Abstract
Engineering drawing has become essentials to most organization be it consultants, contractors or even government sectors. To get the information from an engineering drawing, entities must be filtered in order to extract the accurate information. This research presents the entities filtering technique for information extraction in engineering drawing files. The technique filtered the entities based on four attributes which are layer, color, entity type and line type. Ten engineering drawings files was used for testing, showing that the entities filtering technique is able to extract all the entities.
