How to Make a Cone Roof in SketchUp — 3 Steps

Modeling a cone roof in SketchUp is one of the most searched architectural tasks for beginners and intermediate users alike, and the good news is that the built-in Follow Me tool handles it in three precise steps with zero plugins required. Whether you are building a conical turret on a Victorian house, a thatched hut, a pagoda spire, or a simple circular gazebo roof, the workflow is identical: draw a circular path that matches your wall’s footprint, draw a closed triangular profile that defines the slope and height, then let Follow Me sweep that profile around the path to produce a perfect rotational solid. The result is a geometrically accurate cone whose smoothness you fully control before the operation runs. SketchUp’s Pie tool (also called the Arc from Center tool) is useful when you only need a partial cone — a curved ramp, a conical lid, or a sectional cutaway — because it lets you draw a wedge-shaped path instead of a full circle. Beyond simple cones, the same Follow Me principle produces pyramid roofs when you replace the circular path with a square or polygonal one: draw a 4-sided polygon, extrude a triangular profile from each midpoint, and Follow Me wraps it cleanly. Understanding these three geometry types — cone, partial cone, and pyramid — covers the vast majority of decorative roofline shapes you will encounter in residential SketchUp models. This tutorial expands the core three-step method with segment-count math, profile orientation rules, group-context pitfalls, and post-processing tricks for softening facets and applying materials, so you finish with a roof that renders correctly and exports cleanly to every major renderer.

Key Features of the Follow Me Cone Roof Workflow

• Segment count is the master quality dial. SketchUp draws circles with 24 sides by default, giving you a 24-faceted cone. Immediately after drawing the circle, type a number followed by s — for example 48s or 96s — and press Enter to change the segment count before you do anything else. You can also select the circle edge, open Entity Info (Window > Entity Info), and change the Segments field at any time before Follow Me runs. Once Follow Me has swept the profile, the facet count is baked in and cannot be changed without redoing the operation. The rule of thumb: 24 sides is fine for a distant or small roof, 48–64 sides suits a medium close-up, and 96+ sides is for hero shots or high-resolution renders. Every doubling of segments roughly doubles the face count of the final cone, so balance quality against model weight.
• The profile must be a closed face, not just edges. Follow Me sweeps a face — it needs a flat polygon with an actual surface, not a wire outline. Draw the triangle for the cone profile (base = radius of the circle, height = ridge height, hypotenuse = slope line), make sure all three lines connect perfectly at their endpoints so SketchUp fills the face automatically, and confirm you can see the grey face before clicking Follow Me. If the face does not appear, look for a tiny gap at a corner: use the Tape Measure tool to check, then redraw the problematic edge. A common mistake is drawing the vertical height line slightly off-axis — lock it to the blue (Z) axis by holding Shift while drawing, or type the height in the Measurements box.
• The circular path and the profile must share exactly one endpoint. The most reliable setup is to draw the base circle centered at the origin, then draw the profile triangle starting from a point on the circle’s perimeter, so the triangle’s base corner touches the circle edge. This shared point is the hinge Follow Me pivots around. If the profile floats in space disconnected from the path, Follow Me will run but produce a twisted, torn mesh. Zoom in close to verify the connection before you run the operation.
• Pre-selecting the path gives a one-click result. Instead of activating Follow Me first and then clicking-dragging along the path, use the Select tool to click the circle edge once (SketchUp selects all connected edges of a circle as a single curve), then press the Follow Me toolbar button or choose Tools > Follow Me, then click the profile face once. The cone appears instantly. This pre-select workflow is faster, more predictable, and avoids the common mistake of letting go of the mouse mid-drag on a complex path.
• Soft-and-smooth edges make the cone look round. After Follow Me finishes, the cone is technically a many-sided prism with visible crease edges between facets. Select the entire cone (triple-click to select all geometry), right-click, and choose Soften/Smooth Edges. In the dialog, drag the angle slider to about 30–45 degrees and tick “Smooth normals” — this hides the facet lines and makes the surface appear curved in both the SketchUp viewport and in exports to rendering engines. You can also reach this via Window > Soften Edges. The underlying geometry stays polygonal; only the edge display changes.
• Pyramid roofs use the same Follow Me logic with a polygon path. Draw a square or hexagonal path on the footprint of the building, draw a triangular profile from the midpoint of one edge (pointing inward and upward to the ridge), pre-select the entire polygon path, activate Follow Me, and click the profile. SketchUp sweeps the triangle around each corner of the polygon, creating a hip roof. For a four-sided pyramid the path has 4 sides; for a pagoda-style hexagonal roof use 6 sides. The Pie tool comes in for partial cones: draw a wedge arc (two radii + an arc) as your path and Follow Me sweeps only through that angular range, producing a quarter-cone, half-cone, or any fraction you need.

