IHere you can see the parts of my construction – there are three surfaces and three hinges for which I would need to create a movement chain.
I’m also happy to pay via PayPal for a TeamViewer session because I need the functionality of these parts as the first step in a much larger construction in order to then construct the rest of the structure.
Virtually everything depends on this, and I’m stuck.
In the following video, you can see the function of my movements in artistic Japanese origami paper art ;o)
No, just kidding!
I just sent an email to Marika Almgren this minute - should I copy it for you?
This paper animation was just to see how it works. In my actual design, the axes aren’t aligned in X/Y/Z, and the edges of the sheet metal parts’ bends will certainly interfere with each other at first - I have to simulate exactly these things in Bongo in order to then modify and optimize the parts.
I’ve been trying to apply the steps from the tutorials to my design for a long time now, but I haven’t quite made it all the way to the end.
I’m attaching the text I sent to Marika here - but I don’t want two people to have to deal with my stupid beginner problems.
…now I’m going to download your file and get to grips with it, because any kind of work leads to learning. Thanks!
Wanting to be able to do something isn’t always fun ;o)
Well, I’m a bit further along. Due to my limited English skills, I always had German set in my Rhino, and now I’ve realized that this is often more of a hindrance than helpful when it comes to comments from forums and tutorials.
Now, at least, I always find what professionals are answering in the commands.
Anyway, I’ve continued playing with my test file and created the motion chain, where I also adjusted the pivot points to reflect the direction of rotation of the joints.
At the end of the chain, as in the RobotArm tutorial, I also added a point as a “handle” for the movement, and in my case, this is actually set at the TOP! end of the motion curve.
But when I then use the “move to path” component, the point is shot directly to the end of the curve, and when I then start the timeline slider, it just runs backward along the curve.
Why is that? What’s the problem?
I thought because it’s the last element in the chain, it would follow the curve from its resting position like in the tutorial and automatically pull the attached parts along based on their axes and pivot points, or at least give me an error message…???
Concerning your other problems… When installing a connection, at the promt “Select curve. Pick near starting end”, you must click the curve where you want the movement to begin – that is the “starting end” of the curve.
But hey, indeed, you can better mail me at luc@mcneel.com
