I believe I have a proxy issue. I have ACA 2011. A file from a consultant was modified with aca 2013. they saved down to 2010 and we were able to open file. However, we had to modify a ceiling grid. We could not copy or make a new ceiling grid. It looks like there is an issue with a proxy. I went back into the file and all of the ceiling grids are gone. I type in proxyshow and it did not do anything. is there a proxy object fix from 2013 to 2011?
I went back to the consultant and checked if they have an export to autocad/2011, but all they have 2007. They have save as 2010, but no export.
I have a deadline tonight and do have time for this crap. Have to draw lines for the ceiling grid. please help, if there a fix for this?
