Overview
Parametric Primitives lets you create precise shapes in Blender with unit-aware inputs (metric & imperial) and per-object controls. Objects remain editable until you Lock them for further modeling.

Included in v1.0
Box, Capsule, Cog, Cylinder, Drop, Pyramid, Sphere, Spring, Star, Tube.

Key Features

• Unit-aware fields: enter values like 25 mm, 1.5 m, 3 in.

• Creation popup: choose World or 3D Cursor placement, set base parameters.

• Per-object panel (N-panel → Parametric): only the active parametric object shows controls.

• Pivot control: Top / Center / Bottom; quick align to 3D Cursor.

• Caps & segments: N-gon / Triangle Fan caps, adjustable segments.

• Lock Parametric: finalizes the mesh and runs Merge by Distance (0.001/adjustable) to weld seams. After locking, parameter updates are ignored (use Undo to revert).

Quickstart

1. Add → Mesh → Parametric → pick a primitive (or Shift+A → Mesh).

2. In the creation popup, set base dimensions (unit-aware).

3. Open N-panel → Parametric and fine-tune per-object settings.

4. When you’re ready to edit topology, enable Lock Parametric to bake & weld.

Notes & Tips

• For exact heights with caps, remember the cap fill can affect perceived height in some views.

• Keep objects unlocked while exploring parameters; Lock only before manual edits.
