TriadCommandInput not setting initialTransform
Accepted solution
Hi @Joshua.mursic -San.
The fact that addTriadCommandInput cannot be set with any Matrix3D seems like a bug.
However, if I set it in the transform property, I get the result I want when it is displayed.
transformInput = inputs.addTriadCommandInput("constructionTransform",initialMatrix)
transformInput.transform = initialMatrix
During the commandCreated event, transformInput.transform.asArray did not get the correct values.
My guess is that this is because Command.commandInputs is not created until the commandCreated event is completed.
The following sample outputs transformInput.transform.asArray by pressing the OK button.

Yes I think this is a bug, thank you @kandennti
I am trying to create a function to prompt the user to transform a component. They get instances like this where the rotation triad is not aligned well with the part. To rotate the cube around its flat faces instead of the corners it become difficult. I made a button so the user can adjust the triad and align it how they want without rotating the part, but I am having a hard time getting the movement to be correct.
When using the directional arrows the motion is correct, but when using the plane movement is unexpected.

@Joshua.mursic -San.
I found the cause.
The direct cause is this part.

I made the changes to do the processing you want.
