It is impossible to create point curve, roll curve, slide curve, point surface jointd, if the parts involved in the joint creation are not well positioned.

This section provides two examples and a tips summary table showing you how to quickly solve this problem:

Scenario 1: Creating a roll curve jointTop

  1. Select the Roll Curve Joint icon in the Kinematics Joints toolbar.
    The Joint creation: Roll curve dialog box is displayed

  2. You cannot select the Curve 2 in the geometry area. It is impossible to create the roll curve joint because the parts are not well positioned:

  3. Click Cancel to exit the Joint creation functionality.

  4. Select Digital Mockup > DMU Navigator from the Start menu.

  5. Reposition the parts using the Snap capability. This is what you obtain:

  6. Select the Roll Curve Joint icon again in the Kinematics Joints toolbar.
    The Joint creation: Roll curve dialog box is displayed. You can now create the roll curve joint: the parts are correctly positioned.

  7. Click Ok to end the joint creation

 

Scenario 2: Creating a point surface jointTop

  1. Select the Point Surface joint icon in the Kinematics Joints toolbar.
    The Joint creation: Point Surface dialog box is displayed:

  2. You cannot select Point 1 in the geometry area. It is impossible to create the point surface joint because the parts are not well positioned:

  3. Click Cancel to exit the Joint creation command

  4. Select Digital Mockup > DMU Navigator from the Start menu

  5. Reposition the parts using the Snap icon. This is what you obtain:

  6. Select the Point Surface Joint icon in the Kinematics Joints toolbar.
    The Joint creation: Point surface dialog box is displayed.This time you can create the point surface joint because the parts are correctly positioned.

  7. Click OK to end the joint creation.
 

Tips: summary tableTop

The following table aims at giving you tips for creating point and/or curve joints.

Joint  types
Creation Conditions
Tips:
for positioning parts
in specific context
Point surface

Point curve

 The point must be located on the curve.    in ENOVIA: If the parts involved in the joint are not well positioned, create the mechanism on positioned assemblies.
Roll curve

Slide curve

 The two curves must be coincident and tangent in one point.  Roll Curve joint
  • create a point and a line tangent to the curve on this point for each part.
  • In the Assembly Design Workbench, snap the two points and the two lines.
