### 5.4.2 Editable Surfaces

An editable surface is an object that is defined via a surface mesh. The surface mesh can be edited via the tools on the Edit panel. If the mesh is closed and composed of triangles, the object can be meshed using the Tetgen tool, available from the Mesh panel. This tool will generate a tetrahedral mesh.
The surface of an editable surface can be modified via the tools on the Edit panel:
• Project curve: projects a curve on the mesh and modifies the mesh locally so that the curve becomes a crease edge of the mesh.
• Partition: Partition the mesh selection.
• Smooth: Smooths the surface mesh.
• Edge collapse: Collapses small edges. This tool can improve the quality of the mesh.
• Decimate: Remesh the triangular meshes using a Centroidal Voronoi Diagram based approach. Decimation is the process of decreasing the number of triangles in the mesh.
• Scale: This option helps in creating a uniform triangular mesh. Scale value specifies the desired reduction in the total number of nodes in the final decimated mesh. For example a 0.4 value of scale will result in the final decimated mesh with 40% of current number of nodes.
• Fix Mesh – Provide options to fix specific problems in mesh
• Remove duplicate elements.
• Remove non-manifold elements.
• Fix winding: This option works only for triangular mesh. This option checks if the nodes of the triangle are in same sequence clockwise/anti-clockwise direction for all the triangular shells.
• Fill all holes: Finds and fills the holes in the triangular mesh by adding new triangular faces.
