Hello,

I’am requesting your help today for a very ridiculous problem i have : the “is output” option doesn’t work. When i launch my dynamo from Revit, it just executes and doesn’t show any kind of output on the screen. The node i would like to see is just a “watch” node.

Thanks for your help.

Try renaming the watch node.

@martin.honet ,

Are you looking in the dynamo player outputs? That is where theyre typically shown. If you want a UI message to pop up you will need to use python or a custom node such as the simpleusermessage in Rhythm.

@Draxl_Andreas It concerns the “watch” node then i don’t think so.
