Elliptical Spear Top Fence Panel | Fabrication Drawings
Fence panel whose vertical spear tips trace a half-ellipse arc across the top -- tallest in the middle (convex) or dished (concave) -- on a straight top rail. Heritage arched-palisade aesthetic, matching the elliptical spear-top gates for a continuous run. Level only. Each spear is a different length; a dedicated Spear Heights page lists every overhang plus a foot-to-tip cut-list.
Configure Elliptical Spear Top Fence Panel dimensions and download professional A4 PDF fabrication drawings with orthographic views and dimension lines. No CAD software needed. Sub-millimetre precision from a true 3D solid model.

Frequently Asked Questions
What opening widths does the Elliptical Spear Top Fence Panel support?
The Elliptical Spear Top Fence Panel accepts opening widths from 100 mm to 6,000 mm. Enter your exact site measurement and the engine recomputes all frame members, battens or slats, and dimension lines to match.
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 Fence Panel 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 Fence Panel?
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.
