Frameless Glass Curved Run | Fabrication Drawings
A run of frameless toughened-glass panes bent to one radius in plan, for curved landings, voids and fancy staircases: set out around the curve by sweep angle or girth with equal or fixed-girth panes, the gaps and end gaps measured around the curve. Level, or helical so the glass climbs with a curved stair, its pitch entered as a helix angle or a tread rise and going at the walkline. Held by spigots (core drilled or on base plates turned square to the glass), a rolled base channel, or face fixed on standoff pins into a curved slab edge, with an optional interlinking handrail or slotted cap rail rolled to the curve. Includes the plan with radius, chord, rise and sweep, and a glass template sheet per pane.

Frequently Asked Questions
What do I get in the drawing pack?
Each drawing pack is an A4 PDF with orthographic views (front elevation, side elevation, top view, and isometric), full dimension lines, extension lines, and a professional title block. You also get a live 3D preview in the browser and optional STEP file export for CAD software.
Can I use this drawing for fabrication?
Yes. Dimensions are computed to sub-millimetre precision from a true 3D solid model, not approximated from a template. Print the PDF at actual size, hand it to your fabricator, and build from it. Change any input and the entire drawing regenerates in about 60 seconds.
How long does it take to generate a Frameless Glass Curved Run drawing?
Around 60 seconds end-to-end. Geometry computation runs server-side in a CadQuery process with a 30-second per-request timeout; PDF rendering and download account for the rest. If you change a dimension, regeneration takes the same ~60 seconds — there is no manual redrafting step.
Can I save and reload my dimensions for the Frameless Glass Curved Run?
Yes. The free Explorer tier keeps 1 saved drawing, so you always have somewhere to land between visits. Fabricator saves every drawing you make and reloads the configurator in one click, so you can revise a quote, regenerate a clean PDF, or branch a design for a similar customer without re-typing dimensions.
