Canvas filling in Hollow Objects #220

Open jthomason007 opened 3 years ago

jthomason007 commented 3 years ago

Describe the bug I have created several hollow objects on TinkerCad. When I upload the .stl file to canvas, the hollow part of the object is filled in and it is shown as solid. In a different splicer software (3d simplify) the hollow portion of the object is still there.

To Reproduce Steps to reproduce the behavior:

  1. Go to Canvas and upload an object with a portion of the inside gone and that does not touch air. (Download the one I used at the bottom, note that I had this issue with several designs.)
  2. Click on preview
  3. Adjust the slider on the right so you can see the print process.
  4. See error ie there is no longer a missing portion of the inside.

Expected behavior When you adjust the slider through the layers of the print there will be a portion of the print that will have a hollow area.

Here is the .stl of the hollow block to check out for yourself, stl files aren't accepted so I had to zip it first. block.zip
