This was very helpful! Thank you
I have a question in line with Rob's request. i'm also working with cranes (tower cranes) and i started learning dynamic blocks recently. Is there a way i can rotate the jib but with it also stretch and rotate the pendant lines as i have noted below.

That should be possible. Post your block so I (or some other) can demonstrate a way ...

Attached a simplified schematic solution.

What were your steps,
What shall happen with the both "lines" (marked with ???). They make no sense when the jib rotates (?).

The two lines will in question will rotate the same as the pendant lines.
For my fun only, how I'd do that.

In my suggestions above I found a (small ?) mistake. 😞
It is repaired in the attached improved version.

Do you have any idea why this is?
You moved the complete crane geometry in y-direction, but the stretch frames remain on their initial (and now wrong) position.
You must repair all the stretch and polar stretch actions. (one by one: Right click -> modify selection set - pick a correct stretch frame).
[EDIT:] Or see post #14 ...

Another way:
To move the geometry upwards you must not use the MOVE command. Instead use the STRETCH command: Select all geometry including all actions completely inside a selection frame. Before you must have set BACTIONBARMODE to 0 (to be able to grab the actions).
Good luck

In the meantime I added some small bug fixes:
If you decide to use this version as base for the next modifications (adding the tower ...) I'd suggest, first to use the stretch command (in the block editor) to place the geometry to the needed new location (moved upwards) and then repeat the work to add the tower.
Of course you also can ignore these small inaccuracies (they are only visible for large angles, but also for small angles they exist. I hate such botches 😉 ).

Based on your example here again the main principle how you can solve such issues.
