Auto Cylinder Start Point

Question - Why Does Auto Cylinder start at the bottom level of cylinder?

Yes, I know I can flip the vector of the feature to get it to start at the top but, when programming parts with hundreds of (threaded) holes, this gets tedious. In my head it would make more sense to either default to start at top level, or at least have an option to toggle top or bottom level.

When using fly mode, this becomes very problematic when jumping holes, as the controller wants to round the path and head straight for the bottom of the hole. In many cases, the solution to this is to just turn Fly mode off... This is also problematic when thinking of efficiency and implementing time saving tactics.

Please discuss.

I think it depends which end of the cylinder you click closest to when first selecting it.

avoidance move should prevent fly from arcing into the hole.

Incorrect, just did a quick test. Same hole used as shown above. Note the Z values of Hit - 1

Clicked near Z+ end of CAD cylinder: Clicked near Z- end of CAD cylinder:

When I was running CMM last year for these programs I had to set avoidance to a ridiculous number to do that. I ended up using clearplanes instead.

Can you just disable fly mode on that feature, then turn it back on? Probably not ideal either. I don't use fly mode, just curious.

Is this a CAD with clip planes on? I have had issues with clip planes when clicking on the model and actually registering where I click. It sometimes acts like the model is still somewhat there. I would hold Shift so that it highlights the feature for me when I mouse over the surfaces of that cylinder, then click there and see if it changes

It is, used clip plane just to be able to see the hole better. I'll do a quick test without that on

As far as I'm aware fly mode is either ON or OFF, no in-between or toggling between features. The help file is pretty misleading on this function as well, as it says it only works with move points, but that is not my experience. It generally, seems to work between most moves, with the exception of a few combinations of features and the moves between them.

Turned Clip plane off, and I get the same hit values as shown above...

From this old documentation I posted here

https://nexus.hexagon.com/community/public/pc-dmis/f/pc-dmis-for-cmms/149859/fly-mode-radius/861755

It says scroll to the right location in the program as it will be automatically placed at the current location in the part program. Now as far is if that means it can be toggled on and off, I'm not 100% sure. This could have changed in future versions, but it sounds like it can be. Similar to how you can add different format commands throughout reporting
