Units project

** This roadmap is probably obsolete. For more information see Development roadmap.
If you are not involved with the development discussed here:
!!! PLEASE DO NOT EDIT OR TRANSLATE !!! **

This project is toward the implementation of a decent Units system in FreeCAD. It follows the rules of the [http://en.wikipedia.org/wiki/GTD#GTD_methodology| Getting things done] process. The projects are collected in the Development roadmap.

Purpose and principles

This is a software development project aimed to implement a Unit-system framework into FreeCAD.

The development steps are planed here (Next actions) and tracked in the Issue tracking system to get a well formed change log: Issue tracker

Outcome

It will enable FreeCAD to handle wired measurement systems, like the imperial system, and complex compound SI units. Also handle the import/export formats which are able to transport Units (like STEP). And allow scaling based on assumptions of Units (mm->m, m->in).

Brainstorming

Lots of discussion was done here: http://forum.freecadweb.org/viewtopic.php?f=10&t=1616

And lot of information you'll find in the Units article.

Organizing

Upgrading units parser

Upgrading the parser to handle and generate signatures as discussed in the Units article.

Properties

Changing the properties form e.g. PropertyLength to PropertyUntit with a unit signature.

Eventually a property editor for the PropertyUntit.

Workbenches

  • Upgrading workbenches to use the Units framework. I would start with Sketcher and PartDesign and go subsequently further...
  • Documenting that upgrade process so other people can do the same with other workbenches --Yorikvanhavre 13:13, 28 November 2011 (UTC)

Next actions

  • Upgrading units parser (jriegel)
