Unleash Your CAD Automation Potential with CadSDK

Are you looking to programmatically generate or modify CAD drawings without the complexities of traditional CAD software APIs? CadSDK offers a powerful and streamlined solution. It's a robust .NET 8 library designed to simplify the creation and manipulation of CAD drawing sessions, allowing you to define complex geometries and entities using familiar C# objects, which are then seamlessly converted to standard CAD formats like DWG and DXF.

At its core, CadSDK operates on a client-server architecture. Your application, using the lightweight CadSDK library, constructs a `DrawingSession` object in C#. This session, containing all your defined layers, blocks, and geometric elements, is then serialized into a clean JSON format. This JSON payload is sent to the `CadSDK.WebApp` service, which acts as the conversion engine, leveraging powerful licensed components to perform the actual CAD file generation. This separation ensures that your client-side applications remain lean and platform-agnostic, focusing purely on design logic.

Getting started with CadSDK is straightforward. Once you have your API key, you can instantiate a `DrawingSession`, add various CAD elements like lines, circles, text, or even complex blocks, and then export your design. This programmatic approach opens up a world of possibilities for automating repetitive design tasks, integrating CAD capabilities into web applications, or generating custom reports and visualizations.

Here’s a simple C# example demonstrating how to create a drawing with a single line and export it:

using CadSDK.Elements;
using CadSDK.Enums;
using System.Numerics;

public class SimpleCadExample
{
    public static async Task CreateAndExportLine(string apiKey)
    {
        // 1. Create a new DrawingSession
        var session = new DrawingSession
        {
            ExportFormat = ExportFormat.DWG,
            CadVersion = CadVersion.Cad2018 // Target AutoCAD 2018 format
        };

        // 2. Define a layer for your elements
        var myLayer = new Layer { Name = "MyFirstLayer", ColorARGB = AciColors.Blue };
        session.AddLayer(myLayer);

        // 3. Create a Line element
        var line = new Line(
            startPoint: new Vector3(0, 0, 0),
            endPoint: new Vector3(100, 100, 0))
        {
            LayerName = myLayer.Name,
            ColorMethod = PropertyMethod.ByLayer // Use the layer's color
        };

        // 4. Add the line to the drawing session
        session.AddElement(line);

        // 5. Export and save the drawing
        string outputPath = "MyFirstDrawing.dwg";
        bool success = await session.ExportAndSaveAsync(apiKey, outputPath);

        if (success)
        {
            Console.WriteLine($"Successfully exported drawing to {outputPath}");
        }
        else
        {
            Console.WriteLine("Failed to export drawing.");
        }
    }
}

CadSDK empowers developers to integrate robust CAD functionalities into their applications with ease, abstracting away the complexities of underlying CAD engines. Whether you're building a web-based configurator, an automated reporting tool, or a custom design application, CadSDK provides the programmatic control you need to bring your ideas to life.
