VISI Modelling – Splitting
8. SEARCH SILHOUETTE
This command can be used to calculate the split line as a first operation, but it requires
that the solid already have edges corresponding to the required split line. In this case the
edges are identified and managed as split line edges. Therefore if the split line edges do
not lie exactly on the edge of a face it is not recognised as a split line edge.
This function is generally used to refine the results obtained from the other split line
functions.
When analysing all the edges of a solid, this function keeps only the edges that belong to
the silhouette curve and will delete all the others. This is often very useful as the Imprint
Shadow function may create some unnecessary or redundant edges. By using the Search
Silhouette all the edges that do not belong to the silhouette curve are deleted from the
body.
9. EDIT
Using the edit function it is possible to add or remove edges from the split line tree. Any
new edge selected will be treated as a split line edge and any existing split line edge
selected will be removed from the tree list. Using this function it is possible to manually
remove any redundant edges.
10. IMPRINT SEGMENT
This function allows a segment to be imprinted between two chosen points on any
selected face(s). It is necessary to specify the direction in which the segment will be
imprinted. The imprinted edges are managed as Split Line edges, and therefore visible in
the split line tree
11. UNMARK BODIES
This function will delete all edges belonging to the Split Line list.
12. UNMARK FACES
This function will remove the Split Line edges belonging to the selected face(s).
13. ANALYZE EDGES
This function will display the edges of the Split Line result in the tree-view
14. ANALYZE FACES
This function will display the resultant faces split with the user defined split line in the treeview.
If only two face sets are present, the splitting simulation can be run using the slider
bar.
