  1. Óbuda University John von Neumann Faculty of Informatics Institute of Applied Mathematics CourseIntroduction to virtual engineering Lecture and laboratory 5. Positioning and moving related shapes László Horváth university professor http://users.nik.uni-obuda.hu/lhorvath/

  2. Contents Lecture Positional relationships of solid shapes in model space Keeping constraints at modification of related solid shapes Creating mechanisms by adding relative movements to solid shapes Laboratory Placing and modification of relationships at connection of components (VE5.1) Definition of mechanism and simulation of kinematics (VE5.2) LászlóHorváth ÓU-IAM http://users.nik.uni-obuda.hu/lhorvath/
