Hi!
Is there possible to convert a Autocad Architecture 2018 to Autocad Architecture 2017/2013?
I have been working in 2018 with the belief that you can save it to 2017/2013 version (like you can in the original Autocad). But when you have an earlier version (2017) and it wont open.
Is there a way to solve this?
AEC objects (Walls, Doors, etc.) cannot be saved back to a previous file format in any usable form.
You can use SAVEAS to save the file to the 2013 file format, but the AEC objects will remain in the "future" format (2018). Their presence will disable the AEC commands in AutoCAD Architecture 2017 (through 2013). If you enable proxy graphics, you may be able to see the AEC objects, but you will not be able to edit them.
You can use the AECEXPORTTOAUTOCAD2013 command to export the file back to the 2013 file format, but that will explode the AEC objects to plain AutoCAD linework, based on the active display representations at the time of the export. This works if the end user only needs a "background" over which to draw their work; there will not be any Walls, Doors, etc., just lines, arcs and hatch.
