How to use TriadEvents?

[liminma8458]

Hi, everyone,

TriadEvent has a very good dialog interface to move or rotate an item, as below picture 1. But I can't find a sample code on how to do it anywhere (in help file, there is one that only is able to move the triad itself). So if I have an assembly with a single block inside and want to enter in the dialog boxes x: 10, y: 10, z: 10 to move it, how should I setup the triadevents to do it? Another scenario is if I drag the triad to new location, how to make the block follow to that location?

(Attached is the assembly models and my preliminary code which only is able to move the triad itself.)

It depends how you would like to show the transformation of the occurrence in assembly, you can check the CoordinateSystem in OnStartMove, OnMove and OnEndMove to calculate the transformation of each move and then tranform the occurrence for each move. Silimar you can use the OnStartSequence and OnEndSequence to calculate the transformation of a series of move and tranform the occurrence once for these moves. 

A simple case is you place an occurrence to the origin of assembly and no rotation, and you place your triade to the same coordinate of your assembly, then in each OnMove event you can just set ComponentOccurrence.Transformation = CoordinateSystem to tranform(translate/rotate) the occurrence. For other cases you usually need to calculate your matrix for occurrence's transformation.
