The TechDraw View tool adds a representation of one or more objects to a Drawing page. introduced in version 1.0: It can create a Projection Group Item (a single view), a Projection Group, a Spreadsheet View, an Arch View, a Symbol or an Image View.

In version 0.21 and below the tool can only create a Part View, which is very similar to a Projection Group Item.

A Part 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()
