how to draw a 3d right side up circle

To create a 3D model in SketchUp, y'all're constantly switching among the drawing tools, views, components, and organizational tools. In this commodity, you observe several examples that illustrate ways you 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, y'all see three ways to draw a 3D model of a chair. In the first two examples, you see two methods for creating the same chair:

• Subtractive: Extrude a rectangle to the elevation of the chair. Then use the Push/Pull tool () to cut away the chair shape.
• Additive: Outset by modeling the chair seat. So extrude the dorsum 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 employ the tips and techniques demonstrated in these chair examples to create all sorts of other complex 3D models.

Cartoon a bowl, dome, or sphere

In this example, yous look at i 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 basin, you depict a circle on the footing aeroplane and a profile of the bowl's shape directly in a higher place the circle. Then y'all utilize the Follow Me tool to plough the outline into a bowl past having it follow the original circle on the ground plane.

Here'southward how the procedure works, step-past-step:

1. With the Circle tool (), describe a circle on the footing plane. These steps are easier if you first 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 up the blue axis.
3. Starting from the blue axis, draw a circle perpendicular to the circumvolve on the basis plane (that is, locked to the blood-red or light-green axis). To encourage the inference, orbit so that the green or red axis runs approximately left to correct along the screen. If the Circle tool doesn't stay in the dark-green or ruby-red inference direction, printing and hold the Shift central to lock the inference. The radius of this second circle represents the outside radius of your bowl.
4. With the Kickoff tool (), create an get-go of this second circumvolve. The offset altitude represents the bowl thickness. Check out the following figure to see how your model looks at this indicate.
   
5. With the Line tool (), depict two lines: one that divides the outer circle in half and one that divides the inner circle that y'all created with the Offset tool.
6. With the Eraser tool (), erase the elevation half of the second circle and the face that represents the within of the bowl. When you lot're washed, you take a contour of the basin.
7. With the Select tool (), select the border of the circle on the ground plane. This is the path the Follow Me tool will utilize to complete the basin.
8. With the Follow Me tool (), click the profile of the bowl. Your bowl is complete and you can delete the circumvolve on the ground plane. The post-obit effigy shows the bowl profile on the left and the bowl on the right.

Annotation: Why practise you have to depict two lines to carve up the offset circles? When you draw a circumvolve using the Circumvolve tool (or a bend using the Arc tool, or a curved line using the Freehand tool), you are actually drawing a circumvolve (or arc or curve) entity, which is made of multiple-segments that deed like a unmarried whole. To delete a portion of a circle, arc, or curve entity segment, you need to break the continuity. The starting time line you draw creates endpoints that intermission the segments in the outer circumvolve, merely not the inner circle. Drawing the 2nd line across the inner circle breaks the inner circumvolve into two continuous lines.

You can use these same steps to create a dome by simply drawing your contour upside down. To create a sphere, you don't need to modify the 2d circle to create a profile at all. Check out the following video come across how to create a sphere.

Creating a cone

In SketchUp, you tin create a cone by resizing a cylinder face or by 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. Utilise the Push/Pull tool to extrude the circle into a cylinder.
3. Select the Motility tool ().
4. Click a cardinal point on the top edge of the cylinder, as shown on the left in the figure. A key bespeak is aligned with the red or green axis and acts as a resize handle. To observe a fundamental point, hover the Move tool cursor around the edge of the peak cylinder; when the circle border highlighting disappears, this indicates a cardinal point.
5. Movement the edge to its middle until information technology shrinks into the point of a cone.
6. 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:

1. Draw a circumvolve on the basis aeroplane. You'll find it's easier to align your triangle with the circumvolve's center if you commencement drawing the circle from the axes origin.
2. With the Line tool (), draw a triangle that's perpendicular to the circumvolve. (Meet 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 nearly instantaneously (every bit long as your computer has the sufficient memory). Yous can run into the cone on the right in the following figure.

Creating a pyramidal hipped roof

In SketchUp, you lot tin easily draw a hipped roof, which is just a unproblematic pyramid. For this example, yous see how to add the roof to a unproblematic 1-room firm, as well.

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

1. With the Rectangle tool (), depict a rectangle big enough to comprehend your edifice. 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 gilded section.
2. With the Line tool (), draw a diagonal line from one corner to its opposite corner.
3. Draw some other diagonal line from one corner to some other. In the figure, you come across how the lines create an 10. The example shows the faces in Ten-Ray view so you lot tin can see how the rectangle covers the floor plan.
   
4. Select the Move tool () and hover over the eye bespeak until a green inference point is displayed.
5. Click the center point.
6. Move the cursor in the blue direction (up) to pull up the roof or pyramid, as shown in the figure. If you need to lock the move in the blueish direction, press the Up Arrow primal every bit you motility the cursor.
7. When your roof or pyramid is at the desired height, click to finish the move.

