Extrude Edges by Offset（Extrude Edges by Offset）
动画教程
Select the coplanar boundary to offset and set the offset distance to generate the face directly. In the process, you can choose whether to flip, whether to delete coplanar lines, and whether to group.

动画教程
Select the line to be stretched, select the initial point and end point after executing the command, then stretch the line to the object and automatically cut the redundant part. In the process, you can choose whether to flip or group.
Extrude Edges by Vector（Extrude Edges by Vector）
动画教程
Select the line to be extruded, select the initial point and the end point after executing the command, and then generate the face along the direction of mouse drag. In the process, you can choose whether to flip or group.
Extrude Edges by Lathe（Extrude Edges by Lathe）
动画教程
Select a curve, polyline or face, select the axis of rotation after executing the command to set the axis of rotation, continue to set the angle of rotation and the number of segments, and confirm to generate. In the process, you can choose whether to flip, whether to delete coplanar lines, whether to smooth the boundary, and whether to group.
Extrude Edges by Rails（Extrude Edges by Rails）
动画教程
After the command is executed, select the start contour, loft path (first rail), loft path (second rail) and end contour to generate the corresponding surface. In the process, you can repair the path direction, whether to flip, whether to turn four sides, and whether to delete the original curve.
Extrude Edges by Edges（Extrude Edges by Edges）
动画教程
Prepare the contour line and loft path line, use the group command in suapp to group the two lines, select the two groups and execute the command to generate the surface. During the process, you can choose whether to unify the direction of the face, whether to turn over the face, whether the model is staggered, whether to delete coplanar lines, whether to subdivide triangular faces, and whether to delete the original group.
Extrude Edges by Face（Extrude Edges by Face）
动画教程
Select the face on the red and green axis as the section, and one or more sidelines as the lofting path, and then the lofting is successful.
Extrude Edges by Rails by Face（Extrude Edges by Rails by Face）
动画教程
Select the face on the red and green axis as the section, select the starting contour line, lofting path (first rail), lofting path (second rail) and ending contour line after executing the command, then select the lofting type, and then confirm to generate the grid structure. In the process, you can choose whether to delete the original curve or not.
Extrude Edges by Loft（Extrude Edges by Loft）
动画教程
After executing the command, select several curves in turn as the section, double-click to confirm the number of segments to generate the surface. During the process, you can choose whether to flip the face, whether to turn the four sides, whether to smooth the edge line, and whether to delete the original curve.
Extrude Edges by Rails to Lattice（Extrude Edges by Rails to Lattice）
动画教程
After executing the command, select the start contour line, loft path (first rail), loft path (second rail), and end contour line in turn, and then select the loft type. For the outline type, select the line or 3D pane, and then confirm to generate the mesh. You can choose whether to delete coplanar lines in the process.
