I am having a question about the following diagram - is this expected that the directions left/right/up/down are not working here?

rectangle Export {
rectangle PDF {
rectangle HTML {
rectangle ePub {
rectangle Word {
Export -left-> PDF
Export -right-> HTML
Export -down-> ePub
Export -up-> Word

Hello A.,

If the component or rectangle is empty, it is not necessary to have curly brackets:

rectangle Export {

You can suppress them with:

rectangle Export

Then, we obtain the good behavior:

It seems that curly brackets must be use normaly if there are sub-elements [package or group], see also on the doc.:

If that can help,
