Description

The ActiveView tool inserts a copy of a 3D window into a drawing page.

A simple view from the 3D model that doesn't perform any complex calculation.

Usage

  1. Navigate to the 3D window you wish to copy.
  2. If you have multiple drawing pages in your document, you will also need to select the desired page in the tree.
  3. Press the Insert Active View button
  4. A dialog will open to allow you to specify the size, border and background color of the copy.

Notes

  • Active views are static once generated, they are never updated with changes to the 3D model.
  • ActiveView behind the scenes is a Symbol View. Its DataScale Type is therefore always initialized as Custom.
  • This tool is still somewhat Experimental.

Properties

See Symbol

Dialog Fields

  • DataWidth: The width of the generated view.
  • DataHeight: The height of the generated view.
  • DataBorder: The amount of empty space to be left around the view (but within Width x Height).
  • DataBackground: Show or hide a background.
  • DataBackground Color: Color to paint the background, if applicable.
  • DataLine Width: Thickness of individual lines in the view.
  • DataRender Mode: The render mode of the library Coin3d. The possible modes are
    • AS_IS Render primitives as they are
    • WIREFRAME Render polygons as wireframe
    • POINTS Render only the vertices of the polygons and lines
    • WIREFRAME_OVERLAY Render a wireframe overlay in addition to the AS_IS mode
    • HIDDEN_LINE As WIREFRAME, but culls lines which would otherwise not be shown due to geometric culling
    • BOUNDING_BOX Only show the bounding box of each object

Scripting

See also: TechDraw API and FreeCAD Scripting Basics.

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

import TechDrawGui
TechDrawGui.copyActiveViewToSvgFile(Gui.ActiveDocument.ActiveView,"myFile.svg")
