What SketchUp Free actually includes

SketchUp Free runs entirely in a web browser. No installation, no licence key, no annual fee. Here is what it gives you:

What it does not have — and the workarounds

Missing from FreeWorkaround
LayOut (dimensioned 2D drawings)Export PNG views and add dimensions in Canva, Illustrator, or Affinity Designer. Works fine for student portfolios.
Works offlineSave your work regularly to the cloud. Download a local .skp backup from File → Download. Open files locally if you have Pro.
Import DXF/DWG filesIf you need to bring in existing CAD drawings, export them as image files and trace in SketchUp, or use a conversion service first.
Advanced renderingSketchUp Free renders look clean and presentation-ready with good material choices. For photorealistic renders, export to Lumion or use free render services.
Extensions / pluginsMost critical plugins (Curviloft, Fredo6 tools) are for Pro only. For standard architectural work, the built-in tools are sufficient.

The 3D Warehouse — most tutorials ignore this

The 3D Warehouse is built into SketchUp Free and most tutorials treat it as a secondary feature. It should be the first thing you use after setting up your walls. Inside the Warehouse:

Furniture — sofas, beds, kitchen units, bathroom fittings, dining tables — all free, all to scale

Landscaping — trees, shrubs, grass surfaces, garden furniture

Vehicles — cars at correct scale for site plan context

People — figures that give your model a sense of scale

Building components — stairs, doors, windows with correct dimensions

Using Warehouse assets means your model looks finished and realistic without spending hours modelling individual pieces. A bathroom takes two minutes to furnish — download toilet, basin, shower tray, and you are done.

Shadow studies — a feature most students never use

SketchUp Free includes a solar shadow tool that simulates sun position at any time of day and date for any location on earth. For design projects where solar orientation matters — which is almost all of them — this is an incredibly useful tool that is completely free.

1
Go to Window → Model Info → Geo-location and set your project location — a town, city, or coordinates.
2
Open View → Shadows to turn shadows on.
3
Use the shadow toolbar (View → Toolbars → Shadows) to adjust time of day and time of year. Watch how shadows move across your building.

When to upgrade to Pro

The honest answer is: most students do not need to. The cases where Pro becomes genuinely useful are:

If none of those apply to your current project, stay on Free. Learn the tool properly on the free version first — the skills transfer directly to Pro if you upgrade later.
