Grid Modeler sits at rank 31 in the superhive library. It stands out for a grid-based approach that users coming from SketchUp or Fusion 360 may find familiar.
Grid Modeler is a Blender add-on built around a grid-based modeling workflow. You draw shapes on a grid plane to perform Boolean cuts, or stack new mesh geometry on top of existing surfaces. The grid plane can be oriented in any direction, and you can rotate it with the Left and Right arrow keys to build connected geometry.
The toolset covers Boolean cutting, Boolean slicing, creating new faces, shape functions, construction lines, and pipe creation. Grids are precise, and an absolute size mode keeps grid dimensions consistent across faces and objects. The developer notes the workflow shares concepts with CAD software like Google SketchUp and Fusion 360.
Grid Modeler is aimed at speed modeling: quick static objects for games, backgrounds and buildings, items such as swords, shields and armor where consistent scales and angles matter, and hard surface work like sci-fi models, spaceships, robots and weapons.
Grid Modeler is best for speed modeling of hard surface assets: game props, backgrounds, buildings, sci-fi models, spaceships, robots, weapons, and gear like swords, shields and armor where consistent scales and angles are needed.
Grid Modeler is completely free to download and use.
Grid Modeler updated its code for compatibility with Blender 5.0 in version 1.42.0. Earlier updates handled other releases too: a major fix addressed the Python class init changes in Blender 4.4, and support was previously added for Blender 4.0, 3.5, 3.4 and 3.2. Because Blender's API shifts between versions, check the developer's page for the current list of supported releases before installing.
Grid Modeler added touch pad support for MacBook Air in version 1.36.0, so you can pan and zoom in the 3D viewport directly with the touch pad. That makes viewport navigation workable on a MacBook without a separate mouse. Other hardware notes are covered on the developer's page, which is the best place to confirm what your setup needs before you rely on it.
Grid Modeler's Boolean Cut works well along borders. If a cut does not land correctly, the developer suggests aligning the grid to the border edge with Ctrl + Click. When a Boolean fails and cuts nothing at all, adjusting the offset parameter helps reshape the faces of the geometry so the operation can succeed. These tips come from the developer's usage notes and are worth trying before assuming a bug.
Grid Modeler is listed as free in this catalog. Licensing and distribution terms can change over time, so the developer's page is the place to confirm current details before you download. The listing here reflects how the entry is categorized, not a guarantee of future terms. If you plan to use it in a commercial project, verify any conditions directly with the developer first.
