【正文】 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 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 each sweeping plane, the default xaxis (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. 定位點(diǎn)可以控制羅廓線的位置和形狀（即按比例縮放），表明輪廓上哪個點(diǎn)和引導(dǎo)線相對應(yīng)（當(dāng)輪廓和引導(dǎo)線不相交時，且輪廓是封閉的） 在輪廓起始點(diǎn)處的 spine的垂直面與草繪平面的相交線通過輪廓的兩個端點(diǎn)時，不用設(shè)置定位點(diǎn)，否則需要設(shè)置定位點(diǎn)或手動定位輪廓線 Swept Surface 掃描曲面 With reference surface: Select a guide curve, a reference surface, and key in an angle value. The guiding curve must lie pletely on this reference surface, except if the latter is a plane.
