Down Save Revit Models
Paul Crickard hates that Revit will not allow him to open a 2011 model in 2010. When upgrading to 2011, his office decided to only move certain projects over and leave others. They took in to account the fact that we could not down save and once They were in 2011 they were stuck in 2011.
There is a workaround! If you really need to open a model from a later version of Revit you can — by using IFC.
WARNING: You will lose information. Your walls, windows, doors, and some other elements will be safe, but the model will not be 100% complete — depending on how detailed it is.
To see what will export, go to EXPORT>OPTIONS>IFC OPTIONS
As you can see, Area Tags will not export by default. If you are familiar with the IFC tags you can export objects that are currently not exporting by specifying what tag should be used in the IFC.
Export your model to IFC. Voila! you now have a text file (.IFC) that should look as follows.
From an earlier version of Revit click R>OPEN>IFC and select the file. Now you have a 2011 model in 2010 or 2009. This is also a good way to get your file to many other programs.
DISCLAIMER: Paul Crickard does not recommend using this as a way to work on a daily basis. This tip is for those times when it is absolutely necessary to go between two different version of Revit. You should talk with all parties involved in a project and decide on a version before beginning your project.
