Rotation of connectors

[DagBruck]

Proposal: introduce a rotation attribute for connector geometry, cf component geometry. The angle is specified counter-clockwise in degrees. Examples:

<ssd:ElementGeometry x1="20" x2="40" y1="-32" y2="-12" rotation="180" />
<ssd:ConnectorGeometry x="0.5" y="0" rotation="-90" />

The motivation is

• Rotation makes sense as soon as we deviate from the most basic layout of components.
• It cannot easily be compensated for by "smart" automatic layout.
• It is needed to map e.g. Modelica models to SSP without loss of layout information.
• It is already supported by e.g. Dymola.

The counter argument is

• Connectors can be automatically rotated based on kind and position on the component with reasonable results.

Estimated complexity

• Low.

Thanks @DagBruck for creating this issue.

Element rotation is already supported.

The counter argument is

I agree with your counter argument.

That obviously works for this simple kind of component:

But what do we do with

And then there is the problem with acausal connectors. We cannot assume there is an "in" or "out" direction . Not to mention an abomination like this.

Element rotation is already supported.

I have updated the issue to make that clear.
