title: Why the latest version of forge viewer V7.58 is only working with buffer geometry
body: <p>I recently started working on forge viewer. As the version of forge viewer I was using in my project was 7.2 and now I have updated it to V 7.58. Only the issue now I'm facing is, I'm unable to create extrude geometry with current version V 7.58.</p>
  <ul>
  <li>What the situation is -- I want to create lines (i.e. tubes with thickness, not the lines only) in the scene, So I have to create extrude geometry for that , but unable to create. I have verified with shape and material but not a problem with them. And if I try to create buffer geometry directly (i.e. excluding ExtrudeGeometry), then there is no any issue. Geometry is getting created.</li>
  <li>At at the lower versions of Forge viewer, I'm not facing such kind of issue. Its all working fine, extrude geometry also created fine.</li>
  <li>So my question is, Why latest version of forge viewer i.e. V7.58 is only working with buffer geometry ? Is this the issue with latest version of forge viewer really? If it is, How can I resolve it? Is there any source of documentation or anything else which will be helpful for such?</li>
  </ul>
