Backplot & auto-generate

At a glance

  • Operations generate the moment you click OK—no Generate button to remember
  • A crisp backplot draws on the model: rapids, cutting moves, arcs, and leads each in their own color
  • Toolpaths draw on while they compute, with a live percentage on the operation and cancel any time
  • Edit the model and only the affected operations rebuild; adds, edits, and reorders undo and redo

Committed operations draw a crisp toolpath backplot right on the model — rapids, cutting moves, arcs, and lead-in/out each in their own color — with direction arrows you can toggle from the View HUD. It's how you see the cut before you cut it.

No Generate button to remember

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.

Watch it generate

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.

Tracked like everything else

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.
