    <description>&lt;P&gt;Reference planes have directionality in that one side is considered the front or positive build surface. &amp;nbsp;The way we draw a reference plane dictates that direction. &amp;nbsp;Drawing the extents of a reference plane from top&amp;nbsp;to bottom&amp;nbsp;in plan results in a different plane than if it were drawn from bottom&amp;nbsp;to top. &amp;nbsp;For the plane drawn top&amp;nbsp;to bottom, the positive direction for an extrusion built on that plane will extend to the right. &amp;nbsp;For a reference plane drawn from bottom to to, the positive direction for the extrusion will extend to the left. &amp;nbsp;This has huge implications when building families. It would help if we had flip controls to fix the erroneously created reference planes.&lt;/P&gt;

      <description>&lt;P&gt;Revit has much more problems with reference planes than most people are aware...&lt;BR /&gt;To show you, just try to model a traditional Roof and a Sloped Glazing,&amp;nbsp;one by footprint and by extrusion (use different panels, it will be more clear). Then mirror the 4 roofs twice (vertical and horizontal) and compair the results. You will be surprised of the result.&lt;/P&gt;</description>
