Extrude in vertical direction using C#

Jiri Mares

Hello everybody,

just a quick question regarding using Extrude command from .NET environment. I would like to extrude a region in vertical direction similar to Bricscad command Extrude/Direction.
I did:

                            Region regi = (Region)acTrans.GetObject(ids[i], OpenMode.ForRead);                            Solid3d pSolid = new Solid3d();                            pSolid.RecordHistory = true;                            pSolid.Extrude(regi, 1000, 0);
This extrudes my region perpendicular to the plane of region. I would like this to be in vertical z axis. 
Not sure what the most efficient way is.

Please advise

many thanks

Jiri

try defining the extrusion direction you wish by picking 2 points....
         Vector3d  dVector = new Vector3d();
         Double  eXheight = 0.0;

// Select the wished extrusion direction
         Point3d p1 = ed.GetPoint("Start point of extrusion direction :").Value;
         Point3d p2 = ed.GetPoint("End point of extrusion direction :").Value;

// the direction vector
         dVector = new Vector3d(p2.X - p1.X, p2.Y - p1.Y, p2.Z - p1.Z);

//   ......selection set in editor

         SelectionSet ss = pSelres.Value;
         ObjectId[] idarray = ss.GetObjectIds();
         Entity[] lps = new Entity[ss.Count];
         Entity regEnt = trans.GetObject(idarray[0], OpenMode.ForRead) as Entity;

//// create the extruded solid using your selected region ...

         Solid3d sol = new Solid3d();
         sol.CreateExtrudedSolid(regEnt, dVector, new SweepOptionsBuilder());
                           
 // ... and add it to the modelspace
         ms.AppendEntity(sol);
         trans.AddNewlyCreatedDBObject(sol, true);

hope this helps !
