How to extrude imported dxf along polyline?

[Anonymous]

I have region is in external dxf file,

how to extrude it along polyline?

I can't get region after using dxfin method

                    Database myDxfDb = new Database(false, true);
                    myDxfDb.DxfIn(filename, logFilename);
                    Matrix3d dxfTrf = Matrix3d.Identity;
                    _ThisDatabase.Insert(dxfTrf, myDxfDb, true);
                    _ThisDatabase.UpdateExt(true);
                    myDxfDb.Dispose();
                    acTrans.Commit();

                    ObjectId id = AcUtils.EntLast();
                    Entity _ent = (Entity)acTrans.GetObject(id, OpenMode.ForWrite);

Hi,

look to the objecttype that is the result of inserting the DXF ==> is it a region or is it a block(definition/-reference....) 😉

Hi alfred,

yes, I can that. dxf import as block reference.

well, how can I use this block reference 🙂

[Alfred.NESWADBA]

Hi,

either explode it or use the BlockTableRecord from this object to get the parts of this blockdefinition, there you also find then the region. You can then create an extrusion if this and add it to the database.

Good luck, -  alfred -

Hi,

and a sample for how to create 3D-solids from 2D-objects could be found >>>here<<< (and Kean Walmsley has a lot more interesting samples on his site)

I found the solution

        public Entity ImportDxfAsEntity(string FileName, Point3d InsertionPoint, double Rotation = 0)
        {
            ObjectId blkid = ObjectId.Null;
            Entity ent = null;
            using (Database bdb = new Database(false, true))
            {
                bdb.DxfIn(FileName, @"c:\log.txt");
                //blkid = _ThisDatabase.Insert(System.IO.Path.GetFileNameWithoutExtension(FileName), bdb, true);
                blkid = _ThisDatabase.Insert("blok", bdb, true);
                using (Transaction tr = _ThisDatabase.TransactionManager.StartTransaction())
                {
                    BlockReference bref = new BlockReference(InsertionPoint, blkid);
                    using (BlockTableRecord btAttRec = (BlockTableRecord)bref.BlockTableRecord.GetObject(OpenMode.ForWrite))
                    {
                        foreach (ObjectId subid in btAttRec)
                        {
                            ent = (Entity)subid.GetObject(OpenMode.ForRead);
                        }
                    }
                    tr.Commit();
                }
            }
            return ent;
        }
