To create a 3D model in SketchUp, you're constantly switching among the drawing tools, views, components, and organizational tools. In this article, you observe several examples that illustrate ways yous can use these tools together to model a specific shape or object.

The examples illustrate a few of the different applications for creating 3D models in SketchUp: woodworking, modeling parts or abstract objects, and creating buildings. The examples are loosely ordered from the simple to the complex.

Drawing a chair

In the following video, you lot come across three ways to depict a 3D model of a chair. In the start two examples, yous run across ii methods for creating the same chair:

Subtractive: Extrude a rectangle to the height of the chair. Then apply the Push/Pull tool () to cut abroad the chair shape.
Condiment: First by modeling the chair seat. And then extrude the back and the legs with the Push/Pull tool.

In the third example, you run across how to create a more detailed and complex model, using components to simplify modeling the chair legs and rungs on the back of the chair.

Tip: You tin use the tips and techniques demonstrated in these chair examples to create all sorts of other circuitous 3D models.

Drawing a bowl, dome, or sphere

In this example, yous look at 1 manner to depict a bowl and how to use the technique for creating a bowl to a dome or sphere.

In a nutshell, to create basin, you depict a circle on the ground plane and a profile of the basin's shape directly above the circle. Then you utilise the Follow Me tool to plough the outline into a bowl by having it follow the original circumvolve on the basis aeroplane.

Here's how the process works, step-by-footstep:

With the Circumvolve tool (), draw a circle on the ground aeroplane. These steps are easier if you start from the drawing axes origin bespeak. The size of this circle doesn't affair.
Hover the mouse cursor over the origin so that the cursor snaps to the origin and then movement the cursor upwardly the blue centrality.
Starting from the blue axis, draw a circumvolve perpendicular to the circumvolve on the ground plane (that is, locked to the carmine or green axis). To encourage the inference, orbit so that the green or ruby centrality runs approximately left to right along the screen. If the Circle tool doesn't stay in the green or red inference management, press and agree the Shift key to lock the inference. The radius of this 2nd circle represents the exterior radius of your basin.
With the Kickoff tool (), create an offset of this second circle. The starting time distance represents the bowl thickness. Check out the post-obit effigy to see how your model looks at this indicate.
With the Line tool (), draw two lines: one that divides the outer circle in one-half and ane that divides the inner circle that you created with the Outset tool.
With the Eraser tool (), erase the acme half of the 2nd circle and the face that represents the within of the bowl. When you're done, you have a profile of the bowl.
With the Select tool (), select the edge of the circumvolve on the ground plane. This is the path the Follow Me tool will use to complete the basin.
With the Follow Me tool (), click the profile of the bowl. Your bowl is complete and you can delete the circle on the footing plane. The post-obit figure shows the bowl profile on the left and the basin on the right.

Note: Why exercise you have to describe two lines to divide the offset circles? When you describe a circle using the Circumvolve tool (or a curve using the Arc tool, or a curved line using the Freehand tool), you are actually drawing a circle (or arc or bend) entity, which is fabricated of multiple-segments that human activity like a single whole. To delete a portion of a circle, arc, or bend entity segment, y'all need to suspension the continuity. The outset line you draw creates endpoints that break the segments in the outer circle, but non the inner circle. Drawing the second line across the inner circumvolve breaks the inner circumvolve into two continuous lines.

Y'all tin use these same steps to create a dome by simply cartoon your profile upside downward. To create a sphere, you don't need to modify the second circumvolve to create a profile at all. Check out the following video run across how to create a sphere.

Creating a cone

In SketchUp, you can create a cone past resizing a cylinder face or by extruding a triangle forth a circular path with the Follow Me tool.

To create a cone from a cylinder, follow these steps:

With the Circle tool, draw a circle.
Use the Push button/Pull tool to extrude the circle into a cylinder.
Select the Move tool ().
Click a primal point on the top edge of the cylinder, every bit shown on the left in the figure. A cardinal point is aligned with the reddish or greenish axis and acts as a resize handle. To find a cardinal bespeak, hover the Move tool cursor effectually the edge of the top cylinder; when the circle edge highlighting disappears, this indicates a cardinal bespeak.
Move the border to its center until it shrinks into the betoken of a cone.
Click at the center to complete the cone, equally shown on the left in the effigy.

Hither are the steps to model a cone by extruding a triangle along a round path:

Describe a circumvolve on the ground aeroplane. Yous'll notice it's easier to marshal your triangle with the circumvolve'southward heart if yous start cartoon the circle from the axes origin.
With the Line tool (), depict a triangle that'due south perpendicular to the circle. (Meet the left image in the following figure.
With the Select tool (), select the face of the circle.
Select the Follow Me tool () and click the triangle confront, which creates a cone almost instantaneously (as long every bit your computer has the sufficient memory). You lot can come across the cone on the right in the following figure.

Creating a pyramidal hipped roof

In SketchUp, you lot can easily depict a hipped roof, which is but a unproblematic pyramid. For this example, you lot see how to add together the roof to a unproblematic one-room house, too.

