3d sphere drawing lesson plan high

To create a 3D model in SketchUp, you lot're constantly switching amongst the drawing tools, views, components, and organizational tools. In this article, y'all find 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 see three ways to depict a 3D model of a chair. In the kickoff two examples, you see two methods for creating the same chair:

• Subtractive: Extrude a rectangle to the height of the chair. Then use the Push/Pull tool () to cut away the chair shape.
• Additive: Start by modeling the chair seat. Then extrude the back and the legs with the Push/Pull tool.

In the third example, you see 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: Yous can use the tips and techniques demonstrated in these chair examples to create all sorts of other complex 3D models.

Drawing a bowl, dome, or sphere

In this case, you wait at one way to draw a bowl and how to apply the technique for creating a bowl to a dome or sphere.

In a nutshell, to create bowl, you depict a circle on the ground plane and a profile of the bowl's shape directly above the circle. And so you use the Follow Me tool to turn the outline into a bowl by having it follow the original circumvolve on the ground plane.

Hither's how the process works, step-past-step:

1. With the Circle tool (), depict a circle on the footing aeroplane. These steps are easier if you beginning from the cartoon axes origin point. The size of this circle doesn't matter.
2. Hover the mouse cursor over the origin then that the cursor snaps to the origin and then move the cursor upwardly the blueish centrality.
3. Starting from the blue axis, draw a circle perpendicular to the circumvolve on the ground plane (that is, locked to the red or green centrality). To encourage the inference, orbit so that the greenish or red axis runs approximately left to correct forth the screen. If the Circle tool doesn't stay in the green or red inference direction, printing and agree the Shift key to lock the inference. The radius of this second circumvolve represents the outside radius of your bowl.
4. With the Offset tool (), create an kickoff of this second circle. The beginning altitude represents the bowl thickness. Check out the following figure to meet how your model looks at this point.
   
5. With the Line tool (), draw two lines: i that divides the outer circumvolve in half and one that divides the inner circumvolve that you created with the Offset tool.
6. With the Eraser tool (), erase the top half of the 2d circumvolve and the face that represents the inside of the bowl. When you lot're done, you accept a profile of the basin.
7. With the Select tool (), select the edge of the circle on the ground plane. This is the path the Follow Me tool will utilize to complete the bowl.
8. With the Follow Me tool (), click the profile of the bowl. Your basin is complete and yous can delete the circumvolve on the ground airplane. The following figure shows the bowl profile on the left and the bowl on the correct.

Note: Why practise you lot take to draw two lines to split the offset circles? When you lot describe a circle using the Circle tool (or a curve using the Arc tool, or a curved line using the Freehand tool), y'all are actually drawing a circle (or arc or curve) entity, which is fabricated of multiple-segments that human action similar a unmarried whole. To delete a portion of a circle, arc, or curve entity segment, you need to break the continuity. The start line you draw creates endpoints that break the segments in the outer circle, only not the inner circle. Cartoon the 2nd line across the inner circumvolve breaks the inner circumvolve into two continuous lines.

You tin can apply these aforementioned steps to create a dome by only cartoon your contour upside down. To create a sphere, you don't demand to change the second circle to create a profile at all. Check out the following video see how to create a sphere.

Creating a cone

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

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

1. With the Circle tool, draw a circle.
2. Use the Push/Pull tool to extrude the circle into a cylinder.
3. Select the Motility tool ().
4. Click a cardinal bespeak on the top edge of the cylinder, as shown on the left in the figure. A cardinal point is aligned with the red or green axis and acts as a resize handle. To find a cardinal point, hover the Move tool cursor around the edge of the acme cylinder; when the circle border highlighting disappears, this indicates a cardinal point.
5. Move the border to its center until it shrinks into the bespeak of a cone.
6. Click at the center to complete the cone, as shown on the left in the figure.

Here are the steps to model a cone by extruding a triangle along a circular path:

1. Depict a circle on the ground plane. You'll find it's easier to align your triangle with the circumvolve'southward heart if you start drawing the circumvolve from the axes origin.
2. With the Line tool (), draw a triangle that's perpendicular to the circle. (See the left image in the following figure.
3. With the Select tool (), select the face of the circle.
4. Select the Follow Me tool () and click the triangle face, which creates a cone almost instantaneously (equally long as your reckoner has the sufficient memory). You tin see the cone on the right in the following effigy.

Creating a pyramidal hipped roof

In SketchUp, you can easily depict a hipped roof, which is just a unproblematic pyramid. For this instance, y'all run into how to add the roof to a simple one-room house, too.

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

1. With the Rectangle tool (), draw a rectangle large plenty to cover your building. To create a truthful pyramid, create a square instead of a rectangle. The SketchUp inference engine tells y'all when you're rectangle is a square or a aureate section.
2. With the Line tool (), depict a diagonal line from one corner to its contrary corner.
3. Draw some other diagonal line from ane corner to another. In the effigy, you come across how the lines create an X. The example shows the faces in X-Ray view so you lot can come across how the rectangle covers the floor plan.
   
