Autocad ortamında oluşturulan 2B'lu çizimlerden 3B'lu katı modellerin elde edilmesi

AutoCAD ortamında oluşturulan 2B'lu çizimlerden 3B'lu katı modellerin elde edilmesi konusunda bir çalışma yapılmıştır. Bu çalışma ile bir bilgisayar programı geliştirilerek kullanıcı tarafindan AutoCAD ortamında oluşturulan 2B'lu silindirik ve prizmatik parçaların görünüşleri bilgisayar programı yardımıyla DXF formatında kaydedilmektedir. Çizime ait geometrik bilgiler program tarafından yorumlanarak silindirik ve prizmatik katının birincil ve ikincil ilkelleri dönel ve lineer süpürme operasyonları ile elde edilmektedir. Daha sonra ikincil ilkeller birincil ilkellerden Boolean operasyonları yardımıyla çıkarılmakta ve silindirik son katı modeller tamamlanmaktadır. Prizmatik son katı modeller ise, birincil ilkeller bir araya getirilerek elde edilmektedir. Programlama dili olarak VisualLISP programlama dili kullanılmıştır.

Reconstruction of 3Dsolid models from 2D drawings generated in autocad

A research work regarding reconstruction of 3D solid models from 2D drawings generated in AutoCAD has been performed. With this work, a computer program has been developed. The orthographic views of 2D cylindrical and prismatic parts drawn by the user in AutoCAD are saved in DXF format through the use of the program developed. Having been evaluated the geometric information by the program, primary and secondary primitives of cylindirical and prismatic solids are obtained by rotational and linear sweeping operations. Then, secondary primitives are subtracted from primary primitives by Boolean operations and cylindirical final solid models are completed. Prismatic final solid models are obtained by combining of primary primitives. VisualLISP was used as a programming langauage.
