Can't change to dwg - can someone look at this file

I was able to down load it and I compressed it all options then exported to dwg.. crashed at 94%

reopened dgn ref attached it to clean new  empty DWG via mstn then merged into DWG ( not recommended  but save as didnt work)

it created dwg on screen fine.. saved and tried to open in Acad.2015. file empty no graphics didnt try any acad repair file features as I'm not  100 up with acad just wanted to see if acad recognised it.. tried to open with msnt crashed at 94 %

There are or must be some elements that mstn doesnt know how to convert to DWG...  last time this happened to me I found that  XM was more forgiving and did convert with out crashes and the converted file could be opened  but no idea as to what was missed in conversion... xm uses a different  recipe to convert  where as v8i uses realDWG.. so if you have access to XM use it for the conversion to DWG...

In my experience this problem most often happened to me  when someone else copy pasted from a dwg ref file patterning data  into a DGN and when you try to export the dgn back to dwg Mstn it doesnt  know how to convert a dwg pattern info its expecting  DGN info  this is my  humble lay person interpretation I know it doesn't actually work that way  but its a good way to visualise it...

Also the file was very slow to load in msnt as a dgn and a lot of rasters were missing...  its just a floor plan so why are there meshes, even piano keyboard described as   a mesh? why not an array or a cell?

Thank you for trying this

- this is a 2d maked from 3d model ( you try delete meshes ? )
- i don't know but maybe because as i know - the base was in Autocad students version or something like this - so maybe this is a problem ?

yes as I said before I had probs when people copy pasted patterning from acad dwg to dgn ... when I had axiom tools at work  the dgn repair tool often found these and helped me  fix them  by removing them or exploding them ...

again as I said before if you try and open with XM and do save as acad it will most likely work  for you...
