Course Introduction to virtual engineering Óbuda University John von Neumann Faculty of Informatics Institute of Applied Mathematics Lecture and laboratory 12. Development of Contextual Chains László Horváth university professor http://users.nik.uni-obuda.hu/lhorvath/

Contents Lecture Laboratory Contextual curves and surfaces Solid in the context of surface László Horváth ÓU-IAM http://users.nik.uni-obuda.hu/lhorvath/ Definition and connection in contextual chains during engineering work Analyses of curves and surfaces in order to the demanded geometry Laboratory task VE12: Definition of complex solid through chains of contextual connections.

Multi-sections surface László Horváth ÓU-IAM http://users.nik.uni-obuda.hu/lhorvath/ Sweeping section curves along computed or defined spine Contextual connection of the feature are highlighted

Isoparameter curve and its scaled curve László Horváth ÓU-IAM http://users.nik.uni-obuda.hu/lhorvath/ YZ plane is used as reference element at the scaling of isoparametric curve.1 Isoparametric curves on multi- section surface

Sweep in the context of isoparametric and scaled curves László Horváth ÓU-IAM http://users.nik.uni-obuda.hu/lhorvath/

Kontextus definiálása transzformációval László Horváth ÓU-IAM http://users.nik.uni-obuda.hu/lhorvath/

Blended surface László Horváth ÓU-IAM http://users.nik.uni-obuda.hu/lhorvath/ Blended surface between two edges, taking tangency continuity contexts as constraints into account.

Joining three surfaces for definition of their common context László Horváth ÓU-IAM http://users.nik.uni-obuda.hu/lhorvath/

Solid shape in the context of join surface László Horváth ÓU-IAM http://users.nik.uni-obuda.hu/lhorvath/ Solid form feature between the join surface and its offset.

Surface – curve – surface contextual chain László Horváth ÓU-IAM http://users.nik.uni-obuda.hu/lhorvath/ Curves 3-4 are defined on solid boundary as curves on surface. Multi-sections surface is defined in their context.

Extrapolating surface in two directions László Horváth ÓU-IAM http://users.nik.uni-obuda.hu/lhorvath/ Extrapolated surfaces are defined in the context of the multi*sections surface

Solid shape in the context of extrapolated surface László Horváth ÓU-IAM http://users.nik.uni-obuda.hu/lhorvath/

Fillet in complex context László Horváth ÓU-IAM http://users.nik.uni-obuda.hu/lhorvath/

Sphere surfaces and solid features in their context László Horváth ÓU-IAM http://users.nik.uni-obuda.hu/lhorvath/

Tabulated solid in context László Horváth ÓU-IAM http://users.nik.uni-obuda.hu/lhorvath/ Contextual connection with solid boundary of a solid feature.

Surface in the context of surface in the boundary László Horváth ÓU-IAM http://users.nik.uni-obuda.hu/lhorvath/

Solid feature between the new and the boundary surfaces László Horváth ÓU-IAM http://users.nik.uni-obuda.hu/lhorvath/

Distance analysis László Horváth ÓU-IAM http://users.nik.uni-obuda.hu/lhorvath/

Draft analysis László Horváth ÓU-IAM http://users.nik.uni-obuda.hu/lhorvath/

Curvature analysis on curve László Horváth ÓU-IAM http://users.nik.uni-obuda.hu/lhorvath/

Curvature analysis on surface László Horváth ÓU-IAM http://users.nik.uni-obuda.hu/lhorvath/

Solid body as result of definition along contextual chains László Horváth ÓU-IAM http://users.nik.uni-obuda.hu/lhorvath/ Additional active formula, rule and other feature definitions can give self-adaptive control for the shape. Modified geometry must be feasible.
