The Z Position (height), of a dynamic component, is entered into the dynamic “Component Options” by of a table.

The X Position of the dynamic component is determined using the “CURRENT(“Z”)” function in the attributes.

Because of the order in which the coordinates are determined in the attributes, X - Y then Z, the Z coordinate doesn’t return the current position that has been entered, it returns the Z position previously entered.

# Predetermined proceedure order makes for dynamic component failure

This Model demonstrates the issue.

This is important because I am attempting to repair issues with my Dynamic stair case that is now broken.

With the help Pythagoreas and Tom Kluyskens from Trimble.

Oddly enough applying the math, where a=Z; b=X and c=Y axes, and the height Z and length Y are known.

Using x=sqrt((y*y)-(z*z)), the point does not end up in the projected spot in the rail where it should.

I must have the angle (rotation) slightly off on the rail, see the uploaded portion of the model.

Well I will have to see if I can’t increase the accuracy of the rotation.
