• 读取DWG文件

   using CADImport; using CADImport.DWG; using CADImport.DXF; using CADImport.RasterImage;           

   private void Read_DWG_Click(object sender, EventArgs e)        {            //DWGImage class is used only for reading DWG. To read otherformatsuse the corresponding classes.            //E.g. for DXF: CADImage class, for PLT/HPGL: HPGLImage class.            DWGImage vDrawing = new DWGImage();            vDrawing.LoadFromFile(@"......FilesGasket.dwg");            vDrawing.Draw(Image1.CreateGraphics(), new RectangleF(0, 0,(float)vDrawing.AbsWidth, (float)vDrawing.AbsHeight));            // zooming and panning of the drawing are implemented in the demoViewer            // via a special viewing control class CADPictureBox        }
