CIMDraw is a simple web application to view IEC CIM files (ENTSO-E CGMES profile, node-breaker representation). Basic editing is also possible.
Local usage and development
Browsers enforce strict security permissions to prevent you from reading files out of the local file system. To use or develop CIMDraw locally, you must run a local web server rather than using file://…. Node’s http-server is recommended. To install:
npm install -g http-server
This will start the server on http://localhost:8080 from the current working directory.
