Description

The TechDraw ComplexSection tool inserts a cross-section view based on an existing part view and a profile.

Usage

  1. Select a part view and a profile object in the 3D view or Tree view. Profiles are typically Sketches, but any object whose shape can be made into a wire will work.
  2. There are several ways to invoke the tool:
  3. A task panel will open which will help calculate the various properties. Reasonable values for the view Direction are calculated, but these can be changed.

Data

Cutting Tool

  • DataCutting Tool Wire Object: The document object whose shape will be used to generate the cutting profile.
  • DataProjection Strategy: Controls how the cut is performed and how the result is projected on the page:
    • Offset: Performs a simple cut of the Source shape and projects the result.
    • Aligned: Cuts the Source shape using a tool created from each segment (edge) of the cutting profile. The results of each cut are projected in a vertical or horizontal array, depending on the orientation of the cutting profile.
    • NoParallel: As Aligned, but profile segments which are parallel to the view direction are skipped.

Notes

Scripting

See also: Autogenerated API documentation and FreeCAD Scripting Basics.

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

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

view = doc.addObject("TechDraw::DrawViewPart", "View")
page.addView(view)
view.Source = box
view.Direction = (0.0, 0.0, 1.0)

section = doc.addObject("TechDraw::DrawComplexSection", "ComplexSection")
page.addView(section)
section.BaseView = view
section.CuttingToolWireObject = profile
section.Direction = (0.0, 1.0, 0.0)
section.SectionNormal = (-1.0, 0.0, 0.0)
