Feature Based Design exercise H:\ota-training\kddat\log1 多重曲線的曲面合成 exercise Global Filleting exercise *Surface Creation - Fillet Flange - create flanges on fillet surfaces. tangentially to the selected patches -The edges of the patches are the spine curve. -The fillet surface can be trimmed at or extrapolated up to the starting edge. *Surface Creation - Ruled Surface -A curve is translated along a vector by which a translation surface is created. 用一條curve做直直長出的patch *Surface Modification - Point - surface (patch cluster) are modified by using a reference patch which is manipulated instead of the surface. - curves and raw data, can be modified with this function. *Surface Modification - Control Point - a surface (patch cluster) are modified by using a reference patch which is manipulated instead of the surface. - curves and raw data, can be modified with this function. 指定一個面當基準來拉動整個model *Surface Modification - Matching (Multiple Matching) - a patch transition (matching) for three or four Bezier patches may be created by one step. - K- and T-transitions , connections of part edges can also be realized with function. 調整有共點之一組面間的連續性 *Surface Modification - Refit Surface - a patch cluster may be mapped onto digitized data. -The patch cluster structure remains unchanged 將數個patches對點側資料做逼近 *Surface Modification - Feature Design -Using this function you may draw and adapt geometry elements to surfaces. 將舊設計套入新設計中 *Surface Modification - Global Fillet - create with one step fillet surfaces at multiple patch clusters,  including at surfaces intersecting each other. 對整個Model做全域性的倒R處理 *Surface Modification - Crowning - the surface shape is modified in a point directly by the specified value (see figure below). - in tool manufacturing to compensate the spring-back of the sheet metal for the whole geometry. *Surface Modification - Convert - convert surfaces from NURBS to Bezier represe
