Functionality: Weighted Links Theoretical Background: Simulation-News in Creo 1.0 & 2.0 & 3.0  /  Weighted Links: "Tips & Tricks" 21 • It is not easy to understand how weighted links work; in case of doubts try it out on a simple model.  • Real structures, who are idealized with help of rigid or weighted links, often behave somehow in between: They are neither infinite stiff nor do not add any stiffness.  • A big advantage of weighted links compared to rigid links is that there are no stiffness jumps at the edges of their referenced surfaces, the surfaces can still deform.  • So, a weighted link is a good idealization e.g. to built cylindrical joints: Connect a beam end point (the beam represents the axis) as dependent point to the bearing hole surface (=independent surface).
