Upgrading Revit Projects
September 25, 2020 Leave a comment
Many of our clients hesitate to upgrade their Revit projects to the latest release. There are many reasons for the delay, cost, project member concerns, time or even loss of work. Microsol Resources can help prepare your team for this necessary upgrade. There are many benefits to upgrade to the latest version of Revit. Security, stability and new features are enough for me to want to upgrade. I will include basic steps and recommendations.
Host Models vs Linked Models
It’s best to upgrade the linked Revit projects before upgrading the host. if not, the host model will temporarily upgrade the links in order to load them in the upgraded host model. I open the host, unload all the links save it, then upgrade. Be sure to check the paths of the other linked elements once upgraded and reload. Instruct all team members to synchronize with central, relinquish all elements, and close their local copies of the central model. Backup the models and archive. It’s recommended to audit the model at this time. Why not preform the Revit project maintenance as outlined in my blog; Revit Project Maintenance Guidelines.
Upgrading Beyond 2017
The most important aspect to understand when upgrading a project is, what will change. In most cases nothing, but when our clients upgraded to Revit 2017, we noticed text problems, correction, changes. “The method for measuring text size has changed, so that the Text Size parameter more accurately represents the height of a capital letter (similar to AutoCAD).” In Revit 2016 and earlier, text size is measured by the ascender height – the height of lower case letter ‘h.’ In Revit 2017 size is measured by the cap height – the height of the capital letter ‘M.’

After upgrading a model, review all views and sheets to verify the changes to your text instances. Note: Be sure that the proper fonts are installed when opening an upgraded model. Substituted fonts further will change text due to the font sizing changes. I recommend Bluebeam for a before and after, full set comparison. This way no changes that occur as a result of the upgrade will be missed.
