I want to develop a plugin to select a layer and create a table with the objects data, for example, the size of all circles that are in certain selected layer.

I'm new to Autocad API.NET, I'll be grateful for the help.

I'm using Autocad Civil 3D.

Here is a example for CIRCLES

In Autocad, you can use the command MYTABLE and select a object and get all circles on this layer in a table.

In your main file do something like this:

Tools.LayerToTable layerToTable = null; [CommandMethod("MYTABLE")] public void MyTable() { if (layerToTable == null) { layerToTable = new Tools.LayerToTable(); } try { layerToTable.GetObjectsOnLayer(); } catch (System.Exception e) { MessageBox.Show("Original error: " + e.Message); } }

Then make a new file (LayerToTable.cs) and paste this code:

using Autodesk.AutoCAD.ApplicationServices; using Autodesk.AutoCAD.DatabaseServices; using Autodesk.AutoCAD.EditorInput; using acApp = Autodesk.AutoCAD.ApplicationServices.Application; using System.Linq; using System.Collections.Generic; using Autodesk.AutoCAD.Interop.Common; using Autodesk.AutoCAD.Interop; using Autodesk.AutoCAD.Geometry; using Autodesk.AutoCAD.Colors; using System; namespace Tools { public partial class LayerToTable { public void GetObjectsOnLayer() { // Use the active document Document doc = acApp.DocumentManager.MdiActiveDocument; Database db = doc.Database; Editor ed = doc.Editor; // Select a object PromptSelectionOptions pso = new PromptSelectionOptions(); pso.SingleOnly = true; pso.SinglePickInSpace = true; PromptSelectionResult Selection = ed.GetSelection(pso); if (Selection.Status == PromptStatus.OK) { using (Transaction tr = db.TransactionManager.StartTransaction()) { try { // Get the selected entity Entity SelectedEntity = (Entity)(tr.GetObject(Selection.Value.OfType<SelectedObject>().First().ObjectId, OpenMode.ForRead)); try { // Create the selection set PromptSelectionResult acSSPrompt = null; try { try { TypedValue[] acTypValAr = new TypedValue[4]; acTypValAr.SetValue(new TypedValue(67, 0), 0); // Model space = 0, paper space = 1 acTypValAr.SetValue(new TypedValue((int)DxfCode.Visibility, 0), 1); // Visible = 0, invisible = 1 acTypValAr.SetValue(new TypedValue((int)DxfCode.LayerName, SelectedEntity.Layer), 2); // Layer name acTypValAr.SetValue(new TypedValue((int)DxfCode.Start, "CIRCLE"), 3); // Circle SelectionFilter acSelFtr = new SelectionFilter(acTypValAr); // Select all entities on the selected object layer acSSPrompt = ed.SelectAll(acSelFtr); } catch (System.Exception ex) { acApp.ShowAlertDialog("Filter error. Original error: " + ex.Message); } if (acSSPrompt.Value.Count <= 0) { acApp.ShowAlertDialog("no objects selected."); return; } // Create a list with all circles in the selection List<Tuple<Circle, Point3d, double>> circles = new List<Tuple<Circle, Point3d, double>>(); try { foreach (SelectedObject obj in acSSPrompt.Value) { try { using (Circle circle = (Circle)obj.ObjectId.GetObject(OpenMode.ForRead)) { circles.Add(new Tuple<Circle, Point3d, double>(circle, circle.Center, circle.Radius)); } } catch { // All objects except circles... //acApp.ShowAlertDialog("Using circle error (not a circle?)"); } } } catch { acApp.ShowAlertDialog("ObjectId error"); } // Start creating the table if (circles.Count > 0) { try { bool result = CrateTable(circles); if (!result) acApp.ShowAlertDialog("Table not created."); } catch (System.Exception ex) { acApp.ShowAlertDialog("CreateTable() error.

I did everything as per your instructions, however, I can't find it by running the "MYTABLE" command in Civil3D.Main fileLayerToTable

Your main file should look something like this one:

using System; using System.Windows.Forms; using Autodesk.AutoCAD.Runtime; [assembly: CommandClass(typeof(Tools.index))] namespace Tools { public class index : IExtensionApplication { public void Initialize() { } public void Terminate() { throw new NotImplementedException(); } Tools.LayerToTable layerToTable = null; [CommandMethod("MYTABLE")] public void MyTable() { if (layerToTable == null) { layerToTable = new Tools.LayerToTable(); } try { layerToTable.GetObjectsOnLayer(); } catch (System.Exception e) { MessageBox.Show("Original error: " + e.Message); } } } }

And you have to load this dll in autocad with the NETLOAD command. (or load it with a lisp file on startup)

I managed to execute, however, when inserting the points of the table I could not understand the code execution.select layersinsert table pointserror defining table

key not found?

i don't use civil. pearhaps in civil some table keys don't exist.

try { acTable.SetTextHeight((int)AcRowType.acTitleRow, 3); acTable.SetTextHeight((int)AcRowType.acHeaderRow, 2); acTable.SetTextHeight((int)AcRowType.acDataRow, 2); acTable.SetTextStyle((int)AcRowType.acTitleRow, "Arial"); acTable.SetTextStyle((int)AcRowType.acHeaderRow, "Arial"); acTable.SetTextStyle((int)AcRowType.acDataRow, "Arial"); acTable.RowHeight = defaultRowHeight; acTable.Layer = tableLayer; } catch (System.Exception ex) { acApp.ShowAlertDialog("Error define table. Original error: " + ex.Message); return false; }

I think (int)acRowType is the key.

you can try to comment out those lines. but i can't say exactly what the problem is.
