Model Workflow Tools

Generate 3D is the main one-click building command for a prepared 2D floor plan. It runs the full wall, join, opening, and model-generation pipeline after the plan has been scaled, mapped, cleaned, and checked.

For the complete DWG/DXF preparation sequence, follow the Import 2D to 3D tutorial before the first generation run.

• Verify a known CAD dimension and source units.
• Map required layers to LizArk roles.
• Preview duplicates, overlaps, and gaps.
• Run Preflight and review its report.
• Save settings, then click Generate 3D.

To Elevation is a separate conversion workflow for prepared plan geometry that needs level or elevation remapping. It is not the label of the normal one-click building command.

Use Generate 3D for the standard full-plan build. Use To Elevation only when the project specifically needs its elevation-oriented remapping workflow.

Floor detection now lives inside To Elevation rather than as a separate toolbar command. Detect Floors performs an explicit rescan of the selected plan or the active model and refreshes elevation-level markers.

Use it before applying the To Elevation conversion when copied or edited plans may contain stale level metadata.

Incremental Rebuild opens a dedicated wizard that lets you choose the rebuild scope, then regenerates the edited zone instead of requiring a full-model rebuild for every local correction.

Select the changed 2D area before starting. The tool includes a preflight step and reports the affected walls and openings when the rebuild completes.

Finish Brush lets you hover a valid wall or structural surface and click to apply plaster or paint. P cycles apply and remove modes, I switches between interior and exterior, and Ctrl plus click temporarily removes the finish under the cursor.

Plaster creates a measured finish shell that preserves door and window openings. Paint remains a separate zero-thickness material layer. Each layer stores its finish type, side, material, opacity, and other settings with the source model object, so it can be refreshed or removed later.

This is BIM-like behavior inside SketchUp because the finish carries editable intent and a relationship to the building object. It does not turn SketchUp into a full BIM authoring platform.

• Apply or remove interior and exterior plaster independently.
• Apply paint to the plaster shell when one exists, or to the source face when it does not.
• Connected finishable surfaces can be expanded from the picked face.
• Automatic refresh can rebuild stale plaster after source geometry changes when enabled in Settings.
• Removing paint restores the plaster material beneath it where applicable.
