If we need to quickly rename the desired UV Layer for all selected objects in Blender, we can use a simple Python API script to do this in a one button press.

If a particle system uses a collection with different meshes as its source, we can use the Blender Python API to determine which object is the source of each particle.
Just like the common mesh data structure, the “bmesh” object contains the concept of the currently “active” vertex. We can find out which vertex is considered as active in the bmesh, and also assign the active vertex in the bmesh using the Blender Python API.
In general, gizmos looks like arrows and circles on a 3D object with which we can move, rotate and scale the mesh. However, in Blender, the gizmo object is more versatile and can be used to suit our needs in different workspaces. For example, we can create a gizmo to adjust the start and end points of the timeline.
We can enable or disable a collection that contains a specific object using the Blender Python API with a simple script. For example, let’s turn off the collection in which the currently selected object is.
We can quickly activate all collections in Blender on the current view layer – enable the “checkbox”, “eye” and “monitor” icons for all of them, using a simple script.
For different work directions in Blender, separate startup configurations are organized – sets of basic settings for scene parameters, rendering and user interface. Each configuration is stored in a separate file and is loaded from it when the user opens Blender or executes the “File – New” command from the main menu.
Workspaces in Blender are saved sets of work areas (windows of the desired type). Typically, switching between them is done by clicking on the tab with the name of the workspace at the top of the Blender UI. We can also switch between workspaces using the Blender Python API.
To mirror an object along X, Y or Z axis in Blender the “Miror” operator is usually used. For example, to mirror an object along the global X axis, in the 3D viewport window menu we need to select: Object – Miror – X Global. Or we can do it simpler just applying a scale of -1 to the object along the desired axis: s – x – -1. However, if there are custom normals on the object, they are not recalculated, which subsequently causes the appearance of various artifacts.

By processing mesh geometry with a bmesh object, we can easily find common edges between two vertices, using the list of edges linked to current vertex.
