A question about 'Set Coordinate System' in NI Vision Assitant

Hello,all,

I am a new learner for NI vision.

when I use 'set coordinate system' command in NI Vision Assitant. It works well. e.g.

(The above frame is the example in NI Vision Assitant, please see Help>>Solution Wizard>>Dental Floss Inspection )

However, when I put the program in NI Vision Assitant to create a Labview VI program. (Tools>>Create LabVIEW VI), Then run the VI, it can't work anymore.

The result of Coordinate system out is always like that.

I can't find where the mistake is. I tried some other examples in NI Vision Assitant. If ' set coordinate system' command is used in the program in NI Vision Assitant. and then create the LabVIEW VI.

The problem always occur.

I hope some experienced man in NI Vision could help me.

Thanks.
