Delete contours without surface: If this option is activated, contours without any computable
surface are filtered and deleted during slice generation.
Contours without surface can originate in walls and vertices of a part that do not have a wall
thickness. These should be deleted as they might induce errors when the slice is built.
Connect Parameters
Gaps and holes within the surface of the parts may result in open contours when generating
slices. This may lead into problems when building the part caused by the missing differentiation
between the material surface and the part environment.
Auto connection: A search algorithm tries to close gaps within the contour using a definable
range.
Delete open contours: If activated open contours are deleted when they remain open after using
the auto connection function. If the option is unselected open contours are just being connected
on the open ends. So the contours are being closed in any case. A correct representation of the
model geometry is not guarantied.
In addition contour intersections and degenerated edges are automatically removed. This errors
originate from overlapping or intersecting triangles in the triangle surface. Incorrect attached
surfaces within the CAD model are the origin of such triangles.
Because of the orientation of the contour a contour intersection may lead into errors when
building the slice. A correct differentiation between the material surface and the environment
may not be possible. Contours with intersections are cut at the intersection and split into
contours that are minimally different (0.001 mm).
Additionally degenerated contour edges are automatically detected and filtered. (i.e. fig. 3 - 4).
