The Merge/Reapproximate Surfaces option allows you to merge two surfaces at their seam. If you select NURBS data surfaces, you will be given the option to convert them into faceted data before merging.
The options for re-approximating surfaces will create one surface from a set of selected surfaces while re-approximating the surface boundaries to a given tolerance. This is useful for several operations, including the following:
To clean up surface data by creating a re-approximated surface from multiple segmented surfaces.
To clean up more complicated geometric formats into a more simple surface data structure that is easier to manipulate. For example, some CAD systems will represent a four sided surface as a trimmed plane. Re-approximation will create a ruled surface to replace this.
To convert a faceted surface representation to a Bspline representation if the boundaries of the faceted surface is well defined.
Note: To perform this operation, Build Topology is necessary.
There are four options to merge surfaces:
Merge Surfaces
Merges two surfaces that are separated by a gap within the specified tolerance.
Reapproximate selected surface(s)
Re-approximates the selected surfaces into one surface.
Reapproximate selected surface(s) bounded by curve(s)
Re-approximates two adjacent surfaces that are joined by a common curve.
Reapproximate selected surface(s) bounded by hull
Re-approximates surfaces that are bounded by a hull.
Faceted only
Allows you to select faceted surfaces only.
Reapproximate each surface
Allows you to choose the automated Quiet option, or the Confirm option that will display the merged surface before creating it.
Faceted only
Allows you to select faceted surfaces only.
