<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">I’d hate to lead you into an unnecessarily time-consuming path, but I have on rare occasion found it helpful to approach defining complex building shades as
exterior wall sections under a dummy space, which themselves can be defined referencing a polygon, which in turn can be defined in (relative) XYZ point coordinates… What you functionally lose along the way is the ability to assign a shading schedule or otherwise
alter the opacity of the resulting “shade.”<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">Disclaimer: Defining shades with exterior wall sections is likely going to be time consuming, however you slice it. Like anything worth doing, right =)?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">If you’re interested in pursuing this, you should first consider whether the shade you’re emulating can be represented/approximated in 2D. I did a writeup
once (full discussion attached) showing how one can apply the concept above to represent a complex, repeating shape to pick up the shading of a superstructure. Here’s an illustration showing the end-result:<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">To up the ante, with another tier of effort you can approach approximating 3D shapes with polygonal exterior wall sections… but I would sooner advise strongly
considering whether a 2D equivalent can be defined, or if you might better invest your time learning a more complex-geometry-compliant energy modeling software (I keep meaning to do this!). Following is a visual of using polygonal exterior wall sections as
shades to achieve a 3D shape – this was not a small amount of work:<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">A couple folks have, in years past, developed impressive looking export tools (from the likes of sketchup, revit and so forth) that at least appear to automate
production of polygons for complex geometries in eQuest… I’ve never seen any of these freely distributed nor test-driven any such tool/process myself, so I can’t endorse further other than to note they’re out there and might be available, for a cost.<o:p></o:p></span></p>
