Coincidence-type constraints are
used to align elements. |
| |
Depending on the selected
elements, you may obtain concentricity, coaxiality or coplanarity. The
tolerance i.e. the smallest distance that can be used to differentiate two
elements is set at 10 -3 millimeters. |
| |
The following table shows the
elements you can select for a coincidence constraint. |

- NA: Not Applicable.
- Point: a point, a sphere center, a cone vertex for example.
- Line: a line, a cylinder axis, a cone axis for example.
- Plane: a plane or a planar surface for example.
- Surface: a surface, a tabulated cylinder for example.
- Axis system: only with the same orientation, either both left- handed
or both right-handed.
|
 |
To create a coincidence
constraint between axis systems, they must have the same direction and the
same orientation in the product. |
| |
You can also create coincidence
between an axis system and components of another axis system: |
| |
- Origin point.
- Reference plane, in this case the reference plane must be parallel to
the axis system.
