Deep learning for digitising complex engineering drawings.
… required to analyse it. Amongst these documents, engineering drawings are considered one of the most challenging to digitise. The task involves automatically recognising all drawing components which are the symbols, text and connections. Although there has been significant improvement in computer …

Engineering Drawing Segmentation and Understanding For Building Construction Digital Twins
… Models (BIMs), even though they have detailed engineering drawings that contain essential mechanical, electrical, plumbing (MEP) components and structural components. Converting these drawings into BIM models remains a largely manual process, which is time-consuming, difficult to scale, and …

Modeling and fabrication of an Atlantic marine engine
… and manifold were developed from original engineering drawings, and the corresponding patterns and core molds for casting designed. The viability of CNC milled high-density foam for fabricating complex casting patterns and molds was demonstrated with the Atlantic engine cylinder and …

Design of an unloader for rotary compressors
… the design are worked out, and a complete set of engineering drawings is fully developed. A prototype of the mechanism was constructed; a brief description of the process is given. The last part of the thesis presents the experimental work done to prove the success of the concept, to assess the …

Automatic refinement of constructive solid geometry models
Geometric information relating to most engineering products is available in the form of orthographic drawings or 2D data files. For many recent computer based applications, such as Computer Integrated Manufacturing (CIM), these data are required in the form of a sophisticated model based on …

Design and development of a wind tunnel for the investigation of turbulent compressible mixing layers
… via an online catalog of fully-dimensioned engineering drawings for the as-built design. Experimental qualification of the newly-built wind tunnel was conducted in order to assess the suitability of the wind tunnel as a testbed for the compressible shear layer flowfield, and to produce …

Linking CAD and Metrology to Explain, Demonstrate, and Teach Geometric Dimensioning and Tolerancing
… surface table to accomplish this. A set of engineering drawings is created, and a 3D printer is used to produce imperfect parts. These imperfections are intended to represent signi cant manufacturing variation. Then using a portable CMM and the surface table, data points are taken to …

Assessing Impacts of Digital Sketching on Concept Generation in Early Stage Design
… products prior to production and easily creating engineering drawings for manufacturing. Artificial Intelligence (AI) tools are being explored as collaborators who assist designers with interpreting sketches, assessing user needs, and generating ideas. Digital sketching tools such as tablets are a …
