Why some of 3D Blocks suddenly got disappearing?

[Anonymous]

Hello Experts,

Actually What happened is, I was working on 3D window Designing for two storey house. there were all 7 window blocks with different sizes, and I did first W1. But after the completion of W2, W3 & W4 my first block (W1) Has gone dissapeared from the every place where it placed.  The Again I drew the W1 block. And then completed upto W7 also worked on door designingg also. But suddenly again same block got disappeared from the every place where it taken place.

Actually, I can see the disappeared blocks only if I pointed out  on the place of block.  You can see all the W1 Windows has been disappeared from the every place. There is doubt, Layers for the Windows are open. I designed all the windows with the same layers. So if others appearing, relevant layers absolutely in ON MODE.

PLEASE HELP ME FOR THIS .....

WHAT SHOULD I DO TO GET THAT BLOCK BACK TO BE APPEARED?

(Select > All ) can see the blocks with this commandW1 Block is in the BLOCK LIST.

Hi @Anonymous,

I see that you are visiting as a new member to the AutoCAD forum. Welcome to the Autodesk Community!

Is it possible to share your drawing that contains the blocks? I appreciate all the screen captures and I hope that I can find the reason the first block keeps disappearing.

Hi @Anonymous,

Admittedly this took a while to get fixed.  Your drawing had some AUDIT errors.  YOu also had a lot of stuff all in one file that wasn't really  necessaryu. I copied the 3D portion and moved it to its own file and located the geometry close to 0,0.

I then wblocked out two blocks: W3 3D, and the problem block W1 3D.  I opened each and the display of the W1 3D was not showing any of the geometry.  I used block editor to open the file, checked the layers and then saved the block again.  This allowed the visibility of all the pieces.  I then used DesignCenter to redefine the existing version of the W1 3D blocks with the modified one. I have included my version of the file for your examination.
