Which SketchUp versions does it run on, and how do I install it?

SketchUp 2021 through 2026, on Windows. A Ruby 2.7 syntax guard keeps the code loading on the older versions, and the same 38 plugin files are verified identical across all six installs by the bundled install checker. You can run the PowerShell installer (install.ps1) to write it into every SketchUp you have, or install dist/ramp_studio_v1.0.0.rbz by hand from Extension Manager. macOS is untested: the RBZ is plain Ruby, but the installer script is Windows-only and nobody has verified the plugin on a Mac yet.

What does the $30 cover, and can I use the ramps in commercial projects?

Yes — whatever you model with it is your geometry, and it goes into commercial work with no strings. The $30 is a one-time price for the v1.0.0 beta, sold on Gumroad, and covers one user across their own workstations, plus v1.x updates. There is no activation server and no online check today: it installs as a plain RBZ and keeps working offline. Being honest about the stage: v1.0.0 is beta, installed and green on all six SketchUp versions here, with the manual test pass in SketchUp 2026 still under way.

What can't it do yet?

Three things worth knowing before you buy. First, there is no export code: output is native SketchUp geometry (components in your model, and the RBZ package itself), so IFC and DXF, quantity and cost reports and printable PDF sheets all have to go through SketchUp's own exporters for now — they are v1.1+ roadmap items. Second, the compliance checks are practical guardrails on the common thresholds (8% warning, 25% hard error, landing over 9 m, minimum width), not a certified check against a specific national accessibility code — verify against your local regulation before submission. Third, the interface is Turkish and English only, 263 keys each; no other language is bundled.

Ramp StudioNo Slope Maths: Draw a Line, and a Railed Ramp With a Checked Slope Is Ready Instantly

When someone asks about the slope, you point to the number on screen, not a calculator. Path-based ramps — straight, L/U/Z, circular, spiral, helical — with 8 railing types, kerbs and anti-slip strips, re-solved live when any number changes.

Left: the job by hand. Right: the same job with the plugin.

Ramp Studio

Every feature, at a glance

What the plugin does for you, drawn rather than listed.

Any line becomes a ramp

Point at any line, arc or curve in your model, or pick one of 13 path generators; even on a full helix the width stays constant and the deck never tilts.

Slope three ways, always in sync

Type a percentage (8%), a ratio (1:12.5) or degrees (4.57°) and the other two follow; width, run, rise and slope solve for one another.

Inside the rules, without the maths

An accessibility warning past 8%, a hard error past 25% and a landing on runs over 9 m; slope, rise and walking distance read out as you draw.

8 railing types

Metal, glass, tube, double tube, vertical or horizontal bars, minimal or timber, left, right or both sides; the handrail runs on 300 mm by default.

From kerbs to anti-slip strips

Five edge details: kerb, side wall, band, anti-slip strips and expansion joints, each with its own side, size and material.

Change a number, the ramp follows

Select the ramp and the panel binds to it; slope, width, railings or kerbs, every change lands in the model at once and one Ctrl+Z undoes it.

Hand-modelling one ramp with railings

Drag me

01
Any Curve, a Clean Ramp
Any line, arc or curve becomes the ramp. The sweep keeps the deck upright and the width constant — even on a full helix. Even the boldest form stays as you drew it.
02
No Fear of Changes
Select the ramp and the panel binds to it. Slope, width, railings, kerbs — every change re-solves live, one Ctrl+Z undoes it. Try anything.
03
Inside the Rules, Without the Maths
You never do the maths: slope, ratio, angle, rise, run and walking distance are read out as you build — a warning past 8%, a landing past 9 m.

The technical bit

For the people who read the manual first.

Works with: SketchUp 2021 · SketchUp 2022 · SketchUp 2023 · SketchUp 2024 · SketchUp 2025 · SketchUp 2026 · Windows
Version: v1.0.0
Interface languages: tr · en

13 parametric path generators — L/U/Z turn, switchback, landing run, circular, spiral, helix, ellipse, double spiral, expanding, narrowing, multi-floor — or point it at any line, arc or curve already in your model; the path is stored in the ramp's own parameters, so the ramp rebuilds even after the source geometry is deleted.
A custom sweep engine that never calls Follow Me: path sampling to minimum-twist local frames to profile sweep. Width stays constant and the deck stays upright on arcs, circles, ellipses, spirals, helices and free 3D curves.
Slope is entered in three interchangeable notations that stay synchronised — percent (%8), ratio (1:12.5) and degrees (4.57°) — and width, horizontal run, rise and slope solve for one another.
Compliance checks with real warnings and errors: accessibility warning above 8%, hard failure above 25%, narrow-width warning, mandatory landing on runs longer than 9 m. The info panel reports slope, ratio, angle, rise, horizontal run, walking distance, width, minimum width, landings, railing, turn radius and footprint area.
8 railing types (metal, glass, tube, double tube, vertical bars, horizontal bars, minimal, timber) with left/right/both sides, post spacing, vertical/normal/angled post modes, glass thickness, infill spacing, uniform edge clearance across all types, and a handrail end extension defaulting to 300 mm (adjustable 0-1500 mm).
Post base details: square base plate or round flange with four anchor bolts, laid parallel to the sloped deck and kept inside the concrete edge automatically.
5 edge-detail types — kerb, side wall, band, anti-slip strips and expansion joints — each with its own side, dimensions and material.
Three elevation modes for path ramps (follow the path, constant slope, start+end levels) plus landing ranges where slope drops to zero. Placement is two clicks: click the start point, drag for direction, with live preview and typed length through the VCB (12m, 1150 and 45cm all parse).
Live parametric editing: select a ramp and the panel binds to it, changes hit the model instantly, and the whole session collapses to a single Ctrl+Z. Scaling a ramp with the Scale Tool is detected — X maps to length, Y to width, Z to height — then the transform is rigidified and the geometry regenerated parametrically.
Built to be maintained: 50 presets in 5 categories, 363 tests across 19 suites, 263 translation keys in each of tr.json and en.json, edge softening by dihedral angle (30° for deck and details, 40° for tube and railing) so curved ramps show no section seams, an in-panel error console with level filter plus a log at Plugins\ramp_studio_log.txt, a Ruby 2.7 syntax guard and an install verifier that compares version, file count and MD5 across every SketchUp install.
