• 讀取DWG文件

<code> using CADImport;
 using CADImport.DWG;
 using CADImport.DXF;
 using CADImport.RasterImage;                   /<code>

<code> private void Read_DWG_Click(object sender, EventArgs e)
        {
            //DWGImage class is used only for reading DWG. To read other
formatsuse the corresponding classes. 
            //E.g. for DXF: CADImage class, for PLT/HPGL: HPGLImage class.
            DWGImage vDrawing = new DWGImage();
            vDrawing.LoadFromFile(@"..\\..\\..\\Files\\Gasket.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 demo
Viewer
            // via a special viewing control class CADPictureBox
        }  /<code>
