Hello
I made a mechanism with the CATIA Assembly module. The kinematic connections used (slides, pivots) are made thanks to assembly constraints.
For example :
For a pivot :
1 right/right coincidence stress (for the direction of the pivot)
1 plane/plane coincidence stress (with two planes perpendicular to the pivot axis)
and an angle constraint for the control of the link
For a slide :
1 axis/axis coincidence stress (in the axis of the slide)
1 plane/plane coincidence stress (with two planes containing the axis of the slide)
And a shift constraint (distance constraint) for the control of the link.
By playing with the " measure " checkmark of angle and offset constraints, I can set at the assembly the steering coordinates of the links (" not in measure ") of the dependent coordinates of the links (" in measure ").
I am now trying to go to the DMU Kinematics workshop before I can animate my mechanism. To do this, I use the " assembly constraint conversion" tool. With the help of this tool, stress recognition works well and I get the desired connections for my mechanism. On the other hand, the angle and offset constraints that allowed me to enter the values of the coordinates are not used in DMU. I think that the driving coordinates are handled by the " commands " and the dependent coordinates should be automatically determined by CATIA (solving the positional and angular constraints associated with internally resolved kinematic loops).
Questions :
Can angle/offset constraints (created with assembly) cause conflicts with Kinematics DMU commands ?
Thank you in advance for your help
