Beskrivning

The Draft Shape2DView command creates 2D projections from selected objects, usually 3D solids or Arch SectionPlanes. The projections are placed in the 3D view.

Draft Shape2DView projections can be displayed on a TechDraw Workbench page using the TechDraw DraftView command. Alternatively the TechDraw Workbench offer its own projection commands. But these create projections that are only displayed on the drawing page and not in the 3D view.

Projection of solid shapes onto the XY plane

Bruk

  1. Optionally rotate the 3D view. The camera direction in the 3D view determines the projection vector. For example, a top view will project onto the XY plane. The projection vector is ignored for projections created from Arch SectionPlanes.
  2. Optionally select one or more objects.
  3. There are several ways to invoke the command:
    • Press the Shape 2D view button.
    • Select the Modification → Shape 2D view option from the menu.
  4. If you have not yet selected an object: select an object in the 3D view.
  5. The projected objects are created on the XY plane.

How to produce plans and sections with different linewidths

Drawings with different linewidths for viewed and cut lines can easily be produced by using two shape2Dview objects from a same Arch SectionPlane. One of the shape2Dview objects has its projection mode set to Solid, which renders the viewed lines, and another set to Cut lines or Cut faces to render the cut lines. The two shape2Dviews are then placed at the same location, one on top of the other.

Properties

A Draft Shape2DView object is derived from a Part Part2DObject and inherits all its properties. It also has the following additional properties:

Scripting

Skript

To create a 2D projection use the make_shape2dview method (introduced in version 0.19) of the Draft module. This method replaces the deprecated makeShape2DView method. 

shape2dview = make_shape2dview(baseobj, projectionVector=None, facenumbers=[])

Change the ProjectionMode property of the created object if required. It can be: "Solid", "Individual Faces", "Cutlines", "Cutfaces" or "Solid faces".

Example: 

import FreeCAD as App
import Draft

doc = App.newDocument()

box = doc.addObject("Part::Box", "Box")
box.Length = 2300
box.Width = 500
box.Height = 1000

shape1 = Draft.make_shape2dview(box)

shape2 = Draft.make_shape2dview(box, App.Vector(1, -1, 1))

shape3 = Draft.make_shape2dview(box, App.Vector(-1, 1, 1), [0, 5])
shape3.ProjectionMode = "Individual Faces"

doc.recompute()
