Good afternoon dear experts. Could someone of you explain the conceled hinge kinematics and how to build an interconnected algorithm in Grasshopper? Kinematics of Invisible Hinge (Trigonometric Analysis of the Motion of the Invisible Hinge with 7 Axes) CONCEALED HINGE - 7 AXIS - STEEL PLATES - 18…

After opening the Grasshopper file I posted above, all you need to do is switch on the Kangaroo solver and then drag the part in the front view. You need to drag somewhere close to the hinge points on the part and if the range needs to be bigger, you can increase it in the Grab component.

Daniel, To achieve this result (picture in app.), do I need 7 axes or can I use fewer axes? Could you please edit your Grasshopper file/script. I am unable to achieve the desired result (I am not very strong in kinematics). [image] [image] Thank you in advance for your help. Harald

Daniel, That is this the maximum degree that I could open. [image] Harald

Could someone suggest a platform where I can intuitively calculate dependencies (kinematics) for similar tasks? Harald

If you look at the Soss hinge pictured above, you can see that one of the hinges is actually sliding back and forth. I attached a Rhino model of a Soss hinge, maybe you have this already? Not sure how correct this model is but I think you should be able to retrieve the dimensions and hinge axis. so…

Thanks Martin, Yes, I have a similar model, but I can’t establish a link between the axes. Harald

Thanks Martin, But I need that when the panels turn 180 degrees (there was no gap between them). [image] Harald

Martin, Could you tell me with which component in the Grasshopper I can visualize the rotation axes, as shown in your video? [image] Harald

Martin, Could you send me the Grasshopper file of this hinge, what are you demonstrating? Harald

[image] Harald: But I need that when the panels turn 180 degrees (there was no gap between them). I think you are mis-interpreting that. That hinge is meant to be put into wood doors (or else), where you have to cut/mill the correct “blind” hole for the hinge. You don’t want to have the hin…

What do you need this for?

Soss hinge, not really fully constrained yet, but:
