Earns its place in the superhive library for pairing unit-aware inputs with a lock step that welds seams, letting a primitive stay adjustable until you choose to finalize it.
Parametric Primitives is a Blender add-on that provides smart, adjustable primitives with a simple creation workflow. You reach them through the Shift+A menu under Mesh, where they sit alongside the basic primitives. After creating a shape, its parameters appear in the side menu, opened with the N key, under the Parametric tab, showing only the active object's controls.
Supported fields accept both metric and imperial values, so you can type dimensions in whichever unit system you prefer. Each object carries pivot settings for Top, Bottom, and Center placement, and can align to the 3D Cursor, which the developer notes is useful for aligning to face normals. A Lock Parametric toggle runs a Merge by Distance at a default 0.001 threshold to weld vertices, and locking is recommended before you edit topology so the mesh isn't regenerated by accident.
The initial 1.0 release includes ten primitives: Box, Capsule, Cog, Cylinder (which can act as a Cone), Drop, Pyramid (which can act as a Cake), Sphere, Spring, Star with collapsible sides, and Tube. Documentation is included, and the add-on has been tested on Blender 4.0 and 4.4.1.
Parametric Primitives is best for blender modelers who want adjustable base shapes with unit-aware inputs and per-object pivot control.
Parametric Primitives is completely free to download and use.
Parametric Primitives supports Blender versions 4.0 through 4.4, and the developer notes it was tested on Blender 4.0 (Portable) and 4.4.1. You create the primitives from the Shift+A menu under Mesh, where they appear alongside the basic primitives. Once a primitive exists, its parameters show up in the side menu under the Parametric tab, and only the active object's settings are displayed. If you're running a Blender version inside that supported range, the add-on should behave as described on the developer's page.
Parametric Primitives installs from a downloaded ZIP file. In Blender, open Edit, then Preferences, then Add-ons, choose Install from Disk, and select the ZIP. After that, the Parametric Primitives (All-in-One) entry should be enabled. The add-on is distributed under the GPL license. Once installed, the primitives become available through Shift+A, then Mesh, listed under the basic primitives, so you can start creating adjustable shapes without further setup.
Parametric Primitives exposes its settings through Blender's side menu, opened with the N key, under the Parametric tab, and only the active object's controls appear there. You can switch pivot placement between Top, Bottom, and Center, and align the object to the 3D Cursor, which the developer suggests is handy when aligning to face normals. Note that with capped shapes, cap fill geometry may affect the perceived height in some view modes, so exact heights can look different depending on how you're viewing them.
Parametric Primitives includes a Lock Parametric toggle that runs a Merge by Distance with a default threshold of 0.001 to weld vertices. The developer recommends locking an object before you plan to modify its topology, so you don't accidentally regenerate the mesh. The toggle is one of the per-object controls the add-on exposes under the Parametric tab in Blender's side menu, opened with the N key. Only the active object's settings appear there, so you adjust the lock on the shape you're currently working on.
Parametric Primitives is listed as free here in the catalog. For current licensing terms, check the developer's page, since the add-on itself is distributed under the GPL license. The initial release, version 1.0, ships with ten primitives including Box, Capsule, Cog, Cylinder, Drop, Pyramid, Sphere, Spring, Star, and Tube, along with included documentation. Pricing and availability can change over time, so the developer's page is the best place to confirm the latest details.
