Shape
Extrude, revolve, loft, sweep
From profiles, faces or polygons, with start offsets, two sides and symmetric spans; lofts and sweeps with twist and frame control.
Modeling
Fast like a sketch. Exact like a kernel.
Push a face and the solid follows. Constrain the sketch behind it, drive it from a parameter, roll the timeline back and change your mind — on the same model, without switching modes.
Direct modeling
The tools you already know.
Line, Rectangle, Circle, Polygon, Arc; Push/Pull, Move, Rotate, Scale, Offset, Follow Me — with SketchUp's own keys if you want them, and an inference engine that snaps to endpoints, midpoints, centres, guides and axes.
- Values where the gesture is. Lockable fields beside the pointer: type a size where you measure it.
- Face regions. A profile drawn inside a face is imprinted into the solid, ready to push.
- Booleans: union, subtract, intersect, trim, split and outer shell.
- Keymaps: SketchUp's keys exactly, a Fusion-style preset, or your own.
Parametric sketches
Constraints that say what they will not do.
A minimum-change Newton solver reports the degrees of freedom left and refuses an edit that would over-constrain the sketch, instead of quietly picking a solution.
- Coincident, parallel, perpendicular, tangent, equal, symmetric, concentric and fix — and driving dimensions.
- Named parameters with units, checked dimensionally, usable in any value.
- Sketch on a face, and the sketch follows the face. 3D sketches and work geometry too.
- Text in any installed font; DXF and SVG imported into sketch entities.
Solid features
The features a real part needs.
Finish
Fillet, chamfer, shell, draft
On chosen edges and tangent chains; shell and thicken; draft about a fixed plane or a face that stands in for one.
Repeat
Patterns and mirror
Rectangular, circular and path patterns and mirror across a plane — in 3D, with live grips.
Edit
Direct face editing
Move, offset, replace or delete a face on any body, including an imported STEP with no history.
Hold
Persistent names
Every face and edge is named from its history, so a fillet or a sketch stays on its edge when the model upstream changes.
Parts
A verified parts library
Gears, ISO threads, bolts, nuts, washers, springs, flanges and knurls — signed parametric plugins that regenerate without the plugin.
History
A timeline you can argue with.
- Roll back with the marker; new work goes in where it stands.
- Reorder with a drag that knows beforehand whether a step may pass the one it is built from.
- Configurations: variants of parameters, suppressions and values.
- Branches with a three-way merge that will not commit a document that does not build.
- Replay the build step by step, and record it as WebM or GIF.
Analysis
Measure before you make.
- Mass properties from each material's density, with inertia about the centre and the origin.
- Interference between bodies, computed live, never a stale number.
- Zebra, curvature and draft analyses, and section planes on XY, XZ and YZ.
- Requirements in plain language — "the wall must stay above 2 mm" — re-checked on every rebuild.
Learn the tools
Step-by-step, from the help centre.
Place a box, cylinder or sphereThe Primitives group places ready-made solids — box, cylinder, cone, sphere and torus — with a few clicks or typed sizes.
Push/Pull a facePush/Pull extrudes any flat face of a solid by a distance: raise a slab into a block, sink a pocket, or thicken a wall — and the solid stays a clean B-rep.
Move (and copy) a bodyMove slides the selected bodies from one point to another, by a pointer gesture or an exact typed distance. Switch on Copy and it leaves the original where it was and places a copy instead.
Rotate a body by a typed angleRotate turns the selected bodies about an axis through a pivot you click. Set the angle by moving the pointer, or type it exactly.
Scale a bodyScale makes the selected bodies bigger or smaller by a factor, uniformly or along one axis at a time.
Sweep a profile along a path with Follow MeFollow Me drives a flat face along a path of lines or curves and leaves the solid it sweeps out: a pipe from a circle, a handrail, a moulding round a corner.
Try it on a part you already have.
Import a STEP file, push a face, put a dimension on it. 5 days, every tool, nothing to pay until you decide.
