v2.1.0 / MacOS Yosemite
Hello,
Following your advice I transfered entities C (the colored ones on the right side
of the attached file) to drawing AB that I want to update using C new dimensions.

1-  both AB and C drawings were set to 1:1 scale in 'print preview'
     (I don't know why but it helps keeping C dimensions values the same after transfer)
2-  added an 'importation' layer on the AB drawing stack
3-  draw a cross target on the 'importation' layer
4-  put layer-0 in non-erasable status
5-  used cmd-c / cmd-v
5-  landed entities C on the cross target (the importation layer was activated only)
6-  entities avoided the importation layer, they all went to layer-0 !
7-  dimensions were 1:1 but under rather large and .0000 precision generic characters.
8-  clicking 'current drawing prefs' OK, dimensions stretched back to their original size and style
9-  whatever I do, Select all  then Explode in  Modify or Block,
     there is no more access to the entities.

The drawing seems to be a dead image.  Only the 90° angle of a contersunk hole
is still active at the upper left of the AB contrribution. Unfortunate as it is, step (6)
is not a game stopper but (9) is.
Would you give me the miraculous hidden key to continue ?
