Use when the user asks whether their Simplio3D options point at the right parts, why a material or option changes nothing on the 3D model, what parts or meshes a Simplio3D model contains, or where a part sits in the scene.\n---\n\n# Check 3D targets in a Simplio3D project\n\nRead-only. Resolve the project by name first (workspace-navigation skill). The user's explicit instructions take priority over this guidance, within what this read-only version can do.\n\nSimplio3D targets 3D parts **by mesh name**. A name that isn't in the model file silently does nothing: the option saves, the page loads, and nothing changes on the model. That is what this check finds.\n\n## Steps\n\n1. `validate_project` with `deep: true`. It opens the project's model files (the first few) and cross-checks every part name options, rules and animations use. Look for `part-target-unknown`, `rule-part-unknown`, `rule-3d-object-unresolved`, `variant-target-model-missing`, `animation-part-unknown` and `texture-target-missing`.\n2. For each missing name, find what the model really contains:\n   - `list_model_parts` for a model's mesh names (flat list with paths),\n   - `find_scene_objects` to search parts by name,\n   - `get_scene_hierarchy` for the nested groups.\n3. Suggest the closest real name for each missing one, and say which option or rule uses it. Don't claim a match you haven't seen in the tool results.\n\n## Explain the scene\n\n- `get_scene_hierarchy`: the model's groups and parts, addressed by slash-separated paths.\n- `get_object_details`: one part's position, rotation, scale and bounds, and which options or rules reference it.\n- `get_object_spatial_context`: where a part sits relative to others (regions, neighbours, relative size), computed from the geometry. Use it instead of guessing positions.\n- `get_model_pivots`: each model's Edit Axis pivot. Number inputs that resize parts do not use it: a part grows around its own origin in the 3D file, so a part that grows the wrong way needs its origin moved in the 3D modelling tool.\n\n## Things to know\n\n- Material options and part visibility work on meshes. A name that is a **group** in the file matches nothing for them; conditional rules can hide whole groups.\n- Two meshes with the same name in different groups are both targeted by that name.\n- After a model is replaced with a new version, parts that were renamed or merged stop matching. `validate_project` flags them.\n- A material option that changes nothing on the model can also be pointing at a 3D object that is no longer in the scene (finding: variant-target-model-missing). Retargeting the option fixes it.\n\n## Fixing targets\n\nThis version doesn't change projects. Tell the user which option or rule to retarget and to which part; they pick the parts in the option's target list in the Simplio3D editor.\n"
