Architectural Enhancements

• Wall joins: To simplify the control of wall joins in a plan view, you can now select multiple intersected wall joins with a single click, and choose to allow or disallow joins on all the selected walls with a single click. If you choose to allow joins, you can then specify a Display option (Clean Join, Don't Clean Join, Use View Setting). See Specify Wall Join Cleanup Options.
• IFC references and phases: Use existing geometry in a linked IFC model as references for dimensions, alignment, snapping, and hosting of some face-based families in the Revit LT model. When you link an IFC file, its elements are assigned to a default phase. Before using IFC Import, Link, or Export, go to Autodesk Exchange Apps for Autodesk Revit and download the latest edition of IFC for Autodesk® Revit LT™ to take advantage of up-to-date improvements.
• Shaft openings: To streamline the creation of a shaft opening, the Base Constraint value now defaults to the level of the current activated plan view. (See Cut a Shaft Opening.) The instance properties have also been reordered to be consistent with families with similar properties: Base Constraint, Base Offset, Top Constraint, Unconnected Height, and Top Offset.
• Site design: Performance enhancements result in improved edit and regeneration times for complex toposurfaces, subregions, and building pads.
• Perspective views: Certain modeling capabilities are now available in perspective views: (See Work in a Perspective View.)
  • Editing tools: Move, Align, Pin, Unpin.
  • Reset Target tool: Restores the position of the camera target to the center of the field of view.
  • Toggle between the perspective and parallel representations of the 3D view.
• Reference other view: To search the list of available views for reference, enter keywords to locate the desired view. This feature is available when you are creating views for callouts, sections, elevations, and details, and you select the Reference Other View option (or modify a reference view). Also note that the Reference Other View option now displays on the Reference panel of the ribbon instead of the Options Bar. See Reference a Drafting View and Search.
• Reveal constraints: To see all dimension constraints and alignment constraints in a view, use the Reveal Constraints mode, available on the View Control Bar. See Reveal Constraints.
• View updates: Performance enhancements result in faster updates to views that contain multiple instances of families.
• Revit links: Further enhancements result in improved performance for cases where Revit link instances are loaded but not visible in the view (such as when they are outside the crop region).
• PDF Export enhancements:
  • Share your designs as electronic PDF files with automatically linked views and sheets. Each view tag in the PDF file is a hyperlink. Click a hyperlink to jump to that view or sheet in the PDF file. See About Printing to PDF.
  • Avoid lengthy or unintended print jobs. If you choose to print multiple views and sheets to individual PDF files, you cannot cancel the print job once it starts. A new message warns you of this issue and allows you to cancel the print job before it starts. Instead, consider printing the views and sheets to a single PDF file. See Troubleshooting: Printing Views and Sheets.
• Schedules: To easily add a data row to a schedule, use the Insert Data Row tool, which is available directly on the Rows panel instead of within the Insert drop-down. The new position of this tool makes it easier to add a data row to a room schedule, area schedule, key schedule, space schedule, or sheet list. See About Modifying Schedules.
• Select host for tags: To specify the host element for a tag, select the tag and use the Select Host tool. See Select the Host for a Tag.
• Annotate stair treads and risers: To streamline the process of adding number annotations to treads or risers in a component stair run, specify default properties before placing the annotation. These default property values persist for tread/riser annotations added to the model. See Number Stair Treads and Risers.
• Thin lines: To improve consistency between Revit LT sessions, when you use the Thin Lines tool, the setting is stored in the Revit.ini file. When you launch Revit, the stored Thin Lines setting is used as the default. See Graphics Settings in Revit.ini.
• Export Models with Lines that Coincide: When exporting a Revit model to a CAD format, you can decide whether to maintain model lines that coincide with other lines in the same space. See About Exporting Models with Lines that Coincide.

Structural Enhancements

• Snap to model lines for structural elements: To expedite and improve the modeling workflows, the following snapping enhancements are available for structural elements. See Snaps.
  • You can snap to linked or imported (non-exploded) CAD drawings.
  • Similar to the behaviors when placing structural walls and slabs, all structural elements now snap to the geometry of imported drawings.
  • 3D snapping has been enhanced.
  • Snaps such as nearest, endpoint, and midpoints are available when defining structural elements along model lines.
  • Additional snap locations are available along model lines for structural framing elements, structural columns, trusses, and isolated foundations.
  • When you place non-hosted loads, you can now snap to model lines.
  You can snap to linked or imported (non-exploded) CAD drawings.
• Structural framing orientation: When refining your model, you can flip structural framing elements and maintain joins, as well as setback, geometry, and justification modifications. See About Structural Framing Orientation.

Multi-Disciplinary Enhancements

• Search: To quickly find the content you need, use the new search feature in the Type Selector or in drop-down lists. Click the Type Selector or a value field in the Properties palette or a dialog table, and enter keywords to search for. See Search.
• File upgrades: To help you understand the consequences of file upgrades, new dialogs indicate the release of a file and the release to which it will be upgraded. In many cases, you have the opportunity to cancel the upgrade before it completes. See About Opening Models that Require an Upgrade.
• Edit/load a family: To close the family automatically after it is loaded into a project, use the Load into Project and Close tool in the Family Editor. See Load the Current Family into a Project.
• Properties palette: Keep your context in the Properties palette when you scroll, select a property, and then click outside the palette. This behavior can be helpful, for example, if you are selecting different family instances in the model to compare their properties.
• Pin/Unpin icons: To determine whether an element has a relationship with a host system, select the element to see its Pin/Unpin tool icon. A different set of pin/unpin images () is used in the drawing area to indicate a relationship with a host, such as a curtain wall panel or a beam in a beam system. The behavior of the pin has not changed (clicking it still allows you to override the properties for the element), but the subtle difference (small link in the image) adds a visual indicator that this pin is different than the standard pin that locks an element in position. The Pin/Unpin tool icons on the ribbon have not changed. See Unpin Elements.
• Import/link position: To streamline the process of inserting a Revit model or a CAD file, the default positioning is now Auto - Origin to Origin. If you change the default, the option you select for Positioning becomes the default for the current Revit session. The software remembers one default option for Revit models and another default option for CAD files. See Import and Link Options.
