It is a time consuming process to redraw technical drawings which have been drawn earlier using a CAD program. In this study, a computer program software has been developed for converting two dimensional pictures, which were scanned or photos taken and saved in bitmap (*.BMP) format, into vector graphics data format (*.DWG) which can be used in AutoCAD environment using VB (Visual Basic) and VBA (Visual Basic Application) programming language. First of all the pictures to be converted into CAD data format which have been saved as 24 bit and 800x600 pixels in black and white and have bitmap file extension are scanned and processed pixel by pixel horizontally and vertically. The (X, Y) coordinates of the objects in the picture are determined and coordinate points are saved in text (*.TXT) format. Then the coordinate values in the text file are converted into DWG format using ActiveX commands and saved in a file
