Implementation Reference
- main.ts:72-99 (handler)The handler function for the 'load-frag' tool. It checks if the file exists and is a .frag file, loads the fragments using the loadFragments helper, and returns a success message with geometry info.
async ({ filePath }) => { if (!fs.existsSync(filePath) || filePath.endsWith('.ifc')) { return { content: [ { type: 'text', text: `No .frag file found. Please call convert-ifc-to-frag first: Input file path: ${filePath.replace( '.frag', '.ifc' )}; Output file path: ${filePath.replace('.ifc', '.frag')}`, }, ], } } fragments = await loadFragments(filePath) return { content: [ { type: 'text', text: `Loaded fragments from ${filePath}. Loaded ${fragments.getItemsWithGeometry().length} items with geometry: ${JSON.stringify( fetchCategoriesWithGeometry(fragments) )}`, }, ], } } - main.ts:67-71 (schema)Input schema for the 'load-frag' tool defining the filePath parameter.
{ filePath: z .string() .describe('Full path of the file to load with fragments'), }, - main.ts:64-100 (registration)Registration of the 'load-frag' tool using server.tool, including description, schema, and handler.
server.tool( 'load-frag', 'Load a .frag file. Needs file-system server', { filePath: z .string() .describe('Full path of the file to load with fragments'), }, async ({ filePath }) => { if (!fs.existsSync(filePath) || filePath.endsWith('.ifc')) { return { content: [ { type: 'text', text: `No .frag file found. Please call convert-ifc-to-frag first: Input file path: ${filePath.replace( '.frag', '.ifc' )}; Output file path: ${filePath.replace('.ifc', '.frag')}`, }, ], } } fragments = await loadFragments(filePath) return { content: [ { type: 'text', text: `Loaded fragments from ${filePath}. Loaded ${fragments.getItemsWithGeometry().length} items with geometry: ${JSON.stringify( fetchCategoriesWithGeometry(fragments) )}`, }, ], } } ) - fragments.ts:24-29 (helper)Helper function loadFragments that reads the .frag file and creates a SingleThreadedFragmentsModel instance.
export const loadFragments = async (filePath: string) => { const file = await fs.promises.readFile(filePath) const fragments = new FRAGS.SingleThreadedFragmentsModel('model', file) return fragments }
