Elliptical Spear Top Double Swing Gate | Fabrication Drawings
Double-leaf driveway gate whose vertical spear tips trace a half-ellipse arc across each leaf -- tallest in the middle (convex) or dished (concave) -- on a straight top rail. Each leaf resolves its own arc independently, mirrored either side of the meeting line, so both leaves read back at full height at the outer posts AND the meeting stiles. Heritage arched-palisade aesthetic. Each spear is a different length; a dedicated Spear Heights page lists every leaf's overhangs plus a foot-to-tip cut-list.

Frequently Asked Questions
What opening widths does the Elliptical Spear Top Double Swing Gate support?
The Elliptical Spear Top Double Swing Gate accepts opening widths from 500 mm to 12,000 mm. Enter your exact site measurement and the engine recomputes all frame members, battens or slats, and dimension lines to match.
What heights can the Elliptical Spear Top Double Swing Gate be?
Heights range from 600 mm to 3,000 mm. Left and right heights can differ to accommodate raked or sloped ground. The drawing recomputes automatically for any height within the range.
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 Elliptical Spear Top Double Swing Gate 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 Elliptical Spear Top Double Swing Gate?
Yes, on the Fabricator tier. Saved jobs store every input you entered and reload 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. The free Explorer tier doesn't persist jobs, but you can still copy your inputs out manually.
