Описание

The TechDraw SectionView tool inserts a cross-section view based on an existing part view.


Sectioning an already placed view, which shows the internal holes and a hatched cut surface.
The top image shows the ANSI arrow format.
The bottom image shows the ISO arrow format.

Применение

  1. Select a part view in the 3D view or Tree view.
  2. There are several ways to invoke the tool:
    • Press the Insert Section View button.
    • Select the TechDraw → TechDraw Views → Insert Section View option from the menu.
  3. A task panel opens which will help calculate the various properties. Reasonable values for the view Direction are calculated, but these can be changed.

Properties Section View

Данные

Cut Operation

  • ДанныеFuse Before Cut (Bool): Fuse the source shapes before performing the section cut.
  • ДанныеTrim After Cut (Bool): Additionally trim the resulting shape after the section cut to remove any unwanted pieces.

Cut Surface Format

  • ДанныеCut Surface Display (Enumeration): Appearance of the 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
  • ДанныеFile Hatch Pattern (File): Full path to SVG hatch pattern file.
  • ДанныеFile Geom Pattern (File): Full path to PAT pattern file.
  • ДанныеSvg Included (FileIncluded): Full path to the included SVG hatch pattern file.
  • ДанныеPat Included (FileIncluded): Full path to the included PAT pattern file.
  • ДанныеName Geom Pattern (String): Name of the PAT pattern to use.
  • ДанныеHatch Scale (Float): Hatch pattern size adjustment.

Section

  • ДанныеSection Symbol (String): The identifier for this section.
  • ДанныеBase View (Link): The view on which this section is based.
  • ДанныеSection Normal (Vector): A vector describing the direction normal to the cutting plane.
  • ДанныеSection Origin (Vector): A vector describing a point on the cutting plane. Typically the centroid of the original part.
  • ДанныеSection Direction (Enumeration): The direction in the Base View for this section. Options: Aligned, Right, Left, Up or Down.

Вид

Cut Surface

  • ВидCut Surface Color (Color): Solid color for surface highlight. Used if ДанныеCut Surface Display is set to Color.
  • Вид (Hidden)Show Cut Surface (Bool): Show/hide the cut surface.

Surface Hatch

  • ВидGeom Hatch Color (Color): The color of the Geometric hath pattern.
  • ВидHatch Color (Color): The color of the Svg hatch pattern.
  • Вид (Hidden)Hatch Cut Surface (Bool): Hatch the cut surface.
  • ВидWeight Pattern (Float): Line weight of the Geometric hatch pattern.

Properties Base View

A Section view inherits all applicable properties of the view specified as ДанныеBase View. In the properties of this view you can change the appearance of the section line:

  • ВидSection Line Color: The section line color.
  • ВидSection Line Style: The section line style.

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

Примечания

  • Section Line Format: two section line formats are supported (as depicted above) and controlled by the Preference setting "Section Line Standard" on the Annotation tab. The ANSI option uses "pulling arrows" (known as the "traditional format" in some areas) and the ISO option uses "pushing arrows" (also known as the "reference arrow format").
  • Fuse Before Cut: the section operation sometimes fails to cut the source shapes. If Fuse Before Cut 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.
  • Trim After Cut: the section cut operation sometimes leaves behind a portion of the source shape. If Trim After Cut is true, an additional cut operation is performed on the result of the first cut which should remove any unwanted pieces.
  • Cut Surface Display: 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.

Программирование

A SectionView can be created with macros and from the Python console by using the following functions:

doc = FreeCAD.ActiveDocument
box = doc.Box
page = doc.Page

view = doc.addObject("TechDraw::DrawViewPart", "View")
page.addView(view)
view.Source = box
view.Direction = (0, 0, 1)

section = doc.addObject("TechDraw::DrawViewSection", "Section")
page.addView(section)
section.Source = box
section.BaseView = view
section.Direction = (0, 1, 0)
section.SectionNormal = (-1, 0, 0)

doc.recompute()
