Create an orthographic view via the C# API

Dear All!
How can I create an orthographic view via the C# API? I'm trying to use the PnP3dOrthoDrawingsUI.dll, which has a CreateOrthos() function. However, I'm having some problems: I cannot programmatically select the viewport placement points on the drawing using the C# API. Currently, I have to use the mouse to pick the points manually.

public static void CreateOrthoView()
{
var doc = Application.DocumentManager.MdiActiveDocument;
var db = doc.Database;
var ed = doc.Editor;

try
{
var selectedModels = new StringCollection();

selectedModels.Add(@"D:\Annh\Plant3D Tool\Plant 3D Project\Test_Project_001\Plant 3D Models\001.dwg");
string viewName = "FrontView";

double scale = 0.5;

double viewportWidth = 250;
double viewportHeight = 250;
double viewportDepth = 500.0;

Commands.ViewType viewType = Commands.ViewType.Front;
string strViewType = "FrontView";

Vector3d viewDir = new Vector3d(1, 0, 0);

Vector3d upVector = new Vector3d(0, 0, 1);

Point3d lowerLeftPt = new Point3d(0, 0, -250);

Point3d upperRightPt = new Point3d(500, 500, 250);

var cubeSolid = new Solid3d();

cubeSolid.CreateBox(500, 500, 500);

var orthoView = new PlantOrthoView();

orthoView.CreateOrthos(
selectedModels, viewName, scale, viewportWidth, viewportHeight, viewportDepth, viewType,
strViewType, viewDir, upVector, lowerLeftPt, upperRightPt, cubeSolid);

}
catch (Exception ex)
{
ed.WriteMessage("\n❌ Error: " + ex.Message);
}
}

Thank you very much for your support!
