  2. SolveSpace - Wikipedia

    en.wikipedia.org/wiki/SolveSpace

    A workplane is plane with an origin for the new sketch where the SolveSpace draws entities. Users can make it active and draw basic primitives such as lines, circles, arcs, dots, and other points of references on the workplane, and constrain them to specific dimensions and relations. [15] SolveSpace can split intersecting entities via a ...

  3. SolidWorks - Wikipedia

    en.wikipedia.org/wiki/SolidWorks

    SolidWorks (stylized as SOLIDWORKS) is a brand within Dassault Systèmes that develops and markets software for solid modeling computer-aided design (CAD), computer-aided engineering (CAE), 3D CAD design, collaboration, analysis, and product data management. [2] The company introduced one of the first 3D CAD applications designed to run on a ...

  4. OpenVSP - Wikipedia

    en.wikipedia.org/wiki/OpenVSP

    A workspace window and a "Geometry Browser" window open. The workspace is where the model is displayed while the Geometry Browser lists individual components in the workspace, such as fuselage and wings. These components can be selected, added or deleted, somewhat like a feature tree in CAD software such as Solidworks. When a component is ...

  5. Four-bar linkage - Wikipedia

    en.wikipedia.org/wiki/Four-bar_linkage

    Generally, the joints are configured so the links move in parallel planes, and the assembly is called a planar four-bar linkage. Spherical and spatial four-bar linkages also exist and are used in practice. [1] A pumpjack's main mechanism is a four-bar linkage

    Thus, the general offset surface shares the same tangent plane and normal with and (()). That aligns with the nature of envelopes. That aligns with the nature of envelopes. We now consider the Weingarten equations for the shape operator , which can be written as ∂ n → = − ∂ x → S {\displaystyle \partial {\vec {n}}=-\partial {\vec {x}}S} .

  7. Propeller - Wikipedia

    en.wikipedia.org/wiki/Propeller

    Skew is the tangential offset of the line of maximum thickness to a radius The propeller characteristics are commonly expressed as dimensionless ratios: [31] Pitch ratio PR = propeller pitch/propeller diameter, or P/D; Disk area A 0 = πD 2 /4; Expanded area ratio = A E /A 0, where expanded area A E = Expanded area of all blades outside of the hub.

  8. Z-fighting - Wikipedia

    en.wikipedia.org/wiki/Z-fighting

    As the distance between near and far clip planes increases, and in particular the near plane is selected near the eye, the greater the likelihood exists that z-fighting between primitives will occur. With large virtual environments inevitably there is an inherent conflict between the need to resolve visibility in the distance and in the ...

  9. Hyperplane - Wikipedia

    en.wikipedia.org/wiki/Hyperplane

    In geometry, a hyperplane of an n-dimensional space V is a subspace of dimension n − 1, or equivalently, of codimension 1 in V.The space V may be a Euclidean space or more generally an affine space, or a vector space or a projective space, and the notion of hyperplane varies correspondingly since the definition of subspace differs in these settings; in all cases however, any hyperplane can ...
