Save Time with SimLab DWG Exporter for SketchUp: Settings That Ensure Accurate DWG Output

Export DWG from SketchUp Easily with SimLab DWG Exporter: Step-by-Step Guide

Converting SketchUp models to DWG is a common need when collaborating with architects, engineers, or CAD-focused teams. SimLab DWG Exporter for SketchUp streamlines the process by preserving geometry, layers, materials, and scale. This step-by-step guide shows a reliable, repeatable workflow to produce clean DWG files ready for AutoCAD or other CAD applications.

What you need

• SketchUp (Make, Pro, or newer) with your model ready.
• SimLab DWG Exporter plugin installed and activated.
• Basic understanding of SketchUp layers (tags), groups/components, and scenes.

Step 1 — Prepare your SketchUp model

1. Clean up geometry: Remove stray edges, hidden geometry, and unused components/components. Use Extensions > CleanUp³ or SketchUp’s native tools if available.
2. Use proper grouping: Put geometry that should remain together into groups or components to avoid exploding on export.
3. Organize with tags (layers): Assign tags to objects by discipline (walls, furniture, annotation) so they map cleanly to DWG layers.
4. Set units & scale: Ensure the model uses the real-world units you need (Window > Model Info > Units). DWG output will respect these units.
5. Simplify complex textures: Replace heavy image textures with basic materials if you only need linework; complex textures can bloat file size.

Step 2 — Open the SimLab DWG Exporter

1. From SketchUp’s menu, go to Extensions (or Plugins) > SimLab DWG Exporter > Export DWG.
2. The exporter dialog will appear with options for geometry, layers, materials, and export settings.

Step 3 — Configure basic export settings

1. File path & name: Choose an appropriate destination and filename for the DWG.
2. DWG version: Select the target DWG version (e.g., AutoCAD 2010, 2013). Choose one compatible with your recipients.
3. Units: Confirm export units match your SketchUp model units (mm, cm, m, inches, feet).
4. Scale: Typically set to 1:1 for architectural models. Use an explicit scale if you need a scaled drawing.

Step 4 — Map SketchUp tags to DWG layers

1. In the exporter’s layer mapping section, review how SketchUp tags are assigned to DWG layers.
2. Rename or create layer names to match company/CAD standards (e.g., A-WALLS, A-FURN).
3. Use visibility toggles to exclude non-essential tags (e.g., construction lines, reference geometry).

Step 5 — Geometry and export options

1. Explode groups/components: Decide whether to keep groups as blocks in DWG (recommended) or explode them into raw geometry.
2. Merge coplanar faces/edges: Enable options to reduce redundant lines and produce cleaner polyline output.
3. Convert arcs and circles: Ensure arcs/circles are exported as true DWG arcs/circles rather than segmented polylines if precision matters.
4. Curves and splines: Check how splines are approximated and adjust tolerance for smoother results or fewer vertices.
