Anyway, the option we&#8217;re looking for is the Performance -> 3D accuracy option. This is defaulted to 0.2, however it can be increased to provide higher accuracy STL outputs (yes it affects exports as well as rendering, so this can be a performance hit on low end systems).<\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/lab.rapternet.us\/wp-content\/uploads\/2022\/02\/image-31.png\" alt=\"\" class=\"wp-image-1793\" width=\"674\" height=\"499\" srcset=\"https:\/\/lab.rapternet.us\/wp-content\/uploads\/2022\/02\/image-31.png 997w, https:\/\/lab.rapternet.us\/wp-content\/uploads\/2022\/02\/image-31-300x222.png 300w, https:\/\/lab.rapternet.us\/wp-content\/uploads\/2022\/02\/image-31-768x569.png 768w\" sizes=\"auto, (max-width: 674px) 100vw, 674px\" \/><figcaption>Default accuracy<\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"988\" height=\"733\" src=\"https:\/\/lab.rapternet.us\/wp-content\/uploads\/2022\/02\/image-32.png\" alt=\"\" class=\"wp-image-1794\" srcset=\"https:\/\/lab.rapternet.us\/wp-content\/uploads\/2022\/02\/image-32.png 988w, https:\/\/lab.rapternet.us\/wp-content\/uploads\/2022\/02\/image-32-300x223.png 300w, https:\/\/lab.rapternet.us\/wp-content\/uploads\/2022\/02\/image-32-768x570.png 768w\" sizes=\"auto, (max-width: 767px) 89vw, (max-width: 1000px) 54vw, (max-width: 1071px) 543px, 580px\" \/><figcaption>Updated accuracy<\/figcaption><\/figure>\n\n\n\n<p>With our accuracy increased to 0.01, we can get some side by side comparisons of before and after.
