TechDraw SectionView/es

Descripción
The Section tool creates a cross section view based on an existing part view.



Utilización

 * 1) Select a part view in the 3D window or tree.
 * 2) Press the  button
 * 3) A dialog will open which will help calculate the various Section properties.  The dialog calculates reasonable starting points for SectionNormal and view Direction, but these may be changed after creation for special needs.
 * 4) If you make a mistake, or change your mind while setting up the Section parameters, press the  button, and you can start over.



Section

 * : The view on which this section is based.
 * : A vector describing the direction normal to the cutting plane.
 * : A vector describing a point on the cutting plane. Typically the centroid of the original part.
 * : Fuse the source shapes before performing the section cut.

Cut Surface Format

 * : Appearance of cut surface. Options:
 * Hide Hides the cut surface, only the outline will be displayed.
 * Color: Colors the cut surface using the setting of Cut Surface Color in the TechDraw preferences.
 * SvgHatch: Hatches the section cut using a hatch
 * PatHatch: Hatches the section cut using a geometric hatch
 * : Full path to SVG hatch pattern file.
 * : Full path to PAT pattern file.
 * : Full path to the included SVG hatch pattern file.
 * : Full path to the included PAT pattern file.
 * : Name of PAT pattern to use (ignored for the SvgHatch setting of Cut Surface Display).

Cut Surface

 * : Solid color for surface highlight. Used if Cut Surface Display is set to Color.

Surface Hatch

 * : Color for surface hatch lines.
 * : Line weight for surface hatch lines.

Vista de base
A Section view inherits all applicable properties of the view specified as. In the properties of the view you can change the appearance of the section line:


 * : Color for the section line.
 * : Style for the section line.

The default settings for these parameters are set via the settings Section Line and Section Line Style in the TechDraw preferences.

Scripting
TechDraw API and FreeCAD Scripting Basics.

The New Section tool can be used in macros and from the Python console by using the following functions:

Notas

 * Section Line Format: both the traditional section line format (as depicted above), and the "reference arrow method" are supported. This option is controlled by the Preference setting "Mod/TechDraw/Format/SectionFormat" (see Std_DlgParameter). 0 for traditional line, 1 for reference arrow method.
 * CutSurfaceDisplay: the cut surface can be hidden, painted in a solid color, hatched using an Svg pattern (default) or hatched using a PAT pattern. See Hatching.
 * FuseBeforeCut: the section operation sometimes fails to cut the source shapes. If FuseBeforeCut is true, the source shapes are merged into a single shape before the section operation is attempted. If you encounter problems with the section operation, try flipping this value.
