Extract Joints and Constraints

DVTI_dcsSearchMoveConst Extract Joints and Constraints will extract the Joints and constraints defined in the CAD and apply them as Mechanical Moves in 3DCS

Sub Assembly constraints extraction will automatically create a break Part constraint to make 3DCS Moves work similar to CAD.

 

Searching Filters

Joints and Constraints- Searches for both Joints and Constraints defined in the CAD and extract them as DCS Mechanical moves.

 

Constraints- Searches only for Constraints defined in the CAD and extract them as DCS Mechanical moves.

 

Joints- Searches only for Joints defined in the CAD and extract them as DCS Mechanical moves.

Note:  NX Pattern components are internally linked using Bond Constraint which on extracting constraints will create Fixtogether constraint. This may not be needed by the user which can be deleted later.

If NX Parts are made position override then the constraints from the sub will be extracted to the main assembly to respect the NX method.

Standard Mates from SW to 3DCS Constraints:-

 

1.Lock   - If Lock is created by selecting the assembly and a part then it should be extracted as Fixed    Constraint ( 3DCS)

        - If Lock is created between 2 or more Parts, then it should be extracted as Fix Together( 3DCS)

 

2.   Coincidence - Contact Constraint( 3DCS)

 

3.   Concentric - Coincidence Constraint( 3DCS)

 

4.   Parallel -  Angle Constraint with 0 degree( 3DCS)

 

5.   Perpendicular - Angle with 90 degree( 3DCS)

 

6.   Distance   - Offset Constraint( 3DCS)

 

7.   Angle  - Angle Constraint( 3DCS)

 

8. Tangent - Contact Constraint (3DCS) - When surface contact is needed on 2 cylinders.
