Convert Multiple Surfaces To One Smooth Surface

Hello dear engineers
I have a 3D scanned part with iges format
There is a lot of surfaces on it , that I want to combine them to one smooth surface
Combining is so easy but I want to remove edges between surfaces .

I'm sorry, but what are you trying to achieve exactly?

Surface patches are part of complex surface design. If you're unhappy with the continuity between patches then you should probably use some defining geometry and rebuild the surfaces. You will need to create other patches along the way, so you'll need to know what continuity you'd like to achieve and the amount of deviation from the original model that's acceptable, in both your patch(es) and new surfaces.

Or perhaps turn shading without edges on... if it's simply something that's bothering you graphically.

The options I can think of are:
1. Use some program to remap the topology of the surfaces. Most scanning\meshing software should allow this to be controlled.
2. Sometimes the mesh or points can be "smoothed" or simplified a bit before creating a surface body. The simpler the mesh, the fewer the surfaces in the end (usually).
3. To truly control the topology of the model, you need to remodel it in a CAD program. Use the existing surface as a reference, then create a new solid or surface body over it.
Some programs like Control, and DesignX will show a deviation map so you can see how closely your CAD data matches the surface data.
I have a project uploaded that shows an example: STL to NURBS - Reverse Engineer Scan Data

Copy the face and then use feature Stitch