To draw a pyramid (pull up a pyramidal hipped roof):

With the Rectangle tool (), draw a rectangle big enough to cover your building. To create a true pyramid, create a foursquare instead of a rectangle. The SketchUp inference engine tells you when you're rectangle is a square or a golden department.
With the Line tool (), draw a diagonal line from ane corner to its reverse corner.
Depict some other diagonal line from one corner to some other. In the figure, you run across how the lines create an X. The instance shows the faces in X-Ray view and then you can see how the rectangle covers the floor plan.
Select the Move tool () and hover over the center point until a dark-green inference signal is displayed.
Click the center signal.
Move the cursor in the blue management (up) to pull up the roof or pyramid, equally shown in the figure. If y'all need to lock the move in the bluish direction, press the Upwardly Arrow key equally you move the cursor.
When your roof or pyramid is at the desired meridian, click to finish the move.

Tip: When y'all're creating a model of house or multistory building, organize the walls and roof or each floor of your building into dissever groups. That manner, you lot tin can edit them separately, or hide your roof in order to peer into the interior floor programme. Encounter Organizing a Model for details about groups.

In SketchUp, the easiest way to start a 3D building model is with its footprint. After you have a footprint, you can subdivide the footprint and extrude each section to the correct height.

Hither are a few tips for finding a building's footprint:

If you're modeling an existing building, trace the outline of the building with the drawing tools. Unless the building is obscured by trees, you can find an aerial photo on Google Maps and trace a snapshot. From inside SketchUp, yous tin capture images from Google and load them directly into a model, as shown in the following figure.
If you don't have an aeriform photo of the existing building you desire to model, yous may need to try the old fashioned route: measuring the outside to create the footprint and drawing the footprint from scratch. If literally taking measurements of an entire building is impractical, you can utilise tricks such every bit using the measurement of a single brick to estimate overall dimensions or taking a photo with an object or person whose length y'all practise know. Meet Measuring Angles and Distances to Model Precisely for more details.

If you're able to start with a snapshot of your footprint, the following steps guide you through the process of tracing that footprint. Commencement, ready your view of the snapshot:

Select Camera > Standard Views > Pinnacle from the menu bar.
Select Photographic camera > Zoom Extents to make sure you tin encounter everything in your file.
Use the Pan and Zoom tools to frame a good view of top of the edifice that you want to model. You lot need to be able to meet the edifice conspicuously in order to trace its footprint. Encounter Viewing a Model for details almost using these tools.
Choose View > Face up Style > X-Ray from the carte bar. In X-Ray view, you can meet the height view of the building through the faces that y'all describe to create the footprint.

Afterward you prepare your snapshot, try the techniques in the following steps to trace the building footprint:

Ready the drawing axes to a corner of your building. Meet Adjusting the Drawing Axes for details.
With the Rectangle tool (), draw a rectangle that defines function of your edifice. Click a corner and and then click an opposite corner to describe the rectangle. If your building outline includes non–90-caste corners, curves or other shapes that you can't trace with the Rectangle tool, use whichever other drawing tools yous demand to trace your building's footprint.
Continue drawing rectangles (or lines and arcs) until the entire building footprint is divers past overlapping or adjacent rectangles, as shown on the left in the following figure. Make certain there aren't any gaps or holes; if there are, fill them in with more rectangles.
With the Eraser tool (), delete all the edges in the interior of the building footprint. When you're done, you should take a single face defined by a perimeter of directly edges. You may want to plow off X-Ray view, equally shown on the right in the following figure, in order to encounter your faces and terminal footprint clearly.
Some unproblematic buildings accept a unmarried exterior wall height, but most have more one. Subsequently yous complete the footprint, use the Line tool to subdivide your building footprint into multiple faces, each corresponding to a different exterior wall meridian, as shown in the following figure. Then, you can utilize the Button/Pull tool () to extrude each area to the correct building acme.

Creating a polyhedron

In this example, you lot see how to create a polyhedron, which repeats faces aligned around an axis.

To illustrate how you lot can create a complex shape with basic repeating elements, this example shows y'all how to create a polyhedron called a rhombicosidodecahedron, which is made from pentagons, squares, and triangles, as shown in the figure.

A rhombicosidodecahedron

The following steps explain how to create this shape by repeating faces around an axis:

Establish the right angle between the first square and the pentagon, and between the showtime triangle and the square. See Measuring Angles and Distances to Model Precisely for details nearly measuring angles with the Protractor tool.
Mark the exact middle point of the pentagon, which is shown here on a green surface that has been temporarily added to the pentagon component. This is the axis around which the copies will be aligned.
Brand the square and triangle components, and then grouping the two components. For details about components, meet Developing Components and Dynamic Components. To learn about groups, see Organizing a Model.
Preselect the objects that you lot want to copy and rotate (in this case, the group you only created).
Select the Rotate tool ().
Align the Rotate cursor with the pentagon face and click the center point of the pentagon, as shown in the following figure.
Click the Rotate cursor at the point where the tips of the square, triangle, and pentagon come together.
Printing the Ctrl fundamental to toggle on the Rotate tool's copy office. The Rotate cursor changes to include a plus sign (+).
Motion the cursor to rotate the selection around the axis. If you originally clicked the betoken where the tips of the foursquare, triangle, and pentagon came together, the new grouping snaps into its new position, equally shown in the post-obit figure.
Click to finish the rotate operation.
Continue rotating copies around the centrality until the shape is complete. As y'all build the rhombicosidodecahedron, y'all need to grouping different components together, and rotate copies of those groups around various component faces.

Tip: If the component you are rotating around is not on the red, green, or bluish plane, make sure the Rotate tool'southward cursor is aligned with the face of the component before you click the center point. When the cursor is aligned, press and hold the Shift key to lock that alignment every bit yous move the cursor to the eye betoken.
