pt; > else >
