Match edges
Menu: Facets Icon: No short cut
Matches all unmatched triangle edges within a defined tolerance
The surface description (as well as the volume description) of a model is incomplete as long as
the triangle mesh contains unmatched edges. An unmatched edge means that at this point, the
reference link between one triangle and the neighboring triangle is missing. By matching such
edges the triangle mesh becomes self contained and a useable model is generated.
In order to match an unmatched edge, a second unmatched edge is searched for within a
predefined distance. This distance is referred to as (matching) tolerance.
For matching, both edges are displaced so that they become congruent with each other. This
causes small deviations in the triangle mesh from the original geometry. Therefore, the matching
tolerance should not be set too high.
HINT: The default values are based on the experience of many years. Normally, they do not need
to be adjusted. It is recommended to use the function Fill holes if there are still some unmatched
edges left.
Dialog Match edges
User Tolerance
Start matching: Start tolerance that is used in the first step to
find a suitable neighboring edge.
End matching: Maximum tolerance. The start tolerance is
increased stepwise up to the maximum value.
Increment: This value is added iteratively to the tolerance value
until a neighboring edge is found.
Matching parameters
Use only start tolerance: Only one matching pass is
implemented. The defined start tolerance is used.
Use only system tolerance: Only one matching pass is
implemented. The tolerance value is defined automatically (1/10 of the length of the shortest
edge of the model).
