The NodeJS CADViewer Conversion Server (nodejs/cadviewer-conversion-server/) is used in a multitude of CADViewer different implementations: Angular,ReactJS, Laravel, Rails7 , VueJS and as an alternative server in the Apache / PHP installation.

The CADViewer Conversion Server can also be used as a RESTFUL API server for CAD conversions and data extraction, see: CADViewer RESTFUL API

The repository contains a full setup including converters and NodeJS controlling script.

It contains all components to run on either a Windows server or a Linux Server.

NOTE: The CAD converters are of such as size that Git LFS is used, therefore prior to making a git pull, you must first install Git LFS: sudo apt-get install git-lfs and git lfs install .

1: NodeJS script library for controlling CAD Conversions and communication with CADViewer - in its preferred folder structure

2: AutoXchange AX2025 Converter, LinkList2025 Converterand DWGMerge2025 Converter - in their preferred folder structure

3: All structures for file-conversion, rest-API calls, sample drawings, redlines, etc.

4: The converter folder structure contains a larger set of fonts, installed in /cadviewer/converters/autoxchange/fonts/, but a fuller set of fonts can be installed.

Read the sections on installing and handling Fonts in AutoXchange 2024TechDocs and TroubleShooting.

1. The CADViewer_config.json contains all settings for running under Windows and Linux.

2. In the CADViewer_config.json the default settings of the variable autodetect_platform is true and the variable autodetect_location is true. With these settings running app will automatically set up all folder paths for conversions when running on either Windows or Linux.

3. If a user sets autodetect_platform to false and the variable autodetect_location to false, all paths in CADViewer_config.json MUST correspond to the actual server setting.

4. The variable ServerUrl sets the URL of the server with its port, the default setup is http://localhost:3000.

5. When running on Linux, ensure the following:

   5A: Ensure the converter ax2023_L64_12_xx_yy has full chmod 777 permissions (or 755).

   5B: Ensure the folder with temporary files /converters/files has full read and write permissions.

6. Run by using the npm start script or node app from the command line.

7: The CAD converter AutoXchange 2025, - and other converters -, needs to be installed and referenced through the configuration file. The converters typically are in the /cadviewer-conversion-server/converters/ folder structure and comes pre-installed with this package. If using autodetect_ under 2. above, then paths will be set up automatically

9: The CADViewer front-end can be found from our download resources, or installed directly from npm with: npm i cadviewer. Use the following online sample encapsulations from our repository to run CADViewer: for example React CADViewer sample - cadviewer-testapp-react-01, Apache CADViewer - cadviewer-script-library, and many other platform implementations.

9: See Business Extensions to Handlers and CADViewer RESTFUL API to extend the back-end with a customExtension for reading of Blobs/internal datastructure, etc.

NOTE: Make sure the converter version number in CADViwer_config.json match the converters you install, and change any paths settings to correspond to your install folders.

NOTE: If having issues with packages during installation, remove the nodes_modules folder and reinstall using: npm install --legacy-peer-deps

Run: Run by using the npm start script or node app from the command line.

The installation provides a template Dockerfile and docker-compose-yml, which can be updated according to platform. When running under Docker the internal url is 0.0.0.0, and therefore the following fields in the CADViewer_config.json needs to be configured, note that callbackMethod_gatewayUrl is the external url when calling the container, which also needs to be updated appropriately:

"ServerUrl" : "http://0.0.0.0:3000"
"fileLocationUrl" : "http://0.0.0.0:3000/converters/files/"
"callbackMethod_gatewayUrl_flag" : true
"callbackMethod_gatewayUrl" : "http://localhost:3000"

All these modifications are already in the file CADViewer_config-docker.json, so therefore simply copy the Docker template file CADViewer_config-docker.json to CADViewer_config.json , and then execute: docker compose up.

The config file file CADViewer_config-windows-linux.json is a copy of the standard config file CADViewer_config.json.

The user controlled parameters in the configuration file CADViewer_config.json has the following default settings:
