SketchUp Layout: How to Produce Professional Construction Drawings From Your 3D Model

SketchUp Layout is the documentation side of SketchUp Pro. It takes your 3D model and produces scaled 2D drawings - plans, sections, elevations, and details - on proper drawing sheets with dimensions, annotations, and title blocks.

Most architects know SketchUp for modelling but underuse Layout for documentation. The result: they export images and paste them into other software, losing the live connection to the model. Layout does this properly - viewports stay linked, so when the model changes, the drawings update.

Here’s how to set up a professional drawing workflow from scratch.

The SketchUp-to-Layout Workflow (Overview)

The process works in two stages, and getting the SketchUp stage right is essential:

Stage	Where	What You Do
1. Scene setup	SketchUp	Create named scenes for each drawing view (plan, elevation, section, detail)
2. Drawing production	Layout	Place scenes as scaled viewports, add dimensions, annotations, and title blocks

Critical point: Layout doesn’t create views - it displays them. If your SketchUp file doesn’t have properly set up scenes, Layout has nothing to work with. Spend 80% of your setup time in SketchUp.

Stage 1: Setting Up Scenes in SketchUp

Each drawing sheet needs scenes prepared in SketchUp. Here’s what to set up for a basic drawing set:

Floor Plans

1. Create a Section Plane at 1200mm above the floor level (standard plan cut height)
2. Set the camera to Parallel Projection (Camera > Parallel Projection)
3. Set the view to Top (Camera > Standard Views > Top)
4. Turn on the section cut, turn off the section plane visibility
5. Set visible layers/tags: walls, doors, windows, furniture (if needed), dimensions
6. Save as a scene (View > Animation > Add Scene): name it “Plan - Ground Floor”

Elevations

1. Set camera to Parallel Projection
2. Choose the standard view matching the elevation (Front, Back, Left, Right)
3. Turn off interior elements, show only the exterior envelope
4. Enable shadows for depth (optional - set time for the best shadow angle)
5. Save as scenes: “Elevation - North”, “Elevation - East”, etc.

Sections

1. Create a Section Plane through the building where you want the cut
2. Right-click the section plane > Create Group from Slice if you want a cut-fill effect
3. Set camera to Parallel Projection, align perpendicular to the section
4. Save as scene: “Section A-A”

Details

1. Zoom into the area of detail
2. Use a style with thicker profile edges for clarity
3. Save as scene with a descriptive name: “Detail - Eave Connection”

Scene Settings That Matter

When saving scenes, SketchUp remembers these properties (check the Scene Manager):

Property	Keep Saved?	Why
Camera Location	Yes	The exact view position and zoom
Visible Tags	Yes	Controls what appears in each drawing
Active Section Planes	Yes	Different sections for different views
Style	Yes	Different line weights for plans vs details
Shadow Settings	Your choice	Elevations might show shadows, plans usually don’t
Axes	Usually no	Rarely needed per-scene

Stage 2: Working in Layout

Starting a New Layout Document

File > Send to Layout from SketchUp opens your model in a new Layout document. Alternatively, open Layout directly and insert a SketchUp reference (File > Insert).

Choose a template or start with a blank page. Set your paper size:

Drawing Type	Typical Paper Size	Scale
Floor plans (residential)	A3 or A2	1:50 or 1:100
Floor plans (commercial)	A1 or A0	1:100 or 1:200
Elevations	A3 or A2	1:50 or 1:100
Sections	A3	1:50
Details	A3	1:5, 1:10, or 1:20
Site plan	A1	1:200 or 1:500

Placing Viewports

1. Draw a rectangle on the page where you want the drawing view
2. Double-click it to enter the viewport, then right-click > Scenes and select your SketchUp scene
3. Set the Scale in the SketchUp Model panel (e.g., 1:100)
4. Lock the viewport by right-clicking > Lock to prevent accidental panning or zooming

Important: Always lock viewports after positioning them. Accidentally scrolling inside a viewport changes the view and breaks the scale.

Setting Viewport Rendering Mode

Each viewport can display differently:

Render Mode	Use For	Performance
Raster	Quick drafting, working views	Fast
Vector	Clean line drawings, plans, sections	Slower but crisp at any zoom
Hybrid	Vector lines over raster fills and textures	Best for final output

For construction drawings, use Hybrid or Vector. Raster looks pixelated when zoomed in or printed at high quality.

