You are refering to the icon. The icon is a name match to the operation name, and then falls back to a hard coded one for the operation type. The OOTB icons are separate files in the install, but you can add your own icons as bmp files. For example, it looks like you have a customized CAVITY_MILL operation called TROCHOIDAL. If you put an icon trochoidal.bmp in the UGII_BITMAP_PATH, it will be displayed instead of the built in CAVITY_MILL icon.
There are more options and details if you want to go deeper. You can override the name match by using an attribute, but the name match is simpler. You can also read about the search bath for user bitmaps in the help.
Check the syslog to see if UGII_BITMAP_PATH is defined. If it is not defined, then you should define it where you keep your customization. The search path for bitmaps is explained in the help
I do not recommend putting any user customization in the path of the install. I would do all of your customization someplace else - see this video on Getting Started with NX CAM Customization for how to use user files without touching your install.
The problem with making edits in the NX install tree is 2-fold
1) Your change may break NX (you can fix using your backups)
2) An NX update (MR, MP) may over-write your change (if you don't back up your changes as well, they could be lost)
There's also a side issue (less so if you have a backup somewhere else): figuring out what you changed in version "X", to apply the same changes when you go to version "Y"
If you go over to the NX customization & programming forum, "pinned" to the top is a thread on the "NXCustom utility" - I suggest you download the file appropriate to your version of NX and read the "readme". This offers a (more or less) standard way to add customizations in a SEPARATE area (separate than the install folder). Note this also works with network drives, to allow you to share the same customizations for all users.
Production: NX10.0.3.5 MP16/TC11.2
I'd rather be e-steamed than e-diseaseled
I still can't figure out how to change the icon though.
In your syslog, what is the value of UGII_BITMAP_PATH?
What is the name of the operation in the template part?
After getting a little free time to work on this I finally got around to creating the customization folder that you guys recommended and I was able to get everything finished with the customization.
Thanks a lot for your help and in being patient with me.
Here's what I have. Its a little ugly but I can change that later.
