@Cfytr (Is there a way to tag a member in a post?)

Your work has helped me a lot. Thank you very much for sharing your perfect work for free.

I'm studying the know-how of creating dynamic blocks while separating your dynamic blocks. I don't think I can always ask you for help because new models are being developed frequently by crane manufacturers. I always try to learn your fantastic skills.

Q1. Your block definition is in Russian, so it needs to be translated. Is there a way to translate all the attribute definitions at once?

Q2. I would like to learn CAD skills from you if you allow. Please contact me through my email.

Thank you always.

Q1. The correct translation of technical terms into another language is very complicated. How to translate all attributes at once I do not know. It is better to translate them one after studying their action in the dynamic block. Correct attributes can correct each in 5-10 minutes.< id="BFI_" style="width: 1px; height: 1px; display: none;">
Q2. Ask here, others may also be interested in your questions.

Hello dear. @Cfytr
Attached is the sample file.
A simple block that only uses the main boom section.
Boom combinations aren't important to me, so I made by arranging masts of the same length.

Now, I have two big problems. I hope your help ;(


1. The rotating grip does not follow when extending the boom. (Adjust the boom extension with a look-up formula) 
    I thought I could use a polar point, but.. If I enter a new polar point, the whole formula will fail. (Each configuration has a different reference point during boom rotation.)

2. When the boom angle is not 0 degrees, the array formula fails when executing the look-up formula. (It seems that the arrangement angle is fixed at 0 degrees regardless of the main boom angle.Dead)
   I tried to include the baseline of the mast array in the rotation to solve this problem, but the boom rotation causes an error.


Array (Extended) - Rotation
It only involves two simple mechanisms. It's very confusingCryDeadCryDead


I'll be waiting for you to rescue me