Dimensioning and Annotations

Adding Dimensions

Layout’s dimension tools work directly on viewport geometry:

1. Select the Linear Dimension tool (or Angular, Radial)
2. Click on one endpoint in the viewport, then the other, then place the dimension line
3. Layout reads the actual model dimensions at the correct scale

Dimension settings to adjust:

• Font size: 2-2.5mm at printed size (check in Document Setup > Fonts)
• Arrow style: architectural tick marks or small arrows (match your office standard)
• Offset from geometry: consistent distance from the drawing edge
• Stacking: dimensions should read from outside in, largest dimension outermost

Labels and Text

Use the Label tool for callouts with leader lines. Use Text tool for general notes.

Text hierarchy for drawings:

Text Element	Typical Size (at print)	Style
Drawing title	5-6mm	Bold
Room names	3-3.5mm	Regular or bold
Dimensions	2-2.5mm	Regular
Notes	2-2.5mm	Regular
Title block info	2.5-3mm	Varies

Auto-Text

Layout supports auto-text fields that update automatically:

• <PageNumber> - current page number
• <PageCount> - total pages
• <DateModified> - last save date
• <FileName> - document name
• Custom auto-text for project name, client, drawn by, etc. (File > Document Setup > Auto-Text)

Set these up once in your template and they populate across all sheets.

Title Blocks

Creating a Title Block

A professional title block should include:

Field	Source
Project name	Auto-text (set per document)
Client name	Auto-text
Drawing title	Manual text per sheet
Drawing number	Manual or auto-text
Scale	Manual (must match viewport scale)
Date	Auto-text (<DateModified>)
Drawn by	Auto-text
Revision	Manual text
Company logo	Inserted image
Page X of Y	Auto-text (<PageNumber> of <PageCount>)

Title Block as a Scrapbook

Create your title block once, save it as a Scrapbook entry. Then you can drag it onto any new sheet without recreating it.

Scrapbook location: Layout menu > File > Document Setup > References > Scrapbooks. Add your custom scrapbook folder.

Organising a Drawing Set

Typical Sheet Organisation

Sheet	Content	Scale
A-001	Cover sheet, location plan, drawing index	NTS / 1:500
A-100	Site plan	1:200
A-101	Ground floor plan	1:100
A-102	First floor plan	1:100
A-201	North and south elevations	1:100
A-202	East and west elevations	1:100
A-301	Section A-A and Section B-B	1:50
A-401	Wall section details	1:10
A-501	Door and window schedule	NTS

Layer Management in Layout

Use Layout layers (separate from SketchUp tags) to organise drawing elements:

Layout Layer	Content
Viewports	All SketchUp model viewports
Dimensions	All dimension lines
Annotations	Labels, notes, leaders
Title block	Title block and border
Graphics	North arrows, scale bars, symbols

Lock the title block layer to prevent accidental edits.

Updating Drawings When the Model Changes

This is Layout’s biggest advantage over exporting images: live link to the model.

When you modify the SketchUp model and save it:

1. Open the Layout file
2. Layout detects the model has changed
3. Click Update Model Reference (or File > Document Setup > References > Update)
4. All viewports update to reflect the new geometry

Dimensions that reference model geometry update automatically. Manual annotations (text notes, leaders) stay in place - you may need to adjust these if the layout shifts significantly.

---

Export Settings for Professional Output

PDF Export

File > Export > PDF with these settings:

Setting	Recommended Value
Quality	High
Output resolution	300 DPI minimum
Layers	Include all visible layers
Page range	All pages (for a complete set)
File size	Optimise images if sharing digitally

DWG/DXF Export

Layout can export to DWG for consultants who need AutoCAD-compatible files. Note that complex styles and textures may not translate perfectly - vector-rendered viewports export more cleanly than raster ones.

Common Mistakes

1. Not setting up SketchUp scenes properly. If you skip scene setup and try to position views directly in Layout viewports, you’ll constantly fight with views shifting. Always create and name scenes in SketchUp first.

2. Forgetting to lock viewports. One accidental scroll wheel inside a viewport changes the view and breaks the scale. Lock every viewport immediately after positioning it.

3. Using Raster rendering for print. Raster viewports look fine on screen but print with visible pixels. Switch to Vector or Hybrid for anything going to print or PDF.

4. Inconsistent scales across sheets. Label the scale on every drawing and double-check that the viewport scale matches the label. A mislabelled scale on construction drawings is a serious error.

5. Not using templates. Create one Layout template with your title block, layer structure, dimension style, and text formatting. Reuse it for every project. This saves hours and ensures consistency.
