Introduction

CAD Exchanger Web Toolkit is set of JavaScript libraries to create, explore, analyze and visualize CAD models.

The Toolkit is used as an underlying engine by CAD Exchanger Cloud Solution (cloud.cadexchanger.com). CAD Exchanger Web Toolkit can also be used by software vendors to integrate into their custom applications to support CAD formats of interest.

Toolkit libraries

The Toolkit consists of three libraries:

1. Core - contains core classes required for CAD Exchanger data model. Depends on pako.js (v1.10.0) library.
2. Full - contains core and visualization classes. Depends on pako.js (v1.10.0) and three.js (r105) libraries.
3. Three - contains additional classes allowed convert CAD Exchanger data model into three.js entities. Depends on core and three.js (r105) libraries.

Core and Full libraries are provided in two forms:

1. Bundled - library with injected external dependencies. There are no additional libraries required.

   <script src="/build/prod/assets/cadex.core.bundle.js"></script>

2. Minified - library without injected external dependencies. Requires dependent libraries to be loaded beforehand.

   <script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/pako.min.js"></script>
   <script src="https://cdn.jsdelivr.net/npm/[email protected]/build/three.min.js"></script>
   <script src="/build/prod/assets/cadex.min.js"></script>

Three library is provided in minified version only.

Examples

Examples must be run in Node, as they need access to local files via HTTP request.

npm run examples

Then open http://localhost:8000/examples/ url in the browser. Pre-prepared model can be found in the examples/models/native folder.

The most recent examples are also available online.

Custom models

Before a custom model can be visualized it should be converted to CAD Exchanger's CDXFB format specifically adapted for browser.

There are two ways to perform this conversion:

• Using CAD Exchanger Cloud API
• Using CAD Exchanger CLI

  • Use cdxfb file extension for export

    ExchangerConv.exe -i myfile.jt -e myfile.cdxfb -s settings.ini

    This command creates a folder named myfile.cdxfb containing all the model's data.

    Note: CAD Exchanger uses random GUIDs for sub-file name generation, so different runs of this conversion command will produce different sets of files.

  • Model can be exported only partially to reduce its size or skip unneeded data. This can be achieved by specifying which data needs to be exported in a settings file. For more information about CLI settings please refer to CLI settings file.

  • Export to CDXFB requires a separate license. Please contact [email protected] to request an evaluation.
