Reading your drawing
How Cizgen inspects, measures, and even sees your drawing so its answers and edits reflect what is really there.
Before Cizgen answers a question or draws anything, it reads your drawing. This is what makes its work grounded in reality instead of guesswork. You don't invoke any of this directly — Cizgen chooses what to read based on your request — but it helps to know what it can perceive.
Getting the big picture
Cizgen starts most tasks by taking an overview of the drawing: the units and extents, how many objects there are, the layers in use, sample text, and block names. This tells it what kind of drawing it's working with before it looks closer.
Looking at a specific area
You can point Cizgen at a part of the drawing and it will summarize that region — how many objects of each type and layer are there, and what text sits inside it. If a region is extremely dense, it says so rather than drowning in detail, and zooms in further.
To point at an area, attach a region to your message or ask Cizgen to have you select one. See Selecting objects and regions.
Reading text and object details
- Text — Cizgen can read the TEXT and MTEXT in the drawing (labels, notes, tags) along with where each sits.
- Object details — for specific objects it can read exact geometry and properties: polyline vertices, circle centers and radii, arcs, text, and each object's bounding box.
- Nearest objects — it can find what's closest to a given point and how far away it is.
Seeing the drawing
Cizgen can render a region to an image and look at it visually — independent of your current zoom or pan. This lets it reason about layout and appearance the way you would by looking, not just from raw coordinates.
Measuring
Cizgen can measure precisely:
- Distances, deltas, and angles between two points.
- Exact snap points on objects — endpoints, midpoints, centers, intersections, and more — so its measurements and drawings land exactly on existing geometry.
See Verifying results for how it checks measurements against what you asked for.
Recognizing rooms and symbols
Cizgen can detect higher-level structure without guessing:
- Spaces — enclosed rooms or areas, their size, and any name label inside them. This works whether a room is one closed polyline or separate walls forming a loop.
- Repeating symbols — it can group identical repeated symbols together, count them, and (once you label a group) recognize the same symbol elsewhere. See Symbol catalog.
Everything on this page is read-only — none of it changes your drawing. Cizgen can explore as much as it needs to; only writing requires your approval.
