Construct Breakline
Construct Breakline tool constructs or removes breaklines between existing points in a model. Breaklines effect the way a model is triangulated. In this context, a breakline is a triangle edge connecting two points in the surface model. Thus, constructing or removing breaklines does not effect the actual points in a model, but it changes the way those points are connected by the triangle network.
The tool prompts you to identify two points in a surface model. A breakline is constructed, if the two points are not already connected by a breakline of the same type. If the two points are connected by a breakline of the same type, this tool removes the existing breakline.
To construct or remove breaklines:
1. Select the Construct Breakline tool.
The Construct Breakline dialog opens:
2. Select a view for breakline display with a data click inside the view.
Breaklines inside the selected view are highlighted with colors according to the breakline type.
3. Define settings in the dialog.
4. Identify a first point in the model.
5. Identify a second point in the model.
A breakline is constructed or removed. You can continue with steps 3 or 4.

Attempting to construct a breakline may fail because: •The new breakline would intersect an existing breakline. Breaklines can not intersect each other. Try to remove the old breakline first. •The two points are far apart. Try to construct a shorter breakline first. •The breakline would break through a very large number of triangle edges. Try to construct a shorter breakline first. |
