powercopy and relation to input element (not def element)

[itsmyjob]

I create a line and a point on curve (middle), then I define a formula between the point activity and the line activity so they are sync. if I deactivate the line, the point is also deactivated, no error message.

no a create a powercopy of that middle point, i also make sure the formula is in the definition of the powercopy.

but when i instantiate to a new line, my new point activity is linked with the first line activity (the one used to define the pc), i want it to be link with the input line of the pc.

I am working in R20.

Thanks for your help

Eric,

I'm on R20 also, and it worked OK for me.

I made my original point as a POINT ON CURVE and selected the MIDDLE POINT option (Ratio = .5). I don't see a formula in the tree. When I instantiated the PowerCopy, my new points have the .5 ratio along the selected input line.

I didn't follow the deactivation steps - were you just verifying the parent/child relationship?

well, i am looking for that parent children deactivation relation more than the mid point itself

Eric,

While looking for a way to get it work, i've found that the only types of input possible for power copy in terms of parameters are user parameters.

in order to get the link follow the powercopy we have to create a boolean parameter. Link the value of the parameter to the activity of the feature and use it as an input for the power copy. Therefore, you can create links between power copy's elements. if you have to link the activity of the elements created by the powercopy to activate/desactivate other features make sure to create a new boolean parameter while instanciating the powercopy.

no need to call me telling me you've got an answer
The next step would be to rename new instances of parameters as "user base name" + instance number in order to keep trace of parameters for further reordering in the parameters' tree
