Structural Engineering Enhancements in Revit LT 2017

Learn about software improvements for structural engineering and analysis.

• Split columns: To improve workflows and extend usability for fabrication models, the Split Element tool can now split vertical columns at the desired points. See Split Elements.

• Column base attachment: The Attach Top/Base command can now attach structural columns to isolated foundations and footings. Adjustments to the foundation height cause the length of the column to adjust accordingly. See Attach a Column.

• Structural foundation parameters: To achieve consistency and use more recognizable terminology, several reporting parameters have been renamed or changed for wall foundations, isolated foundations, and slab foundations. See Foundations.
  • Isolated foundations: The Offset instance parameter is now Height Offset From Level.
  • Slab foundations: The Default Thickness parameter for filters, tags, and schedules is now Foundation Thickness
  • Elevation reporting: Top/Bottom Elevations parameters are now measured in relation to the Project Base Point.
  • Elevation at Top/Bottom Survey: The Elevation at Top/Bottom Survey parameters for filters, tags, and schedules are measured by the shared Survey Point elevation.
• New parameters for slab documentation: To improve tagging and scheduling of floors, 2 new parameters allow you to specify the default (total) thickness and core thickness of floor types. Use these parameters for schedules and tagging. When one floor layer is set to "variable" and the sub-element has a variable thickness, the parameters display the value "Varies."