How to Model a Cone Roof in SketchUp — Step by Step

1. Set up your axes and units. Open a fresh file or navigate to the location where the roof will sit. Confirm your units in Window > Model Info > Units — millimeters for architectural metric, inches for imperial. Drawing at real scale from the start prevents scaling surprises later. If the roof sits on top of a wall cylinder, place your camera top-down (Camera > Standard Views > Top) so you can see the footprint clearly.
2. Draw the base circle (the Follow Me path). Activate the Circle tool (keyboard shortcut C). Click once to set the center — use the origin or snap to the center of your wall. Before clicking the radius endpoint, type the exact radius value and press Enter (for example 4000mm for a 4-meter-radius roof). Immediately after the circle appears, type the segment count followed by s (for example 48s) and press Enter. The circle updates with more sides. This is your Follow Me path.
3. Draw the profile triangle. Switch to a front or side view (Camera > Standard Views > Front). Activate the Line tool (keyboard shortcut L). Click on a point on the perimeter of the circle — SketchUp’s inference engine will snap to it; look for the “On Edge” tooltip. Draw a vertical line upward to the ridge height: type the height value (for example 3000mm) while holding the Shift key to lock to the blue axis, then press Enter. Draw a diagonal line from the ridge point back down to the center of the circle at ground level. Finally, close the triangle by drawing a horizontal line from the center back to the perimeter point where you started. Confirm SketchUp has filled the triangle with a grey face. If not, retrace one edge to prompt face generation.
4. Pre-select the circular path. Switch back to an isometric or perspective view. Activate the Select tool (keyboard shortcut Space). Click once on the circle edge — all circle segments highlight in blue as a single curve entity. This is your path selection.
5. Run Follow Me. With the circle still selected, activate Follow Me via Tools > Follow Me or the toolbar button. Move your cursor to the profile triangle face — the cursor changes to a small Follow Me icon — and click once. SketchUp sweeps the triangle profile around the full circle, generating the cone. The operation is immediate on simple profiles; large segment counts on both path and profile can take a few seconds.
6. Clean up the base face. After Follow Me runs, SketchUp leaves the original circular base face and the profile triangle face in the model. Select and delete them if you only need the cone shell (for a roof sitting on walls below). If you need a closed solid for 3D printing or solid operations, keep the base face and use Entity Info to confirm it reads as a solid component.
7. Soften the facets. Triple-click the cone to select all its geometry. Right-click and choose Soften/Smooth Edges. Drag the angle slider to 45 degrees and enable Smooth normals. The visible crease lines disappear, leaving a smooth-looking cone surface. Click outside to deselect and check the result.
8. Apply a material. Open the Materials panel (Window > Materials on desktop, or the paint bucket icon). Select a roof tile, thatch, or metal material. Activate the Paint Bucket tool (keyboard shortcut B) and click the cone surface. SketchUp applies the material to all faces. For a realistic tile layout on a cone, you may need UV mapping in a renderer, but flat material color works well for schematic models and presentations.
9. Make it a component. Triple-click to select all geometry, right-click, and choose Make Component. Give it a meaningful name like “Cone Roof R4000 H3000”. This protects the cone from accidental merging with adjacent geometry and allows you to reuse or mirror it across the model.

