Transoft Solutions
KeySurfaceFix allows you to find and repair holes in an Autodesk® Civil 3D® surface so that your surface more accurately reflects the existing site and design proposals.

General Usage Instructions

KeySurfaceFix, from Transoft Solutions (UK) Ltd, is an application for Civil 3D that will repair holes in a surface, or surfaces, in the current drawing.  

How to use KeySurfaceFix to Repair a Surface

Using Civil 3D, open the drawing with the surface containing holes.

Open KeySurfaceFix from the Transoft Solutions Apps >Surface Utilities>Surface Repair Palette (keyboard shortcut, KSRP).

This should scan the models and, on the Manage Holes tab, list the surfaces in the drawing and any holes found for each selected surface.

  • Under Holes, check/uncheck each hole you wish to repair individually or, under Surfaces, check the box next to a surface to select all holes for the selected surface.
  • To zoom to a surface in the drawing, select the surface name, right-mouse click and pick Go To from the menu.
  • To zoom to a hole within a surface, select the hole(s), right-mouse click and pick Go To from the menu.
  • Pick REPAIR SELECTED to begin the process of repairing the selected holes. 


Note: When repairing large or complex holes, it may only be possible to partly repair them in a single operation and so holes may still exist in the surface. It is good practice to re-scan the model to confirm that all holes have been repaired by selecting Scan All Surfaces for Holes, from the right-mouse menu under Surfaces.
