Mesh to single NURBS

Mesh to single NURBS

Mesh to single NURBS is a standalone application. This software can convert an open mesh to a single NURBS surface just by clicking one button.

The feature includes:

1. Import .stl file;

2. Convert mesh to a single NURBS surface;

3. Export the surface to .igs file;

4. Controllable precision. The maximum deviation between mesh and surface can be specified;

5. Controllable smoothness. The surface's smoothness can be adjusted by 5 levels;

6. Handle large scale data. Surface control point number can reach 300X300 which allows to fit large scale data.

7. Easy to use. Just click one button to create surface from mesh.

Tutorial to fit a NURBS surface from a mesh

Step 2: Click menu 'Surface->Mesh to single nurbs', the dialog shows, click button 'Apply', wait for a while, a fitted surface will generate. The RESURF message will report that 'Maximum deviation : 1.227468 ; average deviation: 0.159497'.

Step 3: choose Max deviation as 0.5, continue to click Apply button. The surface was updated. Message reports as the following:

"Start surface updating...... this may take several minutes or hours

Surface was updated. max deviation=0.569993 ; average deviation=0.073631

U control # =70, V control # = 70

Surface was updated. max deviation=0.496351 ; average deviation=0.064255

U control # =83, V control # = 80

max deviation=0.496351 average deviation=0.064255

Surface was updated "

Step 4: Close the dialog. Click menu 'View->mode->Hide mesh' to hide the mesh.

Step 5: Click menu 'View->mode->Show surface CPs' to display surface control point mesh.

Step 6: Click menu 'File->save' to save the surface as .igs file.
