Node.js アプリ内で既存の CAD 図面を読み込み、変更し、保存する方法

const layoutOptions = new cadApi.LayoutOptions({
    layoutName: "Model",
    scaleFactor: 2.0 // Scale the layout by 2x
});

const layoutRequest = new cadApi.PostDrawingSaveAsRequest({
    name: "basic.dxf",
    format: "pdf",
    outPath: "output/basic_scaled.pdf",
    options: layoutOptions
});

// Modify and save the layout with scaling
cad.postDrawingSaveAs(layoutRequest).then(() => {
    console.log("Layout modified and saved as PDF with scaling.");
});

Node.js 環境で AutoCAD DWG を PDF に変換する方法

const cadApi = require("asposecadcloud");

// Initialize the CAD API
const cad = new cadApi.CadApi("Your Client ID", "Your Client Secret");

const conversionRequest = new cadApi.PostDrawingSaveAsRequest({
    name: "sample.dwg",
    format: "pdf",
    outPath: "output/sample.pdf"
});

// Convert the DWG file to PDF
cad.postDrawingSaveAs(conversionRequest).then(() => {
    console.log("DWG file converted to PDF successfully.");
});

Node.js アプリ内で CAD 図面の特定のレイヤーを PNG にエクスポートする方法

const cadApi = require("asposecadcloud");

// Initialize the CAD API
const cad = new cadApi.CadApi("Your Client ID", "Your Client Secret");

const exportRequest = new cadApi.GetDrawingPropertiesRequest({
    name: "sample.dwg",
    folder: "input"
});

// Get CAD drawing properties to identify layers
cad.getDrawingProperties(exportRequest).then((properties) => {
    const layerName = properties.layers[0].layerName;
    
    // Export the first layer to PNG
    const saveAsRequest = new cadApi.PostDrawingSaveAsRequest({
        name: "sample.dwg",
        format: "png",
        outPath: `output/${layerName}.png`,
        options: {
            layerNames: [layerName]
        }
    });

    cad.postDrawingSaveAs(saveAsRequest).then(() => {
        console.log(`Layer '${layerName}' exported as PNG successfully.`);
    });
});
