Help!: Rotate Fail

[Matanuilover]

i cannot rotate the larger sections of this incomplete robot's arms in LDD 4.0. The image attached shows one of the joints that wont rotate. Can Anyone help me?

You need to make the LXF-file available. I described how in your other post, so check it out.

Once you've done that, I'm sure someone here can help you out.

Alright, i'm back from stupidity rehab, and am still hoping for an answer to my question. I know I can take off parts except the rotate part, then put them back on, but that's a very arduous process.

Your Brickshelf folder says "it is not yet public".

It's strange that it take that long, but if you can make a link directly to the LXF, we can download it.

(in windows 7); Right mouse button, "copy shortcut". And paste the shortcut as a link, so we can download it.

Deeplinks guys...

I think you've basically just got a model which is too complicated for LDD to rotate, it can't figure out which bits you're trying to move. You can see this in the way the red outline (which shows the parts trying to rotate) never completely encompasses the whole leg. Unfortunately rotating large and complex sub assemblies like this is one of LDDs weak points, so you're probably stuck with detaching it, rotating it separatelym then reattaching it. Using the grouping functions can make this slightly less arduous.

As to the flex rods, they aren't flexible in the current release of LDD.

If I understand you correct (the way you want to turn the arm), it is impossible because it is an crossaxle in a crosshole. If you have the pieces you can try it in real life, than you will see why it is impossible.

If you want another piece of the model to move, just forget the above

Legolijntje is right, you can't use a cross axle like that. Replace it with a 4L bar and it will rotate, however for more a robust design you should probably redesign that joint in the first place.

...Rats. I was hoping to avoid that. Thanks anyway!
