TechDraw View/es

Descripción
La herramienta Vista añade una representación de uno o más objetos a una página de Dibujo. Este es el elemento básico del módulo TechDraw. La mayoría de las otras Vistas se derivan de alguna manera de NuevoVista.



Utilización

 * 1) Select one or more objects (Body, App::Part, Part::Feature, Draft object, ... See Notes) in the 3D view or Tree view.
 * 2) If you have multiple drawing pages in your document, you will also need to select the desired page in the tree. Use the  to select multiple items in the tree.
 * 3) Press the  button

View will try to draw anything with a property. You can select Draft objects and PartDesign Bodies also. View will also extract any shapes from objects within an App::Part container or a Group.

Datos

 * : The view's horizontal position on the page. (1)
 * : The view's vertical position on the page. (1)
 * : Prevents Views from being dragged in the Gui when true. The View can still be moved by changing X,Y properties. (1)
 * : Counterclockwise rotation of the View on the page in degrees. (1)
 * : "Document": use the Page's scale setting. "Custom": use a scale unique to this view. "Automatic": fit view to page. (1)
 * : A view will be rendered on the page in Scale:1 ratio to the Source. (1)
 * : Optional short text caption.


 * : If true, TechDraw will use a polygon approximation to calculate drawing geometry. If false, TechDraw will use a precision algorithm. CoarseView can be much faster for complex models. The quality of the drawing is reduced, since every curve is approximated as a series of short line segments. Vertices are not displayed in CoarseView since each short segment would result in two new Vertices and the display becomes cluttered. Linear Dimensions can be added to a CoarseView, but are unlikely to be useful.
 * CoarseView is affected by an upstream bug in OCCT (#3332) which causes the View's position on the Page to be slightly off from the specified X,Y values.


 * : Visible Smooth lines on/off.
 * : Visible Seam lines on/off.
 * : Visible Isometric(u,v) lines on/off.
 * : Hidden lines on/off.
 * : Hidden Smooth lines on/off.
 * : Hidden Seam lines on/off.
 * : Hidden Isometric(u,v) lines on/off.
 * : Number of Isometric(u,v) lines to draw on each face.


 * : Links to the drawable objects to be depicted.
 * : Links to the drawable objects in an external file.
 * : this vector controls the direction from which you are viewing the object. +X is right, -X is left, +Y is rear, -Y is front (looking into the screen), +Z is up and -Z is down. So a Front view is (0,-1,0) and an isometric view is (1,-1,1). (1)
 * : this vector controls the rotation of the view around the Direction. . (1)
 * : True for perspective projection, false for orthogonal projection.
 * : Distance from camera to projection plane for perspective projections. Needs to be adjusted to fit the object. Too far and the perspective is lost, too close and the object is distorted.

(1) these properties are common to all View types.

View

 * : Always show View Label if true.
 * : The thickness of visible lines. See Line Groups.
 * : The thickness of hidden lines, if enabled.
 * : The thickness of isometric(u,v) surface lines and Dimension lines.
 * : not implemented yet.
 * : Circle/arc center marks on/off.
 * : Circular arc center mark size adjustment, if enabled.
 * : Show a horizontal centerline through view.
 * : Show a vertical centerline through view.
 * : Show/hide section line if applicable.
