Someone asked if it was possible to launch this from the MasterCAM toolbar.
The answer is yes. You'll need to create a new VBScript, with this..
Code:
Const THE_FILE = "C:\TapDrillCalculator.exe"
ShellAndWait THE_FILE, False
Then save it, and modify the toolbar via Screen/Config, and point to that
VB script. If you don't have 9.1, you can't do it.
'Rekd
p.s., replace the path with yours..
