Descriere

Instrumentul Vizualizare adaugă o reprezentare a unuia sau mai multor obiecte pe o pagină de desen. Acesta este blocul de bază al modulului TechDraw. La plupart des autres vues proviennent de NewView.

The TechDraw View tool adds a representation of one or more objects to a Drawing page. This is the basic building block of the TechDraw workbench. Most other Views are derived in some way from View.

View will try to draw anything with a Shape property. You can select sketches, PartDesign Bodies, Draft objects etc. View will also extract any shapes from objects within a Std Part or a Std Group.

View of a solid box with hidden lines

Cum se utilizează

  1. Optionally rotate the 3D view. Unless a face is selected in the next step, the camera direction in the 3D view determines the initial value of the DateDirection property of the View.
  2. Select one or more objects in the 3D view or Tree view. When selecting in the 3D view the first selected face determines the initial value of the DateDirection property.
  3. If there are multiple drawing pages in the document: optionally add the desired page to the selection by selecting it in the Tree view.
  4. There are several ways to invoke the tool:
    • Press the Insert View button.
    • Select the TechDraw → TechDraw Views → Insert View option from the menu.
  5. If there are multiple drawing pages in the document and you have not yet selected a page, the Page Chooser dialog box opens: introduced in version 0.20
    1. Select the desired page.
    2. Press the OK button.

  • DateX (Distance): The view's horizontal position on the page. (1)
  • DateY (Distance): The view's vertical position on the page. (1)
  • DateLock Position (Bool): Prevents Views from being dragged in the Gui when true. The View can still be moved by changing X,Y properties. (1)

  • DateScale Type (Enumeration): The scale type. Options: (1)
    • Page: Use the Page's scale setting.
    • Automatic: Fit the view to the page.
    • Custom: Use the scale defined by DateScale.
  • DateScale (FloatConstant): The view will be rendered on the page in Scale:1 ratio to the Source. (1)
  • DateCaption (String): Optional short text caption. (1)

Cosmetics

  • Date (Hidden)Cosmetic Vertexes (TechDraw::PropertyCosmeticVertexList)

HLR Parameters

  • DateCoarse View (Bool): 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.
  • DateSmooth Visible (Bool): Visible Smooth lines on/off.
  • DateSeam Visible (Bool): Visible Seam lines on/off.
  • DateIso Visible (Bool): Visible Isometric(u,v) lines on/off.

Script

Vederile pot fi adăugate la Pages utilizând Python.

See also: Autogenerated API documentation and FreeCAD Scripting Basics.

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

import FreeCAD as App

doc = App.ActiveDocument
box = doc.addObject("Part::Box", "Box")

page = doc.addObject("TechDraw::DrawPage", "Page")
template = doc.addObject("TechDraw::DrawSVGTemplate", "Template")
template.Template = App.getResourceDir() + "Mod/TechDraw/Templates/A4_LandscapeTD.svg"
page.Template = template

# Toggle the visibility of the page to ensure its width and height are updated (hack):
page.Visibility = False
page.Visibility = True

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

view.X = page.PageWidth / 2
view.Y = page.PageHeight / 2

doc.recompute()
