Place Shapes Toolbar Extension for SketchUp

A toolbar for placing basic shapes (primitives)


Place Shapes Toolbar IconThis extension adds a toolbar (and some menu items) that lets you easily place several common 3D shapes (geometric primitives). While SketchUp’s native toolset allows you to create any of these shapes without too much effort, using this toolbar permits quick “solids-based” modeling where you only work with added and subtracted primitives to end up with a perfectly watertight object that poses no problems for 3D printing, for example.

The toolbar is also a good starter shape set for beginners and kids that want to dabble in 3D modeling but have no interest (yet) in learning e.g. the intricacies of the follow-me tool. To be honest, I made this extension because our daughter wanted to “make a penguin” and I was too lazy to explain the follow-me tool…

Before placing shapes, you can pick a base unit: foot, inch, mm, cm, m.


The easiest way to work with this extension is to show the “Place Shapes” toolbar and click on the shape you want to place. Alternatively use the Draw menu’s items. Most shapes will orient themselves based on the underlying geometry. You can also place multiple shapes – just go to the select tool (or hit the space bar or the Esc key) when you are done.

Once a shape has been placed, use the move and scale tools to work with it. If a shape doesn’t behave as you like, right-click on it and select “Unglue”. As you can see when placing any of the shapes, they all stick to the underlying geometry. You can also always explode a shape (using the right-click menu) to work with its raw geometry.

When you select a base unit from the dialog, all following placements will have that unit. Already placed items don’t scale. This allows you to model small stuff (e.g. for 3D printing) or large stuff (e.g. buildings).

Some tips

  • Turn on the X-ray face style (via the View menu) to enable snapping to hidden points.
  • Make hidden lines visible (View > Hidden Lines) to allow for more precise snapping.
  • These shapes work well with SketchUp Pro’s Solid Tools (intersect, union, subtract,…). All shapes are “solids” and if you work with only the shapes and the Solid Tools, then you will end up with a “solid” – perfect for 3D printing.
  • Use the 3D Text tool in SketchUp to add text to any of the shapes.
