So, thanks very much for helping with the rounded corners on behavioural vs. structural elements - but for Motivation elements, the 'chopped-off' corners are used to separate them (see below - click through for reference).
Is there a way to recreate this look, similar to the skinparam for rounded corners, perhaps 'chamfercorner'?
Example:
@startuml
skinparam archimate {
shadowing false
}
skinparam archimate<<strategy-capability>> {
roundcorner 25
}
skinparam archimate<<assessment>> {
chamfercorner 25
}
archimate #STRATEGY "Resource" as SResource <<strategy-resource>>
archimate #STRATEGY "Capability" as SCapability <<strategy-capability>>
archimate #STRATEGY "Course Of Action" as SCourseAction <<strategy-course-of-action>>
archimate #MOTIVATION "Assessment" as MAsssessment <<assessment>>
