New in Surface Workflows

Learn about enhancements to surface workflows.

New in 2025.2

Surface editing with triangles or points enabled

• Added support to automatically enable component display when adding a surface line or adding/moving a surface point.

New in 2025.1

• Surface editing command optimisation
  • Appropriate style display component is activated when using surface editing commands. For example, swapping surface triangle edges will display triangles in the surface style automatically.

    This is enabled by default, but the Automatic Component Visibility during Surface Editing can be disabled in the Edit Feature Settings – Surface dialogue box under Surface Defaults.

• Sorting the Volumes Dashboard enhancements
  • Added the ability to sort alphabetically.
  • Added the ability to keep the last sorted column order if a drawing is saved and reopened.
  • Added the ability to export a Cut/Fill Report using the column order as sorted in Civil 3D.

New in 2025

• Added a reduced surface level of detail to improve performance when working in drawings with large surfaces. For more information, see Modify the Level of Detail of Surfaces.
  • Contextual commands to change the surface level of detail added to Prospector tree, in canvas, and the ribbon.
  • Default setting for Reduced Surface Level of Detail added to the Edit Feature Settings - Surface dialog box.
  • Level of detail commands are available from the command line.
    • AllSurfaceLODLow
    • AllSurfaceLODHigh
    • SurfaceLODLow
    • SurfaceLODHigh
• Performance improvements when saving surface MMS files.
  • The MMS file will not update if there is no surface geometry change.
  • The dref surface will not update when the host drawing is saved.
• Performance improvements during multithreaded contour regeneration on both TIN and Grid surfaces.
  • Opening Drawings. When the drawing contains surfaces styles using contours display component
  • Surface Editing. When the drawing contains surfaces styles using contours display component
  • Changing Surface Style. When the drawing contains surfaces styles using contours display component
  • Surface Creation. When commands trigger the computation of contours.
  • Contour Extraction from Surface.
• General performance improvements when working with surfaces.
  • Improved Zoom/Pan performance for when the level of detail mode is off in Conceptual/GSF mode (shaded, and shaded with Edge).
  • Surface will not regenerate if there is no surface geometry change (such as the changing name or description of a surface in the surface properties dialog box.
