Développeur de Patron Plat de Cône Oblique

Triangulez un cône circulaire à sommet décalé en une ébauche développée imprimable avec les longueurs réelles des génératrices.

Calculez la disposition, vérifiez le diagramme, puis imprimez le résultat pour l'atelier ou le chantier.

Fonctionnement

Measure height perpendicular to the base. Measure apex offset in the base plane from the circle center to the vertical projection of the apex.

The base is divided into chords and each triangular facet uses its true generator lengths. With the default 300 mm base, 400 mm height and 80 mm offset, the generators range from about 406.1 to 461.4 mm.

Exemple avec les saisies actuelles

Le résultat ci-dessus utilise exactement ces valeurs. Cet instantané est inclus à l’impression pour comparer la sortie aux mesures d’origine.

Avant d’utiliser le résultat

  • Measure from the datum or reference edge described by this tool, and do not mix inside, outside and centerline dimensions.
  • Keep inputs in the displayed units and preserve more precision than the final cutting or purchasing tolerance requires.
  • When the result is close to a limit, verify it with a test piece, field measurement, manufacturer drawing or qualified project professional.

Limites

This is a triangulated circular-edge approximation. More divisions produce a smoother edge but add layout lines. Add the seam separately, mark its orientation and verify a test pattern before production.

Questions fréquentes

What should I verify before using this result?

Recheck the physical measurements, confirm that every input uses the displayed unit, and compare the result with the applicable drawing, product specification, code requirement or test piece.

Why might the finished result differ?

Real work can include thickness, kerf, seams, tolerances, hardware allowances, installation clearances or site conditions that are outside the calculation. The limitations section identifies the main exclusions for this tool.
