<p>I’m back! At least for now. Today i’m answering a question about cutting circular holes in curved surfaces. I learned this technique from the great <a href="https://www.facebook.com/Kuhn-Industries-345392525548878/">Chris Kuhn</a> a few years ago and have used it ever since.
<h2 id="1">1.</h2>
<p>Start with even quads and an even mesh density.
<h2 id="2">2.</h2>
<p>Add a Circle with an amount of sides relative to the density of the surface.
<h2 id="3">3.</h2>
<p>Add a Shrinkwrap modifier to the circle, and set to project onto the surface area. (Be sure to set the direction and axis of projection.)
<h2 id="4">4.</h2>
<p>Cut necessary areas in surface and merge vertexes along the edge of the hole with the circle. (Be sure to merge to the circle to maintain the circular shape.)
<h2 id="5">5.</h2>
<p>Finish by checking geometry for errors or improper curvature.
