Redefining
2D CAD

Drawings are created on a plane.

What humans see and think about is always 2D.

We are rethinking this obvious fact from square one.

Why 2D CAD Now?

Drawings are created on a plane. This fact is so obvious that we rarely think about it. Even with the advent of 3D CAD and BIM/CIM, the starting point of design and the final form that people check and share is, in most cases, 2-dimensional.

Understanding lines. Reading annotations. Recognizing shapes and space. This series of actions takes place on a 2D plane, not in 3D space.

Ultimately,
what humans see and think about is always 2D.

Screens and paper are all flat surfaces.

NijiCAD began by facing this obvious fact once again.

2D CAD Has Become Too Complex

Feature Bloat

2D CAD has evolved over a long time. In many cases, "evolution" has meant "adding more features." As a result, CAD has gradually become a massive and complex entity.

Operational Difficulties

Block shapes can behave dynamically. While this seems convenient at first glance, in practice it is often difficult to manage well. Rather, the potential detrimental effects cannot be ignored.

Compatibility Issues

Many compatible CADs have appeared, but in most cases, they carry over the "same assumptions." Even if the tool changes, the structure of the drawing and how it's handled as 2D CAD doesn't change much.

NijiCAD's Answer

Simple Operation Design

An operation system centered on the command line. If you remember the commands, it's faster than searching for icons. You can focus on thinking without being distracted by operations. It provides clear operation for beginners and hesitation-free operation for experienced users.

Approach to DXF

We don't try to reproduce DXF exactly as is. We import it as simplified figures as much as possible. We don't aim for perfect reproduction. When writing, we export in a form suitable for reuse in AutoCAD or compatible CADs.

Guaranteeing Data Integrity

NijiCAD uses a proprietary drawing data file format. The biggest feature is that it does not reference any external files. This eliminates inconsistencies and missing data due to broken image or resource links. The display and print results will always be consistent, no matter the environment.

Privacy-First Design

For the Windows version, account management is delegated to the Microsoft Store. The operator never handles personal or sensitive information. Even in the Web version, editing data is never sent to a server; all processing is completed within the browser. A design that doesn't hold information. That is one of the answers NijiCAD has chosen.

These philosophies significantly impact operations.
This impact is most clearly manifested in the flow of drawing data.

Data Flow Reflecting Philosophy

DXF is expanded once as disciplined drawing information.
Even after being exported, its organized structure is carried over,
quietly rectifying complex DXF data.

In NijiCAD files, that discipline is maintained from the start.

NijiCAD Drawing Data Flow

Input

Text and dimension styles are unified, and dynamic blocks are redefined as static blocks. Drawings are imported in an organized state, serving as the foundation for subsequent workability.

Drawing

Custom print frames and build settings can be used. Entities are edited while maintaining the same structure as DXF, and drawings are updated while staying in a disciplined state.

Output

Definitions by NijiCAD are carried over. All information, including proprietary definitions, is embedded in the DXF and exported in a reusable form while maintaining reversibility.

Preserving the Opportunity to Use

Pricing will never cause a user to lose the opportunity to use NijiCAD.
This is another design philosophy chosen by NijiCAD.

Free / Pro Lineup

Free is Not a "Lite" Version

Drawing, editing, saving, printing—all the features necessary to complete a drawing are available in the Free version.

Pro is an "Extension"

It is an extension for deeper, more efficient usage. It's not about what you can or can't do, but an option to expand your workflow comfort.

Key Features

These features are not merely a collection of functions.
They are the result of giving direct form to the philosophy NijiCAD upholds.

High Speed Performance

Every single operation manifests directly as a result.
What matters is not processing speed itself, but the perceived speed.
Even during long editing sessions, it doesn't exhaust the operator.

Modern UI

Operations are completed on a single screen.
The UI switches according to operations, bringing only necessary functions to the forefront.
A command line is also included.

Appropriate Compatibility

Incorporate only necessary information and export it in an organized form.
Choose compatibility that works in practice, rather than aiming for perfect reproduction.
