The approval gate

How Cizgen holds every change as a preview and applies it only after you approve, so nothing is edited without your say-so.

Cizgen never changes your drawing on its own. Everything it draws, edits, or deletes is first staged as a preview, and it becomes permanent only when you approve it. This is the most important thing to understand about working with Cizgen.

How a change is applied

It draws to a preview. New geometry, edits, and deletions are staged on a temporary preview layer — visible on your canvas, but not yet part of the drawing.
It checks its own work. Before asking you, Cizgen renders the pending change and runs an automatic geometry check for problems like dangling ends, duplicates, overlaps, or self-intersections, and fixes what it can.
It asks you. A bar appears at the bottom of the panel: "Preview ready on the canvas," with a short summary of what will change (for example, 3 drawn · 2 blocks placed).
You decide. Approve to apply it, or reject to discard it.

Approving and rejecting

Approve — press Enter or click Approve. The change is applied to your drawing.
Reject — press Esc or click Reject. The preview is discarded and the conversation continues, so you can refine your request.

Warnings and errors

Cizgen's self-check may flag things:

Warnings never block you. They appear as an amber, pulsing cue ("…— commit anyway?"). You can approve as normal if the result looks right to you.
Hard geometry errors turn the bar red. The primary button becomes a deliberate "Approve anyway" and is not pre-focused, so you can't apply a flagged result by reflexively pressing Enter — it takes an explicit click.

The "Approve anyway" override is there for the cases where you know better than the automatic check. Use it intentionally.

Why the assistant can't approve itself

Approval is enforced securely. The permission to commit a change is issued only when you click Approve — the AI model cannot grant it to itself. If Cizgen ever tries to apply a change before you've approved, the request is refused. This is what makes it safe to let the assistant work on its own.

After a change is applied

Once you approve, the change is a normal part of your drawing.

To take back an applied change, use AutoCAD's own UNDO.
To take back something Cizgen staged but you haven't approved yet, just reject it — or ask Cizgen to undo the last step. See Undo and recovery.
