Fine-Tuning Mesh Selection and Editing Selecting specific faces, edges, and vertices on a mesh is key to fine-tuning edits in Blender. The selection tools allow isolating particular mesh elements for precision modifications. Common selection methods include box select for grabbing many contiguous faces, border select for picking edges on mesh boundaries, and lasso select for…

Understanding Global Transforms in Blender The global transform of an object in Blender refers to its overall position, rotation, and scale in the 3D scene. This is determined by the object’s own transforms, as well as transforms of parent objects and modifiers. Understanding how these factors combine is key for diagnosing unexpected behavior. When you…

Understanding Proportional Editing Proportional editing is a transform tool in Blender that allows users to edit mesh elements while smoothly propagating, or continuing, that transformation to surrounding geometry. It can be thought of as moving mesh areas in a proportional, or weighted, falloff based on their distance from the selected elements. When proportional editing is…

What Causes Unintended Whole-Mesh Transformations There are several common causes of unintentionally transforming all meshes in a Blender scene when only meaning to transform a single object or part. Understanding what leads to these unintended whole-mesh transformations is key to avoiding frustration. Forgetting to Set the Pivot Point One frequent source of accidental scene-wide transformations…

What is Non-Manifold Geometry? Non-manifold geometry refers to meshes in Blender that violate the topological rules for manifold shapes. A manifold mesh has clearly defined inside and outside surfaces with consistent face normals. Non-manifold areas occur where these rules break down, such as on borders between multiple surfaces or with overlapping elements. Common examples of…

Identifying Non-Manifold Geometry in Blender Models Non-manifold geometry refers to areas of a 3D model where the mesh has irregularities that make it incompatible for 3D printing or other applications. These irregularities include edges that are connected to more or less than two faces, vertices connected to faces with inconsistent normal directions, and overlapping geometry….

What is Non-Manifold Geometry? Non-manifold geometry in Blender refers to meshes that violate the topological rules for manifold meshes. A manifold mesh has well-defined volume inside the surface and no anomalies in the connectivity of edges and faces. Non-manifold geometry lacks this clean topology and includes issues like duplicated vertices, unconnected elements, and self-intersecting surfaces….

Non-manifold geometry in Blender refers to meshes that violate the mathematical definition of a 2-manifold surface. Such meshes contain irregularities like open edges, duplicated elements, and self-intersections that can cause issues when modelling, sculpting, rendering, and more. Defining and identifying non-manifold geometry is the first step towards working with or fixing these meshes in Blender….

Understanding Non-Manifold Geometry Non-manifold geometry refers to parts of a 3D model that violate the mathematical definition of a manifold. A manifold is a topological space where every point has a neighborhood that resembles Euclidean space. In simpler terms, a proper manifold has well-defined inside and outside surfaces. Non-manifolds, on the other hand, contain irregularities…
