Block Problem when exporting as dxf and importing into another program

[ChristopherM]

Hi there perhaps someone here can help me

 

There are some blocks that move to a new location (guessing X=0 Y=0) and I am having trouble figuring which blocks it is. This happens after I export as 2007 dxf and import to another program. so I dont see the wrong Blocks in Autocad which makes things hard to correct

 

I am guessing it has something to do with reference and blocks as I received the file from someone else.

 

Is there a command or a special format to save to so I can see the error and the correct it ?

 

Any help would be much appreciated.

(Image shows where the blocks shows up afterwards but not in AutoCAD 2015)

You can try select all in autocad and see if anything shows up in that area of cad. if so just grab it and delete it. Check to see if any layers are hidden. if so try freezing them. have you tried to purge the drawing. If not give it a shot as well to see if that helps.

No, there is nothing hidden or freezed.

 

It has something to do with nested blocks. Blocks inside a block. So if there is a command to Qselect nested blocks I could easily find them and eXplode them. Or Qselect un-named blocks *1 , *2 and such block... :/
