Patch, Spline, and Delete Surfaces
Use the Surfaces: Patch/Spline tool to create patch surfaces or spline surfaces. You can also delete surfaces with this tool.
Patch Surfaces
Create patch surfaces between surface edges or free lines that are not connected.
Spline Surfaces
Create a spline surface using nodes, points, or lines.
Multiple lines, nodes, or points are required. A surface is created using these lines. Lines or nodes can be selected in any order. The correct order is determined when creating the surface.
There is no limit on the number of lines, points, or nodes that you can choose when creating a spline surface. You can create a surface using one line or ten lines (of course, trying to create surfaces using a single straight line would not be useful. To create a surface from one line, the line must be curved). You can select a set of lines, points, or nodes that do not form a closed loop. Disconnected entities are connected with straight lines, and create a spline surface within the boundary formed by the chosen entities and the constructed lines. If the lines selected to create a spline are edges of an adjoining surface, the edge topology is updated to make them shared edges, and considers the curvature of the adjoining surfaces when creating the spline surface.
When creating a spline surface using surface edges, select keep tangency to force the newly-created spline to form a smooth transition with its surrounding surfaces, without feature angles between the new surface and the surrounding ones.
When creating a mesh and surface with nodes, they are automatically stitched to the new surface/mesh by default.
