The BMesh object certainly offers greater functionality and capabilities for working with mesh data compared to the standard data set stored in the object’s “data” property. However, some aspects of managing mesh data in a BMesh object aren’t always obvious. For example, consider the rather trivial operation of getting the currently active polygon.
When working with a BMesh object in the Blender Python API, we can get UV points from the vertices of the object itself, just like with the base object.
To export geometry from Blender to a separate OBJ file, we can select File – Export – Wavefront (obj) from the main menu and specify the path to save the .obj file.
When working with geometry in Blender using the Blender Python API, we may need to create a new polygon in the current mesh that lies in the same plane as one of the existing polygons of the mesh.

Let’s say we have two polygons on our mesh in Blender scene, and we want to check if their normals are facing the same direction and flip one of them if they are facing different directions. We can do this using the Blender Python API.
To set the desired volume for multiple audio strips at once in Blender VSE, select them, then in the Properties panel, in the Strip tab, in the Sound section, type the desired number in the Volume field, hold down the Alt key, and press Enter. Holding the Alt key changes the volume for all selected strips; if we don’t hold it down, the volume will only change for the currently active strip. We can also change the volume for all selected audio strips at once using the Blender Python API.

When creating videos in Blender VSE, it’s often necessary to separately create a silent video sequence and only then overlay separately prepared audio tracks onto the edited video stream. However, when adding a video strip to VSE, it is added along with its audio track, with the audio also connected to the video. Separating the audio and video tracks is not difficult, but it takes time. Let’s write a small script that will automatically detach the audio from the video in a strip added to VSE and completely delete the original audio track.
One of the most common tasks when working with mesh geometry using the Python API in Blender is finding the nearest neighboring vertices for a given point. We can find all the nearest vertices within a certain distance from a given vertex using the BMesh and KD-Tree tools.
Using the Mirror modifier greatly simplifies the modeling process on symmetrical objects. To properly optimize a mesh for use with this modifier, we should always delete the part of the mesh that will be mirrored; otherwise, we’ll immediately end up with duplicate geometry, which will lead to problems with further editing and shading. This geometry cleanup process can be optimized with a simple script that automatically removes unnecessary points and adds the modifier to the mesh.

Flatana – Blender 3D extension. Flatana modifies a mesh so that all its polygons become flat—all points of a polygon lie in a single plane.
