Direct linetype

[kusaleev]

Hi!

Currently, 2 types of relationships are supported (skinparam linetype):

• Standard (when elements are loosely connected and arrows (skinparam linetype disabled))
  -ortho (when the bend angles of the arrows are at right angles (skinparam linetype ortho))

Is it possible to establish a “direct” connection style when each element is connected and the arrows do not bend?

Hi,
Other than actually using skinparam linetype ortho or skinparam linetype polyline, the best way I can think of is adding hidden relationships using the Lay_U, Lay_D, etc. helpers and trying to convince graphviz to draw it a certain way. (depends a lot on the complexity of the diagram though)

So instead of:

@startuml
!includeurl https://raw.githubusercontent.com/RicardoNiepel/C4-PlantUML/release/1-0/C4_Container.puml

Person(customer, "Personal Banking Customer", "A customer of the bank, with personal bank accounts.")
System(banking_system, "Internet Banking System", "Allows customers to view information about their bank accounts, and make payments.")
System_Ext(mail_system, "E-mail system", "The internal Microsoft Exchange e-mail system.")

Rel(customer, banking_system, "Uses")
Rel(banking_system, mail_system, "Sends e-mail using")

Rel(customer, mail_system, "Sends e-mails to")
@enduml

rendering like this

you could try to force drawing the entities in a rectangle shape like

@startuml
!includeurl https://raw.githubusercontent.com/RicardoNiepel/C4-PlantUML/release/1-0/C4_Container.puml

skinparam linetype polyline

Person(customer, "Personal Banking Customer", "A customer of the bank, with personal bank accounts.")
System(banking_system, "Internet Banking System", "Allows customers to view information about their bank accounts, and make payments.")
System_Ext(mail_system, "E-mail system", "The internal Microsoft Exchange e-mail system.")

Rel(customer, banking_system, "Uses")
Rel(banking_system, mail_system, "Sends e-mail using")
Rel(customer, mail_system, "Sends e-mails to")

Lay_R(customer, mail_system)
@enduml

It's more of a PlantUML issue though.

@adrianvlupu

Thank you for your answer!

I know this hack from C4 styles:)
I hoped, than something else can resolve my problem with lines direction.
Okay, I will playing with layout and relations on my scheme.
