Surface Stitcher

Surface Stitcher

Win64, English

Merge surfaces end-to-end with smooth blending across gaps and transitions; Use SmartPaste to combine surfaces with interior voids.

General Usage Instructions

Surface Stitcher is amazingly simple to use. Commands and workflow considerations are briefly explained below.  Please refer to the online documentation for more information.

Join Surfaces

Join Surfaces will create a new surface. For example, if you are combining surfaces 'A' and 'B', you will get a new surface called 'A + B'. The default style for new surfaces will be used.


SmartPaste enables you to combine a design surface with a copy of existing ground (EG) to produce a final surface which can be blended, and can preserve EG data within voids/interior 'hide' boundaries within the design surface. The basic workflow is (assuming your design is complete enough to merge):

  1. Create a new surface FinishedGrade (or similar)
  2. Paste EG into FinishedGrade to effectively create a copy of EG.
  3. Run SmartPaste
  4. Select FinishedGrade as the 'target' surface and your design surface as the 'paste' surface
  5. Configure options and press OK.
