Modeling for Blender

Sierpinski Triangle is a Blender add-on from Jonny-B that generates 2D Sierpinski triangles and 3D Sierpinski pyramids. It can stack any mesh into a pyramid, with the generator added from the 3D Viewport's Add > Mesh menu.

SoftViz Pro is a GPU-accelerated viewport overlay for Blender that renders a per-vertex heatmap for Proportional Editing, drawing influence directly onto geometry instead of Blender's native 2D circle.

Target Weld is a Blender modeling add-on for merging vertices and edges interactively. You pick a source and a target in the 3D viewport, and it supports both vertex and edge merge modes.

Three d Cursor Snap is a Blender add-on for moving the 3D cursor with a gizmo-like drag to snap it to a vertex, edge, or face. It works in both Object Mode and Edit Mode.

Vector To 3D is a Blender addon that converts SVG vector files into 3D models. With one-click conversion and adjustable extrusion, bevels, and resolution, it produces 3D icons, banners, logos, and UI/UX mockups.

Analyze Mesh is a lightweight Blender extension that inspects mesh topology, reporting counts of quads, tris, ngons, and edge poles. One click in the side panel returns vertex, edge, and face breakdowns.

Arch Generator is an open-source procedural architecture add-on for Blender that generates customizable arches, pillars, bases, capitals and structural arrays through a fully parametric, non-destructive workflow inspired by historical architectural styles from around the world.

Babel 2.0: Addon brings procedural tear and aging effects to 3D models in Blender, working in real time. It handles mesh deformation and assigns materials to the deformed areas within a procedural workflow.

Backdrop is a Blender add-on by Muzammil-Halimov that adds a quick, adjustable cyclorama with one click. Modelled on the cyclorama in Cinema 4D, it drops a backdrop mesh straight into your scene.

Bezier Curve Fillet Tool is a small Blender add-on that converts sharp bezier corners into rounded edges. It uses a modal operator so results appear in real time as you adjust radius and ratio.

Blendtopo — Topology Optimization brings load-bearing structure generation to Blender, building strong, lightweight, organic lattices inside any mesh from a build space, bearings and loads. Free and open source under GPL-3.0.

Blob Fusion is a Blender add-on for building character and creature base-meshes. It combines Sphere and Round Capsule primitives with organic blending, described by its developer as a mix of ZSpheres and Metaballs.

BrickSculpt is a Blender addon for Bricker that adds a toolset for sculpting, painting, and editing brick sculptures. Draw, Cut, Merge/Split, and Paintbrush tools let you customize brick models after they're generated.

Chain Generator is a Blender add-on for building metal chains from 60 photorealistic parts and 16 materials. Built on geometry nodes, it lets you generate chains at real-world scale with open customization.

Combine is an add-on for Blender that merges objects into one with a single click, removing the need to press different keys to complete the operation. Documentation is included with the add-on.

Cross Section Maker is a Blender add-on that creates a cross-section from a mesh. The cross-section can be projected to the XY plane so it exports cleanly as a DXF file for use in CAD software.

Deform Pro is a Blender addon from AlbertoFX for mesh deformation, offering a Dynamic Lattice that works in Object mode and a Surface Constraint generator that deforms assets with a Laplacian-based method.

Exact Radius is a Blender add-on that turns selected vertex rings into perfect circles of an exact numeric radius. Type the value like you would for Move or Scale, on one ring or many at once.

Handy Surface Detail is a Blender asset pack of over 100 meshes used as surface details. It relies on Blender's internal Tissue addon to populate a target mesh surface and includes a helper script.

Hardflow is a free, open-source hard-surface boolean modeling toolkit for Blender 4.2 and newer. It covers draw-to-cut booleans, precision snapping, direct modeling, curves, decals, and kitbash assets in a single add-on.

Hole Maker is a Blender add-on for cutting holes in a mesh with an exact diameter, depth and position. You pick a vertex as the hole's center and press 'Make Hole(s)' in Edit Mode.

img2cube is a free camera-matching extension for Blender that solves perspective from a photo. Draw lines along parallel edges, click Solve, and the tool recovers focal length and rotation, then places 3D snap points.

Inward Extrude is a Blender addon that cuts into objects destructively, using the object's own geometry to make the cut. Trigger it with Ctrl+Shift+E in edit mode with one or more faces selected.

Ivy It is a Blender add-on from Blender Bits for generating ivy procedurally with geometry nodes. It creates leaves and vines and works with both Cycles and Eevee.
