A library of helpful dialogs and helper methods to use with your Autodesk Civil 3D .NET projects.
I created this library to be used with multiple of my Civil 3D projects. It contains common dialogs that I have used and created.
- SelectAlignmentDialog
- SelectSurfaceDialog
- SelectPointGroupDialog
- LayerSelectDialog
- LayerCreateDialog
var dialog = new SelectAlignmentDialog();
if (dialog.ShowModal() == true)
var alignment = dialog.SelectedAlignment;
var surfaces = CivilApplication.ActiveDocument.GetSurfaceIds();
Surface selectedSurface;
if (surfaces.Count > 1)
var dialog = new SelectSurfaceDialog();
if (dialog.ShowModal == true)
selectedSurface = dialog.SelectedSurface;
else
selectedSurface = //Get first surface
var dialog = new SelectPointGroupDialog();
if (dialog.ShowModal() == true)
var pointGroup = dialog.SelectedPointGroup;
var dialog = new LayerCreateDialog();
dialog.ShowModal();
if (dialog.Layer == null)
return;
using var tr = Application.DocumentManager.MdiActiveDocument.TransactionManager.StartTransaction();
var layerTable = (LayerTable)tr.GetObject(Application.DocumentManager.MdiActiveDocument.Database.LayerTableId, OpenMode.ForRead);
if (layerTable.Has(dialog.Layer.Name))
return;
layerTable.UpgradeOpen();
layerTable.Add(dialog.Layer);
tr.AddNewlyCreatedDBObject(dialog.Layer, true);
tr.Commit();
