Help with LDD/rotating a whole object

[tripletschiee]

Hi guys,

i despair!

Can some of you pros help me rotating that crane into an "upstrait" position. It should stay folded, but should "stand straight" on the turntable. The turntabel should be the lowest part.

How can help me?

1000 Thanks!

You simply have flaws in your LDD design: somewhere in the last 3rd section (the one connected as last part) is something wrong: probably it just sit in the air pretending it is connected to the other parts cos when I deleted it then it could be rotated...I am further inspecting it but as your design is quite a mess of a technic bricks it may take a little (if at all)

OK, here you go: I had to remove the inner part of the 3rd section (the black one) cos it was NOT CONNECTED TO ANYTHING - it was just sitting there in the air thus rotating did not work - once removed it is working OK...I rotated it as you wanted (see included .lxf file + I put that inner black part outside your model, but if I were you I would rather really rethink that design unless it is some real LEGO model that you are trying to recreate, of course EDIT: I just realized it is a LEGO set).

BTW: I am suggesting you to really rewriting your model cos it has so many not needed bricks that only making whole model less "readable" when searching for possible flaws + many of those connection you made there have no real effect in LDD...

There's an even easier way, which involves LDD's "snapping" ability. It also preserves the relative position of the extending section of the crane arm.

Place a technic brick or beam anywhere in the scene, then select the crane through the groups. There's a Dark Stone Grey 3M axle with knob on the side of the crane which will be used as our "snap" point - because it is inserted orthagonally, it will correct the orientation of the whole structure once it connects to any of the holes on the brick / beam placed earlier.

Wow! First of all: THANK YOU so much for your support!

I have to say, this is my first model I am drawing with LDD, so I am not that deep into that application sofar.

I want to use LDD as a sort of an archive for my models. I have build this crane already with real bricks and now want to recreate it in LDD to have it archived just in case I need to disassemble the crane for some other project again.

Now to my laws:

as the two inner (black) sections of the crane are just sliding in each other and the outer (yellow) section, there could be no "real" connection. Each inner section is just stuck in the outer section and only held in place by a black 12T double bevel gear. Is i that, waht you mean "it is just sitting in the air", bublibe?

Concerning my "unnesseccary connections": in LDD you're right, but in real life, these conncetions made the crane remarkable stiffer.

Regards,

Gerhard

No problem + yes, I understand you fully (you were simply creating in LDD 1:1 copy of your real life brick model) - on the other hand you just need to know that real bricks vs. LDD models are "a bit" different things, for example: in LDD there may not be any "open connection" if you want to bend/turn such build cos LDD is not able rotate stuff that has such connections in it (it needs to be all connected for rotation to work). therefore you always have to make some changes in such LDD builds (or at leeast make them temporarily just to rotate your stuff and return it back once you have done it).

Gentlemen, I did what you suggested: i rebuild the whole stuff from scratch. And now it worked out without any problems!

Maybe, as I copied the basis of my (modified) crane from some source here in the forum, I messed something up.

Now I am satisfied!

Many thanks once again.

.....

In real life, the crane folds even a little more, as the whole stuff has some play.

Gerhard