Pro Tips for Cone Roof Modeling in SketchUp

• Fix the “Follow Me does nothing” problem with group context. This is the single most common issue. If your wall cylinder or footprint lives inside a group or component, the circle you draw inside that group is invisible to a profile drawn outside — or vice versa. Follow Me only reads geometry in the same editing context (the same “level”). The fix: double-click into the group containing the circle, copy the circle edge (Edit > Copy), exit the group (press Escape), paste in place (Edit > Paste in Place), draw your profile at the top level next to the pasted circle, run Follow Me, then delete the pasted circle and move the finished cone back into the group if needed. Never try to run Follow Me with path and profile in different groups.
• Use the Measurements box for exact ridge height, not free-hand dragging. When drawing the vertical line of your profile triangle, always type the height value in the Measurements box rather than dragging to an approximate position. A height typed as 3000mm is exactly 3000 mm; a dragged line is rarely exact. This matters when the cone must align with ridge beams, dormer tops, or section cut planes. SketchUp’s inference locks (Shift for axis lock, on-screen inference dots) are your allies for keeping all profile lines truly vertical or truly horizontal.
• Avoid reversing faces before painting. After Follow Me, check the face orientation of the cone’s exterior. The white (front) face should face outward. If the exterior looks blue-grey, the faces are reversed. Select all cone faces, right-click one, and choose Reverse Faces — or use Orient Faces if the cone has a mix. Painting a reversed face applies the material to the back side, which many renderers (V-Ray, Enscape, Lumion) treat as invisible or translucent, causing a “disappearing roof” in renders. Fix orientation before touching materials.
• For pyramid roofs, draw the profile from the midpoint of one polygon edge, not from a corner. When using a square path for a four-sided hip roof, the profile triangle should start at the midpoint of one side (snap to the midpoint inference dot) and rise to a single apex point directly above the polygon center. If you start from a corner, Follow Me produces a star-shaped twisted result instead of clean hip facets. Use the Tape Measure or a guide line to locate the midpoint precisely if SketchUp’s inference doesn’t snap there automatically.
• Partial cones with the Pie tool — use “angle snap” for precise wedges. The Pie tool (found under the Arc tool dropdown in the toolbar) draws arcs by center, two radius lines, and an arc. To make a quarter-cone (90 degrees), activate the Pie tool, click the center, drag one radius, then type 90 degrees in the Measurements box to lock the wedge angle. Close the wedge face by drawing the two straight radius lines if Pie doesn’t auto-close, verify the face exists, and use it as a Follow Me path for partial cone sections — useful for vaulted ceilings, conical canopies, and architectural cutaway diagrams.
• Match segment count between linked cones and cylinders for clean junctions. If a cone roof sits directly on a circular wall, both should have the same segment count and the same center/radius, so their perimeter vertices align exactly. A 48-segment cone on a 24-segment cylinder will have mismatched edges at the seam, visible as a zigzag gap. Draw both from the same center point, type the same segment count for both circles before any other operation, and the perimeter edges will coincide perfectly.

System Requirements

• SketchUp version: Follow Me and the Pie tool are present in all current SketchUp editions — SketchUp Free (web browser), SketchUp Go, SketchUp Pro, and SketchUp Studio. The workflow described here works identically in SketchUp 2019 through SketchUp 2026. No plugins or extensions are required.
• Operating system: SketchUp desktop (Pro/Go/Studio) runs on Windows 10/11 (64-bit) and macOS 12 Monterey or later as of the 2025/2026 releases. SketchUp Free runs in any modern web browser (Chrome, Edge, Firefox, Safari) on Windows, macOS, ChromeOS, and iPadOS — no installation needed.
• Hardware: Follow Me on a typical cone profile (48-segment circle, triangular profile) is instantaneous on any modern machine. Very high segment counts (200+ segments on path and profile simultaneously) can take several seconds on older hardware. A dedicated GPU is not required for modeling, but improves viewport performance when the model grows large.
