Create Assembly with SubAssembly in C#

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!
