Create rose diagrams in Inkscape from survex .3d files

May 2020: completely updated for Inkscape 1.0

Compute a passage orientation rose diagram from a survex .3d file and render as SVG into the current document.

Installation

Copy the files rose_create.py and rose_create.inx into your local Inkscape extension folder: $HOME/.config/inkscape/extensions/ on unix, or %APPDATA%\inkscape\extensions\ on Windows. There are no dependencies since the extension natively reads the binary .3d file format (v8 only, which is generated by survex versions from 1.2.7).

Usage

The extension appears under Extensions → Render → Rose diagram from .3d file…

This brings up a small dialog box with options to adjust sizes, set the number of sectors, choose whether to render the diagram in color or black and white, and to set a title. If the title is left blank, a default title is extracted from the .3d file. Live preview is available.
