PortType 的理解

image.png image.png

static 为数据库定义的点
dynamic 为比如在pipe上创建支架后动态生成的2个port
symbolic 暂时还未碰到

public enum PortType
{
    Static = 1,
    Dynamic = 2,
    Both = 3,
    Symbolic = 4,
    All = 7
}

var doc = Application.DocumentManager.MdiActiveDocument;
var ed = doc.Editor;
var db = doc.Database;
using (var tr = db.TransactionManager.StartOpenCloseTransaction())
{
    var select = ed.GetSelection();
    if (select.Status != PromptStatus.OK) return;
    foreach (SelectedObject sel in select.Value)
    {
        var ent = tr.GetObject(sel.ObjectId, OpenMode.ForRead);
        Console.WriteLine($"{ent}");

        if (ent is Autodesk.ProcessPower.PnP3dObjects.Part part)
        {
            foreach (Autodesk.ProcessPower.PnP3dObjects.Port p in part.GetPorts(PortType.All))
            {
                Console.WriteLine($"\t{p.Name} {p.Position} {p.Direction} {p.NominalDiameter}");
            }
        } 
    }

}
