Coincidence

The DVTI_CoincidenceConstraintCoincidence Constraint locates the features to be coplanar, coaxial or coincident.

Feature Specification

Object and target features can be any of the following combinations.

 

Object Features                                        Target Features

One spherical feature or                                        One spherical feature or

One point to define a center or                                One point to define a center or

One feature to define an axis or                                One feature to define an axis or

One pair of points to define an axis or                        One pair of points to define an axis or

One feature to define a plane or                                One feature to define a plane or

Two features to define a slot/tab centerplane or                Two features to define a slot/tab centerplane or

One point to define a plane                                One point to define a plane

 

One common use of the Coincidence move is to hold a point on a plane.  This can be done by selecting a point as one feature and a planar feature mesh as the other.

 

Procedure

The coincidence constraint can be created for a variety of model applications, but the basic procedure is as follows.

 

STEP 1        Feature Tab:

Click in the Object Features box and select one or two features from the part(s) to be moved.

Click in the Target Features box and select one or two corresponding feature(s) of the target part(s).

 

An example is shown below where the axes of the cylinders are the Features.

STEP 2        Move Parts Tab:

Parts should automatically be added to Move Parts based on the Tree structure of the model.  Verify that these are the desired parts.  Only two parts can be added to this list.  The first part corresponds to the Object features and the second part corresponds to the Target features.

 

STEP 3        Settings Tab:

If points have been selected in the feature lists, be sure to check the desired Use Point As setting.

Update other settings as desired.

 

STEP 4        Floating Tab:

Turn float on/off by checking the box after selecting the hole-pin pair from the drop-down list (if applicable).
