Create Assembly with SubAssembly in C#

[alexis.nunez98YHM]

Hi,

I'm trying to create Civil3d assembly with connected subassembly. I'm trying to access the Assembly group but no avail. Im using 2023 version of Civil3d. 

Please check the below code that I created:

void _CreateAssembly_1()
        {
            var doc = Application.DocumentManager.MdiActiveDocument;
            var db = doc.Database;
            var ed = doc.Editor;
            CivilDocument civilDoc = CivilDocument.GetCivilDocument(doc.Database);
            Point3d pntLoc = cSelection.Select_Point3d("Select Target Location");
 
            if (pntLoc == new Point3d(0, 0, 0)) return;
            using (doc.LockDocument())
            {
                using (Transaction tr = doc.TransactionManager.StartTransaction())
                {
                    BlockTable bt = (BlockTable)tr.GetObject(db.BlockTableId, OpenMode.ForRead);
                    BlockTableRecord ms = (BlockTableRecord)tr.GetObject(bt[BlockTableRecord.ModelSpace], OpenMode.ForWrite);
                    //acc3db.Assembly oAsm = new acc3db.Assembly();
 
                    ObjectId AssemblyId = civilDoc.AssemblyCollection.Add("test2", acc3db.AssemblyType.Other, pntLoc);
 
                    acc3db.Subassembly asm = AssemblyId.GetObject(OpenMode.ForWrite) as acc3db.Subassembly;
 
                    //civilDoc.SubassemblyCollection.Add("GEC_Carriageway_5layer",)
 
                    listBox1.Items.Clear();
                    // List Sub Assembly
                    foreach (var o in civilDoc.SubassemblyCollection)
                    {
                        acc3db.Subassembly subasm = o.GetObject(OpenMode.ForRead) as acc3db.Subassembly;
                        listBox1.Items.Add("  " + subasm.Name + " - " + subasm.Name);
                    }
                     
                    // Create the CW subassembly                    
                    ObjectId subAsmId_R = civilDoc.SubassemblyCollection.ImportSubassembly("GEC_Carriageway_5layer_R_2", @"C:\ProgramData\Autodesk\C3D 2023\enu\Imported Tools\GEC_Carriageway_5_layer\af8a6c22d9e746f895aad89dcfcc3f42.atc", "43365f65-e04b-4df4-98ba-c308d3e806b4", pntLoc.Add(new Vector3d(0, 0, 0)));
                    ObjectId subAsmId_L = civilDoc.SubassemblyCollection.ImportSubassembly("GEC_Carriageway_5layer_L_2", @"C:\ProgramData\Autodesk\C3D 2023\enu\Imported Tools\GEC_Carriageway_5_layer\af8a6c22d9e746f895aad89dcfcc3f42.atc", "43365f65-e04b-4df4-98ba-c308d3e806b4", pntLoc.Add(new Vector3d(0, 0, 0)));
 
                    acc3db.Subassembly sub = (acc3db.Subassembly)subAsmId_R.GetObject(OpenMode.ForWrite);
                    acc3db.Subassembly sub_L = (acc3db.Subassembly)subAsmId_L.GetObject(OpenMode.ForWrite);
 
                    foreach (var o in sub_L.ParamsLong)
                    {
                        if (o.DisplayName.ToUpper() == "SIDE") o.Value = 1;
                    }
                    tr.Commit();
                }
            }
        }

Thank I was able to correct the code. Now my problem is to add another subassembly which is connected to subassembly. 

                    BlockTable bt = (BlockTable)tr.GetObject(db.BlockTableId, OpenMode.ForRead);
                    BlockTableRecord ms = (BlockTableRecord)tr.GetObject(bt[BlockTableRecord.ModelSpace], OpenMode.ForWrite);
                    //acc3db.Assembly oAsm = new acc3db.Assembly();

                    ObjectId AssemblyId = civilDoc.AssemblyCollection.Add("test2", acc3db.AssemblyType.Other, pntLoc);

                    acc3db.Assembly asm = AssemblyId.GetObject(OpenMode.ForWrite) as acc3db.Assembly;

                    

                    //civilDoc.SubassemblyCollection.Add("GEC_Carriageway_5layer",)

                    listBox1.Items.Clear();
                    // List Sub Assembly
                    listBox1.Items.Add("------------ SubAssembly Collection START - " + civilDoc.SubassemblyCollection.Count);
                    foreach (var o in civilDoc.SubassemblyCollection)
                    {
                        acc3db.Subassembly subasm = o.GetObject(OpenMode.ForRead) as acc3db.Subassembly;
                        listBox1.Items.Add("  " + subasm.Name + " - " + subasm.Name);
                    }
                    listBox1.Items.Add("------------ END - " + civilDoc.SubassemblyCollection.Count);

