vertically aligned columns of boxes in class diagram?

Question

Assuming this plantuml file:

@startuml
top to bottom direction
class Loooooooooooooooooooooong1
class Loooooooooooooooooooooong2
class Short1
class Short2

Loooooooooooooooooooooong1 -r- Loooooooooooooooooooooong2
Short1 -r- Short2
Loooooooooooooooooooooong1 -d- Short1
Loooooooooooooooooooooong2 -d- Short2
@enduml

I want to have 2 columns of vertically aligned boxes with properly straight edges.

See the diagrams here: https://imgur.com/a/m0iQ1wx

What am I missing?

Thanks!

(It's very unfortunate that I can't add the PNGs to my post -- I'm hitting a 8000 character limit.)

Answer 1

You can add the green parameter:

@startuml
skinparam linetype ortho
top to bottom direction
class Loooooooooooooooooooooong1
class Loooooooooooooooooooooong2
class Short1
class Short2

Loooooooooooooooooooooong1 -r- Loooooooooooooooooooooong2
Short1 -r- Short2
Loooooooooooooooooooooong1 -d- Short1
Loooooooooooooooooooooong2 -d- Short2
@enduml

Here what you'll get

Minor refinement to get closer to OP ideal, using 'norank' between Short1 and Short2.  This actually eliminates the need for the ortho linetype.
