Some new and changed features of Revit 2017 result in certain behaviors for upgraded models. Review this information before upgrading your models.
Text Measurement
The method for measuring text size is changed so that the Text Size parameter more accurately represents the height of a capital letter (similar to AutoCAD). Previously, Revit measured the size of text from the font baseline to the ascender line. Since most characters do not extend to the ascender line, physically measuring the font may not have produced expected results.
The size of text now reports using the cap height, which measures from the baseline to the top of a capital letter M. It is important to note that many Asian characters are somewhat taller than the capital letter M, so these characters appear taller than the Text Size parameter value for Western fonts. Adjust the Text Size parameter to make these characters the desired height.
This change affects all text in Revit. After upgrading a model, please review all views and sheets to verify the changes to your text instances.
- The editor can support font sizes from 1 point to 1638 points. For Arial, these font sizes translate to approximately 0.1" to 16.3" or 0.3 mm to 413.6 mm.
- The text note also has a maximum width of 84" or 2135 mm.
Toposurfaces
The behavior of additional contours is improved to adhere to the Additional Contours specifications in the Site Settings dialog.
Previously, additional contours started at the bottom of the toposurface regardless of the Start or Stop settings. As a result, when you upgrade a model, existing toposurface objects are not regenerated; the post-updated model looks the same.
However, the first time the toposurface regenerates, such as when you edit the boundary or perform other related operations, Revit uses the new contour behavior. If desired, you can adjust the start range for the Additional Contours settings to achieve the same visual effect as the pre-updated model. See Define Site Settings.
Keynote Legends
The behavior of keynote legends is improved. When a keynote legend is set to By Sheet, Revit takes into account whether a keynote is visible in the view as a result of View Range settings, Design Option settings, or Depth Clipping/Far Clipping settings.
Previously, keynote legends listed keynotes that were not in the view because they were outside the view range, in a different design option than the one currently displayed in the view, or outside the view's Depth Clipping/Far Clipping range.
When you upgrade models that have keynote legends By Sheet, ensure that they display correctly. Note that a legend may have changed because it does not display keynotes that are not within the view range, depth clipping, or design option of the views on the sheet. See About Keynote Legends.
Railings
Enhancements to railings required changes to existing functionality. When you upgrade a model, railings hosted by floors will likely be slightly altered, as will railings sketched outside a host.
After upgrade, inspect all views to verify changes to railings.
Structural Connections
The new structural connection feature introduced in Autodesk Revit 2017 does not overwrite legacy connection elements in upgraded models. Older connections will need to be replaced with the generic or add-in connections to be accessed by the new tools. See Structural Connections.
Render Settings
When you upgrade models, render settings defined for the NVIDIA mental ray engine are mapped to Autodesk Raytracer settings to achieve a consistent rendering output. Settings specified in the model for the Autodesk Raytracer rendering engine are not maintained during upgrade.
You must define these settings upgrading a model to Autodesk Revit 2017. See Upgrade Mapping for Render Settings.
Family Categories for MEP Fabrication
When you upgrade Autodesk Revit 2016 models to Autodesk Revit 2017, the model category for fabrication parts changes from a single Fabrication Parts category to separate categories for MEP Fabrication Ductwork, MEP Fabrication Pipework, MEP Fabrication Containment, and MEP Fabrication Hangers.
Existing fabrication parts schedules that contain ductwork are reused for MEP Fabrication Ductwork. Pipework, containment, and hangers in those schedules have been removed.
Existing tags for duct are reused as ductwork tags. Pipework, containment, and hangers tags have been removed.
