@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.  ) 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 confusing  I'll be waiting for you to rescue me
