A deterministic tracer (no AI). Free with every feature: unlimited colours, every format, 2 exports […]

Decimify: Free SketchUp Polygon Reducer & Mesh Optimizer

Decimify is a free SketchUp polygon reducer that imports external models in GLB/STL format and reduces the face count of SketchUp geometry. SketchUp 2020 added native GLTF/GLB import — but it has no built-in decimator. When the imported object has a dense mesh, SketchUp’s Soften/Smooth Edges and Hidden Geometry only change how faces are displayed, […]

Decimify Online: Free 3D Mesh Simplifier — No Install, Browser

Polygon reduction is the problem 3D workflows hit every day — online mesh simplifiers fill this gap without requiring any install – game engines need a triangle budget, web 3D and AR load faster with fewer polygons, and slicers choke on dense scans. Decimify reduces polygon count in your browser — a free online 3D […]

BevelUp: Free Round Corner & Fillet Plugin for SketchUp

SketchUp’s 3D modeler still has no fillet or chamfer command for rounding the edges of a solid, so softening a corner usually means fighting with Follow Me or buying a paid extension. (SketchUp 2026 did add Fillet and Chamfer tools — but only inside LayOut, for 2D vector linework, not for 3D geometry.) BevelUp fixes […]

Top 5 Blender Addons: Image to Mesh via Tracing (2026)

TracePen image to mesh Blender addon panel

Turning a PNG or JPG into Blender mesh geometry no longer needs an Illustrator or Inkscape round-trip — these five image-to-mesh addons trace it directly inside Blender. They all use contour tracing, not AI depth reconstruction, so you get clean, editable per-colour geometry rather than a noisy scanned blob. First, the part that decides your […]

3 Best SketchUp Mesh Simplification Plugins — #3 Is Free

SketchUp has no built-in mesh simplification or decimation tool — this is a deliberate design decision, not an oversight. SketchUp was designed for architects drawing from scratch, not for processing meshes imported from game engines or Megascans. When you import a file from 3D Warehouse, receive an FBX from a client, or export from Revit, […]

Best Image to Vector Tool: Illustrator vs CorelDRAW vs Vector Magic vs TracePen

Disclosure up front: I’m the author of TracePen, one of the tools in this comparison. I wanted to see honestly where it stands in this image-to-vector tool comparison against Illustrator, CorelDRAW, and Vector Magic — so I ran the same photo through all four and I’m posting the outputs here. Judge for yourselves; I’ll flag […]