                    // Create the CW subassembly
                    //ObjectId subAsmId = civilDoc.SubassemblyCollection.ImportSubassembly("GEC_Carriageway_5layer", @"C:\ProgramData\Autodesk\C3D 2023\enu\Imported Tools\GEC_Carriageway_5_layer\af8a6c22d9e746f895aad89dcfcc3f42.atc", "{2fb63dad-6d59-4bed-9de7-d90f091e4a29}", pntLoc.Add(new Vector3d(0,2,0)));
                    ObjectId subAsmId_R = civilDoc.SubassemblyCollection.ImportSubassembly("GEC_Carriageway_5layer_R_2", @"C:\ProgramData\Autodesk\C3D 2023\enu\Imported Tools\GEC_Carriageway_5_layer\af8a6c22d9e746f895aad89dcfcc3f42.atc", "43365f65-e04b-4df4-98ba-c308d3e806b4", pntLoc.Add(new Vector3d(0, 0, 0)));
                    ObjectId subAsmId_L = civilDoc.SubassemblyCollection.ImportSubassembly("GEC_Carriageway_5layer_L_2", @"C:\ProgramData\Autodesk\C3D 2023\enu\Imported Tools\GEC_Carriageway_5_layer\af8a6c22d9e746f895aad89dcfcc3f42.atc", "43365f65-e04b-4df4-98ba-c308d3e806b4", pntLoc.Add(new Vector3d(0, 0, 0)));

                    acc3db.Subassembly sub = (acc3db.Subassembly)subAsmId_R.GetObject(OpenMode.ForWrite);
                    acc3db.Subassembly sub_L = (acc3db.Subassembly)subAsmId_L.GetObject(OpenMode.ForWrite);


                     
                    acc3db.AssemblyGroup AsmGrp_R = asm.AddSubassembly(subAsmId_R);
                    AsmGrp_R.Name = "Right";
                    acc3db.AssemblyGroup AsmGrp_L = asm.AddSubassembly(subAsmId_L);
                    AsmGrp_L.Name = "Left";

                    UpdateSubAssemblyParameters(sub_L, "Side", "1");

The output of the above code is this:

I want to add another subassembly like the one below:

Can you provide a sample pls.

 I'm also creating assembly with code for the first time.

Civil 3d 2018

public void C_AssTest()
{

    Document doc = Application.DocumentManager.MdiActiveDocument;

    var assId = CivilApplication.ActiveDocument.AssemblyCollection.Add("Test", AssemblyType.UndividedCrownedRoad, Point3d.Origin);
    var subAssId1 = CivilApplication.ActiveDocument.SubassemblyCollection.ImportStockSubassembly("BaseLane", "Subassembly.BasicLane", Point3d.Origin);
    var subAssId2 = CivilApplication.ActiveDocument.SubassemblyCollection.ImportStockSubassembly("ShapeTrapezoidal", "Subassembly.ShapeTrapezoidal", Point3d.Origin);

    using (Transaction tr = doc.TransactionManager.StartTransaction())
    {
        var ass = assId.GetObject(OpenMode.ForWrite) as Assembly;
        var assGroup1 = ass.AddSubassembly(subAssId1);
        assGroup1.Name = "Right";

        var assgroup2 = ass.MirrorSubassembly(subAssId1);
        assgroup2.Name = "Left";

        var subAss1 = subAssId1.GetObject(OpenMode.ForRead) as Subassembly;
        var subAss2 = assgroup2.GetSubassemblyIds()[0].GetObject(OpenMode.ForRead) as Subassembly;

        // Find Right Top Point
        var pt1 = (from x in subAss1.Points
                   orderby x.Offset descending, x.Elevation descending
                   select x).First();
        // add Second Subassembly to Right Group
        if (pt1 != null)
        {
            ass.AddSubassembly(subAssId2, pt1);
        }
        var pt2 = (from x in subAss2.Points
                   orderby x.Offset descending, x.Elevation descending
                   select x).First();
        if (pt2 != null)
        {
            ass.MirrorSubassembly(subAssId2, pt2);
        }
        tr.Commit();
    }
}

I managed to find a solution but your sample here is better. I think I will use this kind of approach.
Thank you very much!
