This example is parametric modeling at best or a configurator, not saying that is bad, just has a misleading title. I do not see any real geometry manipulation or groundbreaking CAD being attempted. Here is a viewer that Autodesk released this year using javascript.&lt;p&gt;&lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;developer.autodesk.com&amp;#x2F;&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;developer.autodesk.com&amp;#x2F;&lt;/a&gt;</text></comment>

What are you hoping to add in the future?&lt;p&gt;Our team works on goal directed design as well, but at the moment it&amp;#x27;s less of an interactive optimization tool and more of an involved job running process a la Optistruct.  One of our fun projects was a drone body as well :)&lt;p&gt;link for the interested: &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;autodeskresearch.com&amp;#x2F;projects&amp;#x2F;dreamcatcher&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;autodeskresearch.com&amp;#x2F;projects&amp;#x2F;dreamcatcher&lt;/a&gt;</text></comment>
