Measurix adds measurement, annotation, and technical drawing tools to Blender's 3D Viewport. Create dimensions from mesh selections, add drawing callouts, and export camera-based drawing sheets and tabular reports from your scene.

Features

Measurement

• Linear — straight-line distance between selected points; selected mesh edges can also be measured individually
• Axial — X, Y, and Z distance components
• Angular — angle from three selected vertices, two selected edges, or two selected faces
• Radial — radius or diameter from supported circular edge selections
• Arc Length — length along a selected mesh edge chain
• Area and Perimeter — measurements of selected mesh faces
• Volume — volume of a closed mesh object
• Centerline / Midpoint — midpoint-related dimension and annotation tools
• Auto Measure — chooses a measurement operation based on the current selection
• Continuous and Baseline measurement workflows
• Dimension Chain — create dimensions from selected edges or re-space visible dimensions
• Ordinate dimensions — coordinate dimensions relative to the 3D Cursor
• Object XYZ Bounds — create dimensions for selected mesh object bounds
• Bolt Circle (PCD) — detect circular hole patterns and create a callout

Tracking & Snapping

• Supported measurements can retain vertex or face references and update when referenced geometry changes; behavior depends on the measurement type and source selection
• Snapping is enabled by default, including vertex, edge-midpoint, face-center, and surface snapping
• Snap controls and optional alignment inference are available in the Advanced section

Annotation & GD&T

• Free-text notes and leader lines
• Geometric dimensioning and tolerancing (GD&T) frames
• Datum reference markers
• Surface-finish symbols
• Weld symbols
• Bill of Materials item numbering and balloons
• Optional conversion to Blender Annotation (Grease Pencil) data

Precision & Units

• Metric and imperial units, with optional dual-unit display
• Configurable precision, symmetric and deviation tolerance fields, reference dimensions, and locking
• Parametric set-value tools can change an object's transform when explicitly used
• Custom dimension styles for line and text appearance, arrowheads, and offsets

Documentation & Export

• Camera-based drawing sheets in SVG, PDF, and JPG
• Drawing sheets can include shaded and line-drawing panels, dimensions, title-block information, and optional section views with hatch
• Camera layouts support one sheet per camera or a multi-camera grid; batch camera export is available
• CSV dimension and QC reports, BOM CSV, and hole/feature coordinate CSV tables
• Drawing Readiness checks, reusable drawing presets, dimension history, and an inspector panel

Requirements
