a r t i c l e i n f o Construction planning is a fundamental and challenging process in the management and execution of construction projects. The task of developing technical plans is critical to ensuring the success of a construction project. This task of preparing a technical plan is usually undertaken manually using two separate processes: (1) plan definition and (2) verification/checking. ...

This paper presents a new approach to classify, index and retrieve technical drawings by content. Our work uses spatial relationships, shape geometry and highdimensional indexing mechanisms to retrieve complex drawings from CAD databases. This contrasts with conventional approaches which use mostly textual metadata for the same purpose. Creative designers and draftspeople often re-use data from...

quality of products and services is considered as a key factor for customer satisfaction. quality function deployment (qfd) is known as a critical tool for translating voice of customers to prioritize technical requirements of a production. the level of this satisfaction depends on the number of fulfilled requirements. it should be noted that this level varies according to the possible constrai...

Playing with physical construction kits (Legos, Erector sets, Fischer-Technik, etc.) is a good way to build physical intuitions and spark interest in technical fields. Construction kits for virtual artifacts could have similar benefits, with complementary advantages and disadvantages. Yet we currently do not have construction kits for virtual analogs of physical artifacts that provide the same ...
