CAD Pro Suite

CAD Pro Suite transforms Blender into a professional CAD platform with

engineering-grade precision tools, technical drawing capabilities,

and industry-standard file format support — features typically found

in AutoCAD or Inventor, now directly inside Blender.

Units & Precision System

Work in any unit you need. Full metric support from micrometers to

kilometers and imperial from mils to yards. Enter values naturally —

type "150mm", "6.5in", or "1m" and the addon understands. Three

coordinate input modes: absolute, relative (@50,25,0), and polar

(@100<45). Configurable decimal precision from 0 to 6 places with

automatic unit conversion between all supported types.

CAD-Style Snapping

11 professional snap types for precise object placement:

- Endpoint, Midpoint, Center

- Intersection, Perpendicular, Tangent

- Nearest, Quadrant, Node

- Parallel, Extension

Angle snapping with configurable increments from 5 to 90 degrees.

Visual snap indicators with customizable colors and size for clear

feedback.

Measurement Tools

Measure anything in your scene with engineering accuracy:

- Distance measurement in 2D and 3D

- Angle measurement between points or edges

- Area calculation for selected faces

- Volume calculation for mesh objects

- Perimeter measurement

- Radius and circle fitting

- Bounding box and center of mass computation

All results display in your selected unit system with proper

formatting.

Dimension Tools

Add professional dimensions to your models:

- Linear, Aligned, Angular, Radius, Diameter, Arc Length, Ordinate

- Three style presets — ISO, ASME, DIN

- Configurable arrows — closed filled, open, dot, tick

- Tolerance display with upper and lower bounds

- Custom text and unit suffixes

- Flexible text positioning — above, centered, outside

CAD Primitives

Create geometry with exact specifications:

- Point — place at precise coordinates

- Line — from two points or length and angle

- Rectangle — with exact width and height

- Circle — by radius or diameter

- Arc — multiple creation methods

- Polygon — regular polygons with any number of sides

Technical Drawings

Generate professional technical drawings following international

standards:

- Sheet formats — ISO (A0–A4), ANSI (A–E), GOST, and custom sizes

- Drawing scales — from 10:1 to 1:100

- Title blocks — ISO, GOST, ANSI, DIN templates with automatic field

population

- 11 view types — front, back, left, right, top, bottom, isometric,

section, detail, auxiliary

- Projection methods — first-angle (European) and third-angle

(American)

- Hidden lines — dashed, dotted, and phantom line styles

- Centerlines — automatic generation for symmetrical objects

Annotations & Symbols

Complete annotation toolkit for technical documentation:

- Text annotations and leaders

- Balloons for part numbering

- Surface finish symbols

- Weld symbols

- GD&T (Geometric Dimensioning and Tolerancing) symbols

Geometric Constraints

Apply parametric constraints to maintain design intent:

- Horizontal and Vertical alignment

- Parallel and Perpendicular relationships

- Fixed positions and Coincident points

- Equal lengths and Symmetric placement

- Collinear and Concentric constraints

Import & Export

R2018

- DWG — support via ODA File Converter

- STEP — AP203, AP214, AP242 standards
