Pendant rotation problems
Accepted solution
Hi @Anonymous
Thanks for posting the screencasts! I was able to have a look at your design this afternoon and figured out a solution that I think may work for you.
To accomplish this, I had to make quite a few edits to your original design file. Here are the key points:
- Firstly, I had to create the pins as new bodies instead of joining them to the base assembly while executing the revolve command to make them. This allowed me to turn them into components later and use joints. In this process I made some edits to the design timeline - please let me know if you would like more details on that.
- I had to open the pins in a new file, create joint origins based off sketch geometry (which I copy/pasted in from the sketch defining the pendant bodies geometry), and then insert the pins into the pendant body design. I broke the link and them copied the first instance of the pin I inserted to add in the other three. You can see these joint origins in the attached file "JW PINV@v1."
- From there, I used the joint origins created in the individual pin files to the center of the base. This allowed me to create revolute joints. While placing each instance in, I was careful to keep them in a straight line for later reference. I grounded the base (pendant body) as well.
- After creating the revolute joints, I used parameters to define the rotation of each of the pins. Because I aligned all the joints along the same axis when inserting them, that line serves as a zero degree reference. You can now enter angular values to position each pin, as the pin will rotate clockwise from its baseline the specified angle in the parameter dialogue box. I have illustrated this in the screencast below:
Please let me know if you have any questions or need to see parts of this process in more detail and I can create screencasts illustrating more of this process - it was a tricky one and I didn't want to leave too long a video! I've attached my full assembly file and my pin design file to this post - you may be able to look through how things are set up in those to get a good idea of how to approach this problem.
Kind Regards,
