Selecting objects and regions
Point Cizgen at exactly what you mean — pick objects when it asks, or mark an area to work in from the panel or with CIZGENREGION.
Often the fastest way to get a precise result is to show Cizgen what you mean instead of describing it. There are two ways to do that.
When Cizgen asks you to select
If a task needs specific objects or a location, Cizgen pauses and shows a highlighted, pulsing card — a clear sign the run is waiting on you, not stuck.
Start the selection
The card offers to select an object, multiple objects, or an area. Click the one you need. The panel shows "Selecting in AutoCAD…" and hands control to the drawing.
Pick in the drawing
Pick the object(s) in AutoCAD, or drag a box for an area, exactly as you normally would.
Confirm
The card shows what you picked (for example, 3 selected or Area selected). Click OK to send it, or Change to pick again.
Cizgen then continues the task with precisely the objects or area you chose.
Marking an area to work in
You can also point at an area before you say anything, so Cizgen knows where to look from the start. A marked area is outlined on the canvas and labelled with a letter — A, then B, and so on — and it appears as a chip above the prompt box.
There are two ways to mark one, and they produce the same region:
From the panel
Click the + button next to the prompt box, choose Select region, and rubber-band a box on the canvas.
Or from the AutoCAD command line
Type CIZGENREGION and drag a rectangle. This works even when the panel is closed — and it's
how you point at the drawing from an app connected through Cizgen MCP.
Then just talk about it
Say what you want in your own words: "count the radiators in the region I marked", or "dimension region B". Cizgen works inside those bounds.
A mark stays until you remove it, so one mark can scope a whole conversation instead of being re-drawn for every message. To remove one:
- Click a chip's × in the panel — removes that region.
- Run
CIZGENREGIONagain and choose Clear — removes every mark in the drawing (List prints them with their coordinates).
Clicking a chip zooms the drawing to that region.
Marks belong to the drawing they were made in, so a mark in one tab never leaks into work on another. If you have marked several areas, name the one you mean by its letter ("region B") — otherwise Cizgen will ask which one.
Cizgen sends a picture of a region the first time it goes out with a message; later messages carry only its bounds. You keep the scope without paying for the same image on every turn.
Which one should I use?
| Best for | Lifetime | |
|---|---|---|
| Cizgen asks you to select | Cizgen already knows it needs something specific | That one step |
Marking an area (+ or CIZGENREGION) | A working area you'll refer to repeatedly | Until you remove it |
Answering the assistant's questions
Sometimes Cizgen needs a decision rather than a selection. It will ask right in the chat:
- Pick an option — it offers buttons to choose from.
- Answer a question — it gives you a box to type a short answer.
These pauses, like selection and approval, are shown clearly so it's always obvious when the run is waiting on you.
