AutoCAD Code Pack is a powerful library that helps you to develop AutoCAD plugins using the AutoCAD .NET API. It re-encapsulates the over-designed and old-fashioned classes and methods into easy-to-use static modules and functions. It also brings modern C# syntax like LINQ and lambdas (functional programming) to AutoCAD development. With all the features it provides, you can save over half the lines of your code.
We temporarily provide sources and binaries for AutoCAD R18 (2010, 2011, 2012) and .NET 3.5. You can target R17 or R19 with the source files and build yourself, but there should be some problems due to API difference. We will officially publish ports for R19 soon.
View Test.cs for API usage examples.
The library consists of the following modules:
Drawto directly draw entities (with AutoCAD-command-like functions)NoDrawto create in-memory entitiesModifyto edit entities (with AutoCAD-command-like functions)Annotationto draw annotationsDbHelperto manipulate the DWG databaseQuickSelectionto simplify entity manipulation with LINQ style coding experience (like jQuery, if you know some Web)Interactionto handle user interactionsAlgorithmsto offer some mathematical helpersMultiDocto process cross-document scenariosCustomDictionaryto help you attach data to entitiesSymbolPackto help you draw symbols like arrows, etc.IronPythonto allow you use IronPython in AutoCAD
You may write this elegant code with the code pack:
/// <summary>
/// Eliminate zero-length polylines
/// </summary>
[CommandMethod("PolyClean0", CommandFlags.UsePickSet)]
public static void PolyClean0()
{
ObjectId[] ids = Interaction.GetSelection("\nSelect polyline", "LWPOLYLINE");
int n = 0;
ids.QForEach<Polyline>(poly =>
{
if (poly.Length == 0)
{
poly.Erase();
n++;
}
});
Interaction.WriteLine("{0} eliminated.", n);
}instead of the verbose version using original API:
[CommandMethod("PolyClean0_Old", CommandFlags.UsePickSet)]
public static void PolyClean0_Old()
{
string message = "\nSelect polyline";
string allowedType = "LWPOLYLINE";
Editor ed = Application.DocumentManager.MdiActiveDocument.Editor;
PromptSelectionOptions opt = new PromptSelectionOptions { MessageForAdding = message };
ed.WriteMessage(message);
SelectionFilter filter = new SelectionFilter(new TypedValue[] { new TypedValue(0, allowedType) });
PromptSelectionResult res = ed.GetSelection(opt, filter);
if (res.Status != PromptStatus.OK)
{
return;
}
ObjectId[] ids = res.Value.GetObjectIds();
int n = 0;
Database db = HostApplicationServices.WorkingDatabase;
using (Transaction trans = db.TransactionManager.StartTransaction())
{
foreach (ObjectId id in ids)
{
Polyline poly = trans.GetObject(id, OpenMode.ForWrite) as Polyline;
if (poly.Length == 0)
{
poly.Erase();
n++;
}
}
trans.Commit();
}
ed.WriteMessage("{0} eliminated.", n);
