Not sure what to call it other than certain versions of S3D are creating problem areas in the model when sliced.
This is layer 1 of a simple box. Two versions create the spots at the arrows while one other version slices correctly.
Versions are indicated in the pictures.
This model was made in Fusion 360 and also run through Netfabb and has no errors.
S3D is creating these spots where nothing but a solid layer should be.
Thanks for any ideas on this.
