Architect template modification

[Anonymous]

Hello,

 Someone helped me modify the standard architecture dwt which comes with c3d 2016 but he had a later version then me which caused me not to open the file.

I tried using the recommended software to fix it but the process just hangs and does not complete. I am not to good in this stuff and appreciate if someone has some time to fix this.

Thanks

There is nothing you or anyone else can do about it: once you edit in 2018 or newer software all the content gets locked out of your older 2016 version.

You will need to start over, only versions 2013-2017 can edit your file so that you can still use it.
