<h2><span class="mw-headline" id="Purpose_and_principles">Purpose and principles</span></h2>
|
|
<p>This is a software development project aimed to implement a Unit-system framework into FreeCAD.
|
|
</p><p>The development steps are planed here (Next actions) and tracked in the Issue tracking system to get a well formed change log: <a rel="nofollow" class="external text" href="http://apps.sourceforge.net/mantisbt/free-cad/my_view_page.php">Issue tracker</a>
|
|
</p>
|
|
<h2><span class="mw-headline" id="Outcome">Outcome</span></h2>
|
|
<p>It will enable FreeCAD to handle wired measurement systems, like the imperial system, and complex compound <a rel="nofollow" class="external text" href="Units.html">SI</a> 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).

|

<p>Upgrading the parser to handle and generate signatures as discussed in the <a href="Units.html" title="Units">Units</a> article.

<h3><span class="mw-headline" id="Properties">Properties</span></h3>
|
|
<p>Changing the properties form e.g. PropertyLength to PropertyUntit with a unit signature.
|

</p><p>Eventually a property editor for the PropertyUntit.

<ul><li> Upgrading workbenches to use the Units framework. I would start with Sketcher and PartDesign and go subsequently further...</li>
|
|
<li> Documenting that upgrade process so other people can do the same with other workbenches --<a href="https://www.freecadweb.org/wiki/index.php?title=User:Yorikvanhavre" class="mw-redirect" title="User:Yorikvanhavre">Yorikvanhavre</a> 13:13, 28 November 2011 (UTC)</li></ul>