Tip: When you're creating a model of house or multistory building, organize the walls and roof or each floor of your building into carve up groups. That mode, you tin can edit them separately, or hide your roof in social club to peer into the interior floor plan. See Organizing a Model for details virtually groups.

In SketchUp, the easiest fashion to commencement a 3D edifice model is with its footprint. Afterward yous take a footprint, you lot can subdivide the footprint and extrude each section to the correct tiptop.

Here are a few tips for finding a building'southward footprint:

• If y'all're modeling an existing building, trace the outline of the building with the drawing tools. Unless the building is obscured by trees, you lot tin can notice an aerial photograph on Google Maps and trace a snapshot. From inside SketchUp, you can capture images from Google and load them directly into a model, every bit shown in the following effigy.
• If you don't have an aerial photo of the existing building you want to model, y'all may need to endeavor the old fashioned route: measuring the exterior to create the footprint and drawing the footprint from scratch. If literally taking measurements of an entire building is impractical, y'all can utilize tricks such every bit using the measurement of a unmarried brick to estimate overall dimensions or taking a photo with an object or person whose length you do know. Run into Measuring Angles and Distances to Model Precisely for more details.

If y'all're able to showtime with a snapshot of your footprint, the post-obit steps guide you through the process of tracing that footprint. Kickoff, set upwards your view of the snapshot:

1. Select Camera > Standard Views > Height from the menu bar.
2. Select Camera > Zoom Extents to make sure y'all can see everything in your file.
3. Employ the Pan and Zoom tools to frame a good view of top of the building that you want to model. You lot need to be able to see the building clearly in guild to trace its footprint. Meet Viewing a Model for details nearly using these tools.
4. Choose View > Confront Mode > X-Ray from the menu bar. In X-Ray view, you can come across the top view of the building through the faces that you draw to create the footprint.

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

1. Ready the drawing axes to a corner of your building. See Adjusting the Drawing Axes for details.
2. With the Rectangle tool (), draw a rectangle that defines part of your building. Click a corner and then click an opposite corner to draw the rectangle. If your edifice outline includes non–90-degree corners, curves or other shapes that yous can't trace with the Rectangle tool, use whichever other drawing tools you need to trace your building'due south footprint.
3. Continue drawing rectangles (or lines and arcs) until the entire building footprint is divers by overlapping or next rectangles, as shown on the left in the following figure. Brand sure there aren't any gaps or holes; if there are, make full them in with more rectangles.
4. With the Eraser tool (), delete all the edges in the interior of the building footprint. When you're done, you should have a single face defined by a perimeter of straight edges. You lot may want to turn off X-Ray view, equally shown on the right in the following figure, in society to meet your faces and final footprint clearly.
   
5. Some simple buildings have a single outside wall height, but nearly have more than i. Subsequently 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 following figure. Then, you can use the Push/Pull tool () to extrude each area to the correct building height.

Creating a polyhedron

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

To illustrate how you can create a complex shape with basic repeating elements, this example shows you how to create a polyhedron chosen a rhombicosidodecahedron, which is made from pentagons, squares, and triangles, every bit shown in the figure.

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

1. Establish the correct angle between the starting time square and the pentagon, and betwixt the beginning triangle and the square. Run into Measuring Angles and Distances to Model Precisely for details well-nigh measuring angles with the Protractor tool.
2. Mark the exact center indicate of the pentagon, which is shown here on a green surface that has been temporarily added to the pentagon component. This is the axis effectually which the copies will be aligned.
   
3. Make the foursquare and triangle components, and then grouping the two components. For details near components, see Developing Components and Dynamic Components. To acquire about groups, see Organizing a Model.
4. Preselect the objects that you lot want to re-create and rotate (in this example, the group you just created).
5. Select the Rotate tool ().
6. Marshal the Rotate cursor with the pentagon face and click the centre point of the pentagon, as shown in the post-obit figure.
   
7. Click the Rotate cursor at the betoken where the tips of the square, triangle, and pentagon come together.
8. Press the Ctrl central to toggle on the Rotate tool's re-create function. The Rotate cursor changes to include a plus sign (+).
9. Move the cursor to rotate the selection around the axis. If yous originally clicked the point where the tips of the square, triangle, and pentagon came together, the new group snaps into its new position, every bit shown in the following figure.
   
10. Click to finish the rotate performance.
11. Continue rotating copies around the centrality until the shape is complete. As yous build the rhombicosidodecahedron, you need to group different 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 ruddy, light-green, or blueish plane, make sure the Rotate tool'due south cursor is aligned with the face of the component before yous click the heart point. When the cursor is aligned, press and hold the Shift key to lock that alignment as y'all motion the cursor to the centre point.
