Backplot & auto-generate

Operations generate the moment you click OK, and rebuild when you edit and re-commit. There's no separate Generate step to forget. Edit the model and affected operations flag themselves dirty — rebuild one with right-click → Generate, or Generate all dirty in one go.

Editing an operation rebuilds its toolpaths only when you changed something that can move the cutter — depths, stepdowns, tool diameter, picked geometry, entry and clearing settings.

Feeds, speeds, coolant and tool number apply instantly instead. The path is identical either way; only the numbers written onto it change, so there's nothing to recompute. That matters most on a dynamic clear, where a rebuild is the most expensive thing the workspace does — nudging a feedrate no longer costs you one. Opening an operation and closing it without changing anything is free too, whether you press OK or Cancel.

Right-click → Generate always does the full rebuild, clean or not, whatever you last changed. It's the manual override, and it never second-guesses you.

While an operation generates, its row in the tree shows a live percentage, and queued operations say they're waiting their turn. Long dynamic clears draw onto the model as they compute, chunk by chunk, so you watch the pocket fill in instead of staring at a frozen screen. Click a generating operation's spinner to cancel just that one — the rest of the queue keeps going — or cancel the whole batch from the Operations row. Right-click a finished operation for an Info readout: when it generated, how long it took, and how many moves it produced.

Click an operation in the tree and the viewport shows only its toolpaths — every other operation's backplot steps aside, even if the one you picked has its eye off. Your eye settings aren't touched: click any open space in the browser, any other row, or press Escape and everything returns exactly as you had it. Shift/Cmd-select several operations to focus that group. The focus carries through the whole workspace: press Play and the simulation runs just your selection, and the Post button writes just those operations to their own file.

Your settings stick — each dialog remembers your last tool, feeds and speeds, heights, and leads — so the next operation starts where the last left off. And adding, editing, reordering, or deleting a setup or operation marks the file unsaved, schedules autosave, and can be undone and redone, so CAM work is as safe as your model edits. A T-number badge on every row reads like the tool list your program will use, and the Operations row has its own eye to hide every toolpath in one click. Posting is covered in Machine posts.
