Sample Code

Sample UDO programs exist for VB, C#, C++, and Java at: %UGII_BASE_DIR%\UGOPEN\SampleNXOpenApplications\<programming language>\UDO

Each program creates a simple UDO demonstrating these callbacks: Display, Selection, Attention Point, Fit, Edit, Information.

Run via NX: File tab → Execute → NX Open.... The program opens a new part if none is open, then prompts for a screen position — the UDO displays as a triangle at that point with a name indicating which language created it. Running all four language samples in one part shows (left to right): VB .NET UDO, C# UDO, C++ UDO, Java UDO.

The sample UDO is selectable: Menu→Information→Object on it prints custom info from the myInfoCB function. Right-click → "Edit User Defined Object" invokes myEditCB, prompting for a new screen position and moving the UDO there.