4. Select the Move tool () and hover over the middle point until a green inference point is displayed.
5. Click the center indicate.
6. Motion the cursor in the blue direction (upwardly) to pull up the roof or pyramid, as shown in the figure. If you need to lock the move in the blue direction, press the Up Arrow fundamental as you move the cursor.
7. When your roof or pyramid is at the desired height, click to finish the motility.

Tip: When you're creating a model of house or multistory edifice, organize the walls and roof or each floor of your building into dissever groups. That way, you can edit them separately, or hide your roof in order to peer into the interior floor plan. Run into Organizing a Model for details about groups.

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

Here are a few tips for finding a edifice's footprint:

• If you're modeling an existing edifice, trace the outline of the building with the cartoon tools. Unless the edifice is obscured past copse, you lot tin can find an aerial photograph on Google Maps and trace a snapshot. From within SketchUp, y'all can capture images from Google and load them directly into a model, as shown in the post-obit figure.
• If you lot don't have an aerial photo of the existing building y'all desire to model, yous may need to try the old fashioned route: measuring the exterior to create the footprint and drawing the footprint from scratch. If literally taking measurements of an entire edifice is impractical, yous tin employ tricks such equally using the measurement of a single brick to judge overall dimensions or taking a photo with an object or person whose length you lot exercise know. See Measuring Angles and Distances to Model Precisely for more details.

If you're able to commencement with a snapshot of your footprint, the post-obit steps guide yous through the process of tracing that footprint. First, prepare your view of the snapshot:

1. Select Camera > Standard Views > Top from the menu bar.
2. Select Camera > Zoom Extents to brand sure you tin see everything in your file.
3. Use the Pan and Zoom tools to frame a good view of pinnacle of the building that y'all want to model. You need to be able to come across the building clearly in order to trace its footprint. Come across Viewing a Model for details nigh using these tools.
4. Choose View > Face Style > X-Ray from the menu bar. In Ten-Ray view, y'all can see the pinnacle view of the building through the faces that y'all draw to create the footprint.

Afterward you lot set up your snapshot, endeavour the techniques in the following steps to trace the building footprint:

1. Set the drawing axes to a corner of your building. Run into Adjusting the Drawing Axes for details.
2. With the Rectangle tool (), draw a rectangle that defines office of your edifice. Click a corner and so click an opposite corner to depict the rectangle. If your edifice outline includes non–90-degree corners, curves or other shapes that you can't trace with the Rectangle tool, use whichever other drawing tools y'all need to trace your building'southward footprint.
3. Go on drawing rectangles (or lines and arcs) until the entire building footprint is divers by overlapping or adjacent rectangles, as shown on the left in the following figure. Make certain there aren't any gaps or holes; if at that place are, fill them in with more than rectangles.
4. With the Eraser tool (), delete all the edges in the interior of the building footprint. When yous're washed, you should have a unmarried face divers past a perimeter of straight edges. You may want to turn off X-Ray view, as shown on the correct in the following figure, in order to see your faces and concluding footprint conspicuously.
   
5. Some unproblematic buildings have a single exterior wall pinnacle, but most have more than i. After yous complete the footprint, use the Line tool to subdivide your building footprint into multiple faces, each corresponding to a different exterior wall height, as shown in the post-obit figure. And so, you can use the Push button/Pull tool () to extrude each area to the correct building superlative.

Creating a polyhedron

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

To illustrate how yous can create a circuitous shape with basic repeating elements, this example shows you how to create a polyhedron called a rhombicosidodecahedron, which is made from pentagons, squares, and triangles, equally shown in the effigy.

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

1. Institute the correct angle between the start square and the pentagon, and betwixt the kickoff triangle and the foursquare. Meet Measuring Angles and Distances to Model Precisely for details about measuring angles with the Protractor tool.
2. Mark the exact middle point of the pentagon, which is shown hither on a dark-green surface that has been temporarily added to the pentagon component. This is the axis around which the copies will exist aligned.
   
3. Make the square and triangle components, and so group the ii components. For details about components, encounter Developing Components and Dynamic Components. To learn about groups, see Organizing a Model.
4. Preselect the objects that yous want to copy and rotate (in this example, the group you just created).
5. Select the Rotate tool ().
6. Align the Rotate cursor with the pentagon face up and click the center point of the pentagon, as shown in the following figure.
   
7. Click the Rotate cursor at the point where the tips of the square, triangle, and pentagon come up together.
8. Printing the Ctrl key to toggle on the Rotate tool'due south re-create function. The Rotate cursor changes to include a plus sign (+).
9. Movement the cursor to rotate the selection around the axis. If you originally clicked the bespeak where the tips of the foursquare, triangle, and pentagon came together, the new group snaps into its new position, as shown in the following effigy.
   
10. Click to finish the rotate functioning.
11. Continue rotating copies effectually the axis until the shape is complete. As you build the rhombicosidodecahedron, you demand to group unlike components together, and rotate copies of those groups effectually various component faces.

Tip: If the component you lot are rotating around is not on the crimson, dark-green, or blueish airplane, make sure the Rotate tool'southward cursor is aligned with the face of the component earlier you click the center point. When the cursor is aligned, press and hold the Shift key to lock that alignment as yous move the cursor to the center betoken.
