The information in this article applies to:
I have a number of older plans I created using 3D Home Architect® Deluxe, Chief Architect 9.5 or earlier, or Home Designer 6.0 or earlier. Will Chief Architect or Home Designer software open these older plans with the .pl# file extensions?
I receive a warning message of:
"This version of Chief Architect can only read plans written by Chief Architect Version 10 or later, or Home Designer 7.0 or later."
"This version of Chief Architect can only read plans written by Chief Architect 97 or later, Home Designer 6.0 or later, or 3D Home Architect 3.0 or 4.0"
How can I resolve this warning?
Chief Architect X9 and Home Designer 2018 and newer versions can open the .plan and .layout* files from prior versions.
*.layout files not compatible with Home Designer Architectural, Home Designer Suite, Home Designer Interiors, or Home Designer Essentials.
If you still have an older version of Chief Architect or Home Designer running on a supported operating system, then you may open these .pl# or .la# files in that version, save them as .plan files, and then open them in the newer version of the software.
The Chief Architect X8 and Home Designer 2017 and earlier versions would support opening drawings only from Chief Architect '97 (version 5.0) or newer, but plans created in Chief Architect version 4.0 and earlier could not be opened directly.
Home Designer 2017 and earlier versions would support opening drawings from 3D Home Architect® Deluxe versions 3.0 and 4.0 only.
Please bear in mind that after an older version file has been opened in the newer program, the plan will not appear exactly as it did when it was initially created.
For example, textures and 3D symbol objects from the discontinued version will not be recognized. There will be missing electrical and other object defaults, and warning messages will display on opening the file, as well as taking 3D camera views, regarding these objects.
While you could try to replace all of the missing textures, objects, and defaults using materials and symbols from your current Home Designer Library Browser, the real advantage of being able to view the older file is to reference dimensions and object placement.
In order to have all of the capabilities available in a current version plan, such as Wall Types and other features, recreating the plan in the current version of Chief Architect will be necessary.
