Key Features for Construction Drawings

2D Drafting

In construction projects, the 2D drawing is the backbone of communication with contractors and authorities. Plan7Architect allows you to:

  • Draw floor plans with exact wall thickness, windows, and doors

  • Add dimensions, room labels, and annotations

  • Use symbols and hatching patterns for materials and construction details

  • Export drawings in standardized formats for professional use

3D Visualization

Alongside technical 2D drawings, you can immediately switch to 3D views. This helps you and others involved in the project to better understand the design. You can:

  • Walk through the building virtually

  • Present structural concepts to clients or partners

  • Export realistic 3D renderings for documentation and presentations

Structural and Technical Tools

Construction drawings go beyond simple layouts. Plan7Architect includes:

  • Roof design with adjustable pitch, overhangs, and materials

  • Foundation planning and floor slab tools

  • Stair and railing design with customizable parameters

  • Wall, floor, and ceiling settings for material layering

Unit Flexibility

Plan7Architect lets you choose between metric and imperial units. Whether you work in meters and centimeters or in feet and inches, the software adapts to your project needs. This makes it practical for international use across different markets.
