3d autocad problem please help

[Anonymous]

I am designing mechanical machines on 3d AutoCAD. The problem is when I close the program and open it again to complete the design I find that the parts of the machine some times separated from each other especially if you i was assemble these parts in a package ( group) and This cost me more effort to bring the parts back to their proper location how can i solve this problem

Dynamic Blocks are what this forum covers.  It doesn't sound like you are using dynamic blocks.

Hi and Welcome to AutoCAD Forum,

would you please try to install the latest service packs that relate to your CAD version and see if any changes. >> Click <<

Hi,

When reading your question you use the term assemble. I suppose you are using AutoCad and not Fusion360 or Inventor (where there's a thing such as "Assembly's" and which are both excellent programs for designing machines and machining components.

In case you are using groups, have you tried setting your _PICKSTYLE to 1?

Thank you for your attention
i have installed the latest service packs without benefits

this two pic the first before close the program 

the second after close and open it again 

after opened All the pieces were scattered12

could you please share your .dwg file with us?

If we could replicate the behaviour than we might have a better chance to figure out what is wrong.

First I exploded your group, moved the parts to the correct position and created a new group. Than save, close, reopen - all is ok.

A second try: I made your group selectable, moved ( the parts to their correct position, made the group deselectable. Then again save, close, reopen - again all is well.

This means, I can't see any errors nor problems. I guess you must tell us more... (what you did exaclty). Maybe you can try yourselve what happens if you explode your group and create a new one (?)

Sorry, I tried it again and can not replicate the behavior you described.

What do you mean with " with out using group order"?

Please tell us, how you use the group command exactly. In such a manner that we can it reconstruct here.

Attached a screencast what I do:
https://autode.sk/2raDVlR
- assuming there are any 3D-Solids
- move the solids to a whished position  to get an assembly
- group all items of the "assembly"
- do any modifying with the group (move, rotate, 3Drotate, ...)
- save and close the drawing
- reopen the drawing: all is fine, no problems, no one item "flies away".

And now tell us what you do and what happens.
