Coincident
Use the Coincident constraint to constrain two geometric entities to coincide with each other. Depending on the type of entities selected for the constraint the following conditions may apply:
•
A vertex coincides with a straight edge if the vertex lies on the line.
•
A vertex coincides with a circular edge if the vertex lies on the circle.
•
A vertex coincides with a spline edge if the vertex lies on the spline parameterization (but possibly outside the edge’s parameter interval).
•
Two straight edges coincide if they lie on the same line.
•
Two circular edges coincide if they lie on the same circle.
•
Two spline edges coincide if they have the same spline parameterization (but possible different parameter intervals).
Add a Coincident constraint as follows:
1
Click the Coincident () toolbar button.
2
Select two vertices or edges, or one vertex and one edge.
3
Move the mouse pointer to position the coincident symbol.
4
Click to place the symbol.
The Settings window for Coincident contains the following sections:
•
Geometric Entity Selection: Change the selected entities and their type.
•
Help Points: Change the help point coordinates for the selected entities. These are used as initial guesses when making a vertex coincident with a curved edge (see Help Points).
