Descriere
Un solid parametric este Elipsoidul care este disponibil din dialogul Create Primitives în Atelierul de lucru Part.
The 
Part Ellipsoid command creates a parametric Ellipsoid solid.
Forma produsă este limitată în FreeCAD ca fiind un sferoid solid (opțional trunchiat), forma pe care ați crea-o prin rotirea unei elipse în jurul axei sale. Implicit este a oblate_spheroid, forma pe care ați crea-o prin rotirea unei elipse în jurul axei sale minore. Parametrii pot fi modificați pentru a forma aprolate_spheroid.
Sferoidul implicit din FreeCAD va avea un cerc pentru orice secțiune transversală paralelă cu planul xy. Secțiunea transversală paralelă cu celelalte două planuri va fi o elipsă.
În mathematică, un Ellipsoid ar avea o secțiune eliptică în toate cele trei planuri.
Usage
A parametric Ellipsoid solid is available from the Create Primitives dialogue in the Part workbench.
- Switch to the
Part Workbench - Access the Ellipsoid command several ways:
- Through the Create Primitives dialogue, pressing the
CreatePrimitives button located in the Part toolbar - Using the Part → Create Primitives → Ellipsoid entry in the Part menu
- Through the Create Primitives dialogue, pressing the
Proprietăți
- Radius 1, implicit semiaxa minoră paralelă la axa Z,
- Radius 2, implicită semiaxa majoră paralelă la planul XY,
este, de asemenea, raza maximă a secțiunii circulare
- Angle 1, trunchierea inferioară a elipsoidului, paralelă cu secțiunea transversală circulară (-90 grade într-un sferic complet)
- Angle 2, trunchierea superioară a elipsoidului, paralelă cu secțiunea transversală circulară (90 de grade într-un sferic complet)
- Angle 3, unghiul de rotație a secțiunii transversale eliptice (360 degrees in a full spheroid)
