You can also specify anchor points for each guide. These anchor points are intersection points between the guides and the profile's plane or the profile itself, through which the guiding curves will pass. Two points: select anchor points on the profile which will be matched respectively to Guide Curve 1 and 2.If the profile is open, these points are optional and the extremities of the profile are used. Point and direction: select an anchor point on the profile which will be matched onto Guide Curve 1 and an anchor direction.In each sweeping plane, the default x-axis (which corresponds to the given oriented direction) is aligned with the two guide curves, from Guide Curve 1 to Guide Curve 2. If the profile is manually positioned defining anchor points will position the profile between the guides, matching the anchor points with guide intersection points, prior to performing the sweeping operation. 定位点可以控制罗廓线的位置和形状（即按比例缩放），表明轮廓上哪个点和引导线相 对应（当轮廓和引导线不相交时，且轮廓是封闭的） 在轮廓起始点处的spine的垂直面与草绘平面的相交线通过轮廓的两个端点时，不用设 置定位点，否则需要设置定位点或手动定位轮廓线
