Accepted formats: *.stl

Disclaimer: Parsing shapes by STL is currently limited to geometries that are practical to draw with only circles. More complicated shapes may hit errors.

Preview

Preview the model below. Ensure that it is symmetric with respect to the drawn axis of rotation. If not, the file needs to be rotated externally.

(Note: The structure may not be aligned to the center in the preview display. This has no effect on the later processing.)

If your intended view is not available, make sure your input STL model is aligned rotated with respect to a cardinal axis.
