get constraint Type

joantopo — Mon, 02 Dec 2013 17:44:03 GMT

Hi.

I have a profile with entities.

   using (Transaction trans = HostApplicationServices.WorkingDatabase.TransactionManager.StartTransaction())
           {

               Autodesk.Civil.DatabaseServices.Profile perfil = default(Autodesk.Civil.DatabaseServices.Profile);
               perfil = trans.GetObject(entRes.ObjectId, OpenMode.ForWrite) as Profile; 

   foreach(ProfileEntity entity in perfil.Entities)
               {
                   ProfileEntityType tipo = entity.EntityType;
                   if (tipo == ProfileEntityType.ParabolaSymmetric || tipo == ProfileEntityType.ParabolaAsymmetric || tipo == ProfileEntityType.Circular)
                   {
                       aB = new EntitiesProfile();
                       aB.EndStation = Pkinicial + Math.Abs(PKfinal - entity.StartStation);   //lo ponemos al revés porque al invertir el perfil ya lo tendré con los datos correctos.
                       aB.EndElevation = entity.StartElevation;
                       aB.StartStation = Pkinicial + Math.Abs(PKfinal - entity.EndStation);
                       aB.StartElevation = entity.EndElevation;

                    

                       aB.entityType = entity.EntityType;

                       aB.Length = entity.Length;
                       aB.Constraint1 = entity.Constraint1;
                       aB.Constraint2 = entity.Constraint2;


                       switch (entity.EntityType)
                       {
                           case ProfileEntityType.ParabolaSymmetric:
                               ProfileParabolaSymmetric parábolaSym = (ProfileParabolaSymmetric)entity;


                               aB.kv = parábolaSym.K;
                               aB.VerticalCurveType = parábolaSym.CurveType;



                               if (entity.Constraint1 == ProfileEntityConstraintType.Fixed)
                               {
                                   if (entity.Constraint2.GetType() == typeof(Autodesk.Civil.DatabaseServices.ProfileEntityConstraintType.................))
                                   {
                                   }

I could do this:

if(entityConstraint2.GetType.ToString() == ".........................."  ;

or I could save TypeCode in my List.

aB.TypeCode= entity.Constraint2.GetTypeCode, but I don´t have the table of those codes. ¿?

I would like write with "typeof(.....)" and put my own code in my List.

Thank you.

Sorry.

I have already solution:

 if (entity.Constraint2 == EntityVerticalConstraintType.PassThroughPt)
                                   {
                                   }

Hi,

Sorry for replying your old post, but I got stuck on clone entities(Circular, ParabolaSymmetric,ParabolaAsymmetric, etc) from a Profile.

Were you trying to copy entities of a Profile?

Thanks

I did a rutine to get a reverse layout profile.

So my command did a new layout profile and create new elements in the profile.

I had to "read" the parameters of the elements and then change the order start station to end station and so on.

Thank you for your quick reply!

Your command did more complicated than I thought.

Actually, I am going to clone a Profile and I am totally lost on understanding Vertical Curve of Profile. Could you please correct me of concepts about it below?

-Profile Entities

---- Tangents(ProfileEntityType.Tangent)

---- Vertical Curves

---- circulars(ProfileEntityType.Circular)

---- Parabolas

---- Symmetric(ProfileEntityType.ParabolaSymmetric)

---- Asymmetric(ProfileEntityType.ParabolaAsymmetric)

I can get EntityId of a Vertical Curve by ProfilePVI.VerticalCurve.EntityId , no matter what kind curve(circular/Symmetic parobola/ Asymmetric parobola) it is
some properties are applicable/common within all 3 kinds of vrtical curve, for example, StartStation/EndStation/Length/Constraint1/Constraint2
other properties are different with each other, so have to be set separately , divide by "switch case"

Question:

1. Is it a good idea to loop Profile.PVIs to get all entities on a Profile, I can only get EntityId by ProfilePVI.VerticalCurve.EntityId?

2. Or will you prefer loop PrifileEntities to get all entites? but I don't know how to get its PVI by a ProfileEntity.

3. For Sysmmetic Parobola, there are "fixed Symmetric Parabola " and " a floating Symmetric Parabola " , what is the difference when I create/add it to a Profile?

Sorry for long questions.
