Clearance validation — MEP Tools
The clearance and layout rules the validator checks, and their severities.
The validator runs continuously as you edit (shortly after each change) and lists every issue it finds, so you can resolve problems before exporting. Issues are either errors (the layout is invalid) or warnings (review recommended).
Errors — fix these
Errors mean the layout is physically invalid:
| Rule | Fires when |
|---|---|
| Room boundary | Equipment extends outside the room boundary. |
| Collision | Two equipment footprints overlap, or a footprint overlaps a column. |
| Wall overlap | Floor- or wall-mounted equipment overlaps the wall body. |
Warnings — review these
Warnings flag reduced or violated clearances:
- Clearance zone violated between two items, or intersecting a column or a wall.
- Maintenance clearance violated between items, or intersecting a column or wall.
How issues are shown
Each issue names the equipment or face involved and highlights the offending geometry on the plan (for example the clearance band or the intruding footprint), so you can jump straight to it. Overlapping rules are de-duplicated, so the same problem is reported once.
Resolve all errors before exporting to CAD or BIM. Warnings won't block export, but each one represents a clearance or access rule worth confirming against your project requirements.
This validator runs on every layout, always. AutoFit is a separate, optional feature with its own Result tab and its own findings — running it (or not) has no effect on the validator above, and vice versa.
