# Mesh Menu > Asset Transformer Studio Mesh menu reference for repairing and manipulating meshes ![Mesh Menu](/api/media?file=/asset-transformer-studio/2026.5.0/media/STUDIO_Menu_Mesh.jpg) The **Mesh** menu contains the most commonly used mesh data preparation algorithms: | Menu option | Description | | ---------------------------------------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | [**Repair Mesh**](/asset-transformer-studio/2026.5.0/manual/user-interface/menu-bar/mesh-menu/repair-mesh.md) | Automatically repairs selected meshes (tessellated geometries): stitches disconnected edges within the given tolerance, orients faces consistently | | [**Orient Faces**](/asset-transformer-studio/2026.5.0/api/python/algo_functions.md#orientpolygonfaces) | Orients consistently polygons' faces and normals in the same direction by propagating orientation information from one polygon to the other, for the selected meshes.See [About Face and Vertex Normals](/asset-transformer-studio/2026.5.0/manual/data-preparation-fundamentals/about-face-and-vertex-normals.md) | | [**Invert Faces Orientation**](/asset-transformer-studio/2026.5.0/api/python/algo_functions.md#invertpolygonfacesorientation) | Inverts polygons' faces and normals orientation, for the selection. The selection can be either parts, patches or polygons. | | [**Orient Faces From Current View**](/asset-transformer-studio/2026.5.0/api/python/algo_functions.md#orientpolygonfacesfromcamera) | Orient Faces From Current View executes a semi-automatic repair of polygons' face orientation, based on the viewport camera. It uses the camera's position to properly and automatically orient meshes faces toward its direction.**TIP**: Use it step by step around your model until you are satisfied with mesh face orientation | | [**Orient Faces (Advanced)**](/asset-transformer-studio/2026.5.0/api/python/algo_functions.md#orientpolygonfacesadvanced) | Orients all polygon faces in the same direction, automatically and at once, on a full model, using a scattering of cameras to determine faces final orientation | | [**Create Normals**](/asset-transformer-studio/2026.5.0/api/python/algo_functions.md#createnormals) | Creates normals on the polygons of the selectionSee [About Face and Vertex Normals](/asset-transformer-studio/2026.5.0/manual/data-preparation-fundamentals/about-face-and-vertex-normals.md) | | [**Orient Normals**](/asset-transformer-studio/2026.5.0/api/python/algo_functions.md#orientnormals) | Orients consistently clockwise the vertex normals of a mesh in order to correct its smoothingSee [About Face and Vertex Normals](/asset-transformer-studio/2026.5.0/manual/data-preparation-fundamentals/about-face-and-vertex-normals.md) | | [**Delete Normals**](/asset-transformer-studio/2026.5.0/api/python/algo_functions.md#deletenormals) | Deletes normals from a mesh**WARNING**: Deleting normals from a mesh can result in an improper shading (black or faceted)See [About Face and Vertex Normals](/asset-transformer-studio/2026.5.0/manual/data-preparation-fundamentals/about-face-and-vertex-normals.md) | | [**Create Tangents**](/asset-transformer-studio/2026.5.0/api/python/algo_functions.md#createtangents) | Creates tangents on selected meshes, accordingly to their UVs (requires UVs in order to work) | | [**Identify Patches**](/asset-transformer-studio/2026.5.0/api/python/algo_functions.md#identifypatches) | Creates patches boundaries on the selected meshes, based on geometrical information (attributes, edges angle, former CAD information…) | | [**Delete Patches**](/asset-transformer-studio/2026.5.0/api/python/algo_functions.md#deletepatches) | Deletes patches boundaries | | [**Explode Part By Materials**](/asset-transformer-studio/2026.5.0/api/python/algo_functions.md#explodebymaterials) | Creates one Part occurrence by material applied on the patches of the selected parts | | [**Explode Part By Connected Meshes**](/asset-transformer-studio/2026.5.0/api/python/algo_functions.md#explodeconnectedmeshes) | Splits all the [connected meshes](/asset-transformer-studio/2026.5.0/manual/data-preparation-fundamentals/glossary.md#connected-mesh) within a Part into one new Part per connected mesh, for the selected parts | | [**Explode Part By Patches**](/asset-transformer-studio/2026.5.0/api/python/algo_functions.md#explodepatches) | Splits meshes following patch boundaries and creates one single Part occurrence per old patch | | [**Separate Selection in New Part**](/asset-transformer-studio/2026.5.0/api/python/scene_functions.md#separateselection) | Creates a new [part](/asset-transformer-studio/2026.5.0/manual/data-preparation-fundamentals/about-occurrences/occurrence-types.md) out of a selection of submeshes (patches, polygons…) | | [**Create Lines**](/asset-transformer-studio/2026.5.0/api/python/algo_functions.md#createfreeedgesfrompatches) | Creates polylines (made of free edges connected together) out of patches boundaries | | [**Delete Lines**](/asset-transformer-studio/2026.5.0/api/python/algo_functions.md#deletelines) | Deletes polylines (made of free edges connected together)**TIP**: It can be useful to delete lines prior to exporting to FBX files, in order to limit the file size and avoid performance issues in some cases. | | [**Create Textures From Lines**](/asset-transformer-studio/2026.5.0/api/python/algo_functions.md#linetotexture) | Create textures out of coplanar polylines (made of free edges connected together) | | [**Extract Neutral Axis From Pipes**](/asset-transformer-studio/2026.5.0/api/python/algo_functions.md#extractneutralaxis) | Create a polyline (or a group of polylines) out of any swept shape like pipes, wiring, tubing | | [**Create Pipes From Lines**](/asset-transformer-studio/2026.5.0/api/python/algo_functions.md#sweep) | Extrudes a circular section along an underlying polyline (sweep) | | [**Delete Free Vertices**](/asset-transformer-studio/2026.5.0/api/python/algo_functions.md#deletefreevertices) | Deletes all free vertices of a selection of meshes | | [**Remove Z-fighting**](/asset-transformer-studio/2026.5.0/manual/user-interface/menu-bar/mesh-menu/remove-z-fighting.md) | Remove Z-fighting (surfaces overlapping) by slightly shrinking the selected parts' surfaces | | [**Vertex Offset**](/asset-transformer-studio/2026.5.0/manual/user-interface/menu-bar/mesh-menu/vertex-offset.md) | Moves the vertices by offsetting their position along their normal, positively or negatively |
