In Visual Paradigm, how to have a solid line, rather than a dotted line, towards a class that is created later down the timeline?

Question

I am creating a sequence diagram and I would like the diagram to appear as follows, where the OnlineCart object is placed downwards on the timeline with a solid arrow going towards it:

However, when I try this on visual paradigm, if I use a solid line then the Reservation class appears at the top, and only with a dashed line does it appear where I want it (as shown in the second image). What is the reason for this, and is there any bypass to get a solid line, as that is what is used in my textbook diagrams?

Answer 1

P. 720 of UML 2.5 shows the create message:

As you can see this is a dashed line. Which means your first picture is wrong in this respect and the second one is correct.
