Internal Edges By
default, the Internal Edges check box is not selected.
In this mode, the analysis is done on the surfaces.
If you select the Internal Edges check box, the analysis
is done on the faces of the surfaces.
Example:

Open
Geoboundary.CATPart from the samples directory,
select the whole part and perform the Face Checker analysis on
it leaving Internal Edges cleared,
i.e. on the surfaces, with Holes search value at 0.001mm. Two
holes are found.
Perform the transfer of Site.2. Here is what you get:
A surface has been transferred for the whole surface
is considered as erroneous.

Repeat the same operation, but with Internal Edges
checked, i.e. on the faces. Here is what you get:
Only the erroneous face has been
transferred.
Boundary
SelfIntersection
The search for selfintersections is done with a selfintersection
tolerance you can edit.
The faces with selfintersections found are displayed in yellow.
This selfintersection tolerance is a tolerance used to determine whether
the edges of the boundary are going to collide,
for example as if they were displayed as lines with this thickness:
The default SelfIntersection tolerance is 0.001mm, as in the Join
action.

Open the
SelfIntersectingEdge.CATPart from the samples directory.
Let's have a closer look at the face SurfaceWithSelfIntersectingEdges.
It
is found as selfintersecting.

Recall its supporting surface from the No Show. This is a
cylinder, that has no selfintersection.
This implies that the selfintersection problem comes from the
boundary.

Recall the Analysis of the Intersection between Boundary
Portions body from the No Show.
We have drawn a portion of both edges of the boundary, and created the
intersection between them
(portion between the two circles on the left).
Zoom in:

Select the Automatic Repair check
box and transfer the Site.1.
You can see that the face repaired (in yellow) is no longer
selfintersecting.
HoleThe Face Checker
searches discontinuities in the boundaries of faces or surfaces, like in the
Apply Geometrical Display.
Faces with holes in the boundary are displayed in blue.
If the distance between two consecutive curves
is less than the threshold value, there is no discontinuity in the boundary.
If the distance between two consecutive curves
is higher than the threshold value, there is a discontinuity.


Surface
Thin Face
The search for thin faces is done with a tolerance you can edit. Thin
faces found are displayed in pink.
This tolerance is used to determine whether the face would still exist if
its boundaries were displayed with a line of this thickness:
TransferClick
Transfer to transfer erroneous faces to a new Geometrical Set.
The name of this Geometrical Set is made of the name of the problem and of
the value of the tolerance
(e.g. SelfIntersection_0.001.1, Hole_0.01.1...).
The option Automatic Repair
is available for SelfIntersection problems only.
Whenever possible, the face is modified to
heal the selfintersecting
boundary.
