The Node By Intersect tool allows you to create nodes when you are in the process of creating a new model or adding to an existing model. To access this tool, click ( ).
The Create Nodes by Intersect command is used to create a node at each intersection of two curves.
Select two curves that intersect. A new node will be created at each intersection of the curves.
Move your cursor to the model and rubber-band select, or click on the existing curves. Alternatively, type the curve number (e.g. C1) in the input box.
In some cases you have the option to Create as modeling entity. No properties will be assigned. This option may be appropriate if, for example, you are creating curves to construct a region. You must assign properties to the region, but you don't need to assign properties to the curves.
