How to Reset/purge attributes with Field link

[timothy.d.vu]

I accidentally broke a field link for an attribute in my block. The only way to relink the field is to create a new attribute with a new name and redo the Field. 

In my example, I need to show northing/easting and some clients prefer decimal feet, so i create a formula to divide the position by 12. I accidentally overwrote it by putting a dash in the box, is there a way to reset the field without having to delete the attribute, and creating a new attribute.

No need to create new attribute just to create a Field. In the edit attribute dialogue click the attribute you want to create the Field then inside the edit value box remove the “-“ then right mouse click and select Field. Now you’re back to where you want to enter your original formula

It doesnt work when I insert field from model space. the blockplaceholder is only accessible in the block editor. 

The problem I have is that if I break the field, the only way to get the formula I need is to create a new attribute with a different name. Editing the attribute and trying to recreate the formula again doesnt work, the formula wont come back.  If i delete the attribute with the broken field, and re-create the attribute with the same name, the formula wont work. It's like the old attribute with the old definition is still there.

Perhaps better way to sho what you’re doing is upload a dwg with a block attribute that has a working Field vs another dwg that has the same block attribute that is missing the field

Go the way you know, just a bit more smart:

RENAME the Attdef tag in BEDIT, run attsync

RENAME the Attdef tag back and run attsync again.

In fact the same think, just a bit smarter

Renaming the attribute and than naming it back worked like a charm.
