Hands-on 2: use Codex connected to Rhino to generate an editable model.

Read PROJECT.md, especially the Exercise 2 teaching model brief. This task is model generation through the live connection. It does not use the ConvoAI 3D design-iteration skill yet.

Discover the actual Rhino tools and their documentation. Read the active Rhino document identity first. Work only in a new empty workshop document. If an unrelated or unsaved document is active, stop and ask me to open the correct one; do not clear it or switch away from it.

In that empty document, use metres and absolute tolerance 0.001 m. Create the seven specified objects on the exact full layer paths in PROJECT.md: the Platform, two guide curves, ServiceCore and three roofs. The five solids must be editable closed Breps. Build from the stated coordinates with documented supported operations. Do not substitute a ready-made model, a standalone rhino3dm file, meshes, image generation or a script that I have not executed in Rhino. Avoid booleans, extra objects and detail for this first model.

Explain the short build plan, then perform it through the live connection. Re-query the actual resulting objects, IDs, full layer paths, geometry types and bounding extents. Check them against the brief and report any mismatch. Capture an oblique arrival view and top view, recording their comparison cameras.

Save outputs/exercise-02/BASELINE.3dm without overwriting an existing file. Verify the saved file by reopening in native Rhino through the supported route. If the connection cannot reopen it, tell me the exact file to open manually, then re-read the actual reopened document before marking that step complete. Preserve unrelated open documents.

Save the brief, operation record, actual views and checks under outputs/exercise-02/. Show the model and state which checks actually passed. Stop after one diagnosed repair if the same issue recurs. If no live Rhino connection is available, report the blocker and stop; do not label a written script or library-only result as a completed connected exercise.
