GnaCAD for Android

GnaCAD — Mobile CAD Overview

GnaCAD is a full-featured CAD application built for Android devices that supports both 2D and 3D drawings. It is engineered to handle very large files by using memory efficiently, and it provides many of the capabilities expected from desktop CAD tools in a mobile package.

File access and team workflows

• Open drawings directly from an SD card or internal storage as well as from Google Drive.
• Add annotations and reply threads on files saved in Google Drive to support team reviews.
• Seamlessly integrate cloud-stored projects into your mobile editing and review processes.

Viewing, editing and performance features

• Edit and inspect both flat (2D) plans and full 3D models with comparable precision to desktop software.
• Efficient memory handling allows loading and navigating large drawings without arbitrary size limits.
• A dedicated property inspector helps you examine and modify object attributes in detail.

Personalization and presentation controls

• Install custom typefaces and shape libraries to match project standards or personal preferences.
• Configure visual styles and lineweight behavior to control how drawings are rendered and printed.
• A flexible settings environment lets you tune the app’s behavior to suit different workflows.
