I do quite a bit of helical trajectory milling but since updating to creo2.0 M110 the helical milling is quite slow calculating the tool path. At the bottom of the curve cut menu there is a button that you can turn off that is for viewing toolpath updated for every modification. When you turn this button off it speeds the calculation up. This button is always on when you open trajectory curve.
The question that I have is there a way to turn this off when i open trajectory curve until I want to use it ? I looked through the config options, but there seems to be none for trajectory milling.
I also looked on Olaf Cortens site at the config options that are hidden. There is one that looks like it is for just what I am asking about but when typed into the config it doesn't allow me to add it(mfg_trajectory_preview).
