How to export all edges of a model as wireframe curves to an IGES file.
Solution
1. EDIT THE "UGII_BASE_DIR\IGES\igesexport.def" FILE
a. Open the "UGII_BASE_DIR\IGES\igesexport.def" file in a text editor.
b. Add the option, 'All Solid Edges', to the UGI_CURVE_MASK line so it
looks like the entry below:
UGI_CURVE_MASK = Points,Lines,Arcs,Conics,Rational B-Spline
Curves,Solid Edges on Drawings,All Solid Edges
c. Remove all the values for the UGI_SURF_MASK and UGI_SOLID_MASK options:
UGI_SURF_MASK =
UGI_SOLID_MASK =
d. 'Save As' this file to UGII_BASE_DIR\IGES\igesexport_wireframe.def
2. USE THIS SETTINGS FILE WHEN EXPORTING
a. In NX, select 'File-->Export-->IGES'.
b. On the 'Files' tab:
Export From = Display Part
c. Browse and set the option 'Settings File Load From' to the
igesexport_wireframe.def file created above.
d. On the 'Data to Export' tab:
Export = Entire Part (This is a mandatory setting.)
Curves = ON
Surfaces = OFF
Solids = OFF
c. OK the Export to IGES Options dialog.
The IGES file created will have all edges of the model as curves.
