From your illustration, it seems like the hinge is off center. (to the rotating axis).
-Which will hinder the rotation.
The hinge is added to the columns, but they are apparently not lined up to fit the line/center of rotation. (sorry for my English…)
But it would be much better for the problem solving if you could upload your model. Thanks
I found two things to help me in the resolution of my issues:
“drill” a hole in a 3D object is not “understood” as an empty space by SP.
To create a hole, we must group objects in order to design the hole.
by using the “Debug” option, I realized that the crank is not viewed by SP as a wire but as a cube (an envelope all around the crank). So I resolved my problem by setting the state of the columns to “ignore”.
Now the crank and the circle move freely.
I will continue with the rest of the project and of course, I will keep you inform!
Been kind of busy here in this heatwave, but/and would like to try your model.
Maybe you could upload the file here for everybody?Thanks.
(instead of signing up for Dropbox…)
Wish I had more time for all this fun stuff!
Cheers
I worked all the day on the project and no way to design a real case!
what I learned today:
if the model is too small, there is no physical interaction (may be due to tiny numbers in the formulas); so I multiply the size of the whirligig by 100
if you want to attach 2 joints to the same 3D object,
joint 1 + Group 3D Object
joint 1 + Define parent
Explore the new 3D object group, clik on the 3D object to isolate it
joint 2 + Group 3D Object inside the first group
joint 2 + Define parent
Sorry but I don’t know how to attach a file directly in the forum, so I used Drop Box again
That is a charming whirligig!
Well you can upload here:
-or drag and drop.
Several years since I tried SP so I don’t remember much…
It was lots of work to learn. That I remember
Maybe this model to study is close to your project?
I finally solved my problems with the whirligig.
What I learned today (stay positive )
It’s very important to set the joint very precisely (an offset can have a huge impact)
when nothing works, set a name to the joints, you can play manually the animation … and keep calm
Check examples on the warehouse … if you don’t find exaclty your solution, at least you will see people doing things really more complex that what you are trying to achieve
It could be nice to have a dedicated forum for SP; there are so many things that we can do (… and so little documentation :()
I hope that a new 64 bits will come soon (now I have to work with SU 8 with SP and SU 2015 for my other projects) - No way to install on the same computer SU 2015 32 and 64 bits
Hi!
Thanks for model.
-I did find out how to download from Dropbox though ( Dooh, didn’t have to sign up)
So I ended up spending time on SP in my weekend too…
-and learned something too, I think…
Your solution to transferring the red/blue plane rotation to the green/blue plane is quite interesting and innovative.
Well, I wish I had more time right now, but must go to work today.
