free CAD software

Native DWG

The world's most popular file format for technical documentation - DWG - is the nanoCAD Free native file format. Project created and saved as *.dwg file could be easily opened and edited in any CAD application supporting *.dwg.
*nanoCAD Free is an older version of the nanoCAD family, so it does not support the latest versions of the DWG format.

Classic User Interface

Any engineer could easily master nanoCAD Free since everything is in their right places: menu, button icons, panels, command line, and the commands themselves are easily recognizable. This makes nanoCAD Free easy to migrate to since the enterprise needs no time to retrain its engineers.

Fundamental tool set

nanoCAD Free includes all necessary tools for creating and editing 2D/3D objects, texts, tables. Reusable blocks and references to external drawings simplify and speed up the drawing process. Advanced dimensioning features enable you to create any kind of dimension by several means.

Open API

nanoCAD Free has a traditional CAD application programming interface (API) that allows developing independent nanoCAD based applications and additional automation modules.

Comprehensive Tool Set for
2D Drawing and 3D Viewing

nanoCAD Free is the first step to automate your design process. It is free with limited functionality, but enough to support businesses and individuals in their non-commercial projects. To extend the functionality you can always upgrade to nanoCAD Platform and enjoy the full tool set to lead your industry.

Over 450 commands

Access over 450 familiar commands through menus, toolbars, command line, or macros/scripts for an efficiency boost.

Sufficient 2D toolset

Use versatile 2D primitive creation/editing commands and optimized geometry tools with minimal mouse clicks.

Layers at their best

Enhance your document management with layered organization for streamlined creation, editing, and visibility.

Drawings are safe

Safely open DWG files wtih Audit, Recover and Purge commands for error checks, file repairs, and size reduction, even from alternative CAD systems.

Advances document handling

Customize text formatting and styles with advanced annotation tools, including a Multiline Text command and a Search & Replace feature for quick search.

Multiple types of dimensions

Create linear, radial, angular, and arc dimensions, and translate graphics data into a table form. Import and export any table data to automate geometry calculations.

Blocks, Refs and Xrefs

Speed up your design by creating blocks of elements, DWG references, and raster images, and set unique clipping contours for each instance.

Plotting and publishing

Create three-dimensional geometry in model space and prepare the drawing to plot in the paper space with customizable viewports and layouts, scalable plot settings, and features like Batch Plot for multi-sheet file creation, ideal for larger-than-printer outputs.

Enhanced Coordinate System

Enjoy advanced support for Cartesian and Polar coordinates in World and User coordinate systems, with the ability to customize settings individually for each viewport.
