Recognition of dimension sets is a prerequisite for engineering drawings interpretation. A new heuristic algorithm for dimension sets recognition is presented. Following the recognized text strings, the algorithm recognizes the dimension lines and other components of the dimension set according to the dimension set syntaxes. The advantages of this algorithm to the architectural drawings are unm...

In this paper, a novel, adaptive noise reduction method for engineering drawings is proposed based on assessment of both primitives and noise. Unlike the current approaches, our method takes into account the special features of engineering drawings and assesses the characteristics of primitives and noise such that adaptive procedures and parameters are applied for noise reduction. For this purp...

An important role in software engineering is played by design notations. The Agent UML (AUML) notation for sequence diagrams has been widely used to capture the design of interactions between agents. However, AUML is not precisely defined, and there is very little in the way of tool support available. We argue that using a textual notation allows the notation to be precisely defined, and facili...

The theory of using Building Information Modelling “BIM” has been used in several Heritage places in the worldwide, in the case of conserving, documenting, managing, and creating full engineering drawings and information. However, one of the most serious issues that facing many experts in order to use the Historical Building Information Modelling “HBIM”, is creating the complicated architectura...

Technical drawing is very important for mechanical engineers. The ability to understand and work with technical drawings is a necessary skill for most of them. In general, first year students of mechanical engineering have difficulties in drawing orthographic views and perspectives, since they find it difficult to understand 3D shapes from 2D views. In this paper, we present several tools that ...

We describe a methodology and associated system for the interpretation of images of engineering drawings based on the exploitation of the Unix tool Yacc. The system is extensible and clearly relates a hypothesis/prediction/verification strategy to a hierarchical model description and the deployment of low level techniques. Examples are given of the interpretation of real mechanical engineering ...

This article presents a novel educational software package which develops an Interactive Didactic Application (IDA) created by the Polytechnic University of Catalonia (UPC), and which contains the essentials of textile design. It is an open application which uses a database in ASCII format. The principal elements of this database are lists of whole numbers structured according to indexed colors...

The recognition of symbols in graphic documents is an intensive research activity in the community of pattern recognition and document analysis. A key issue in the interpretation of maps, engineering drawings, diagrams, etc. is the recognition of domain dependent symbols according to a symbol database. In this work we first review the most outstanding symbol recognition methods from two differe...
