Latest Ruler in a layout window

JackPro

Hi Andrew,

I have skill code requirement like this:

I will draw many rulers in the layout window. Is there any way to find the latest ruler which exist on the layout window?

If the ruler is a save-able object, we can undo them in a order they are drawn. But I am not able to get latest ruler in skill code.

Regards,

Venkatraman

    If you have code that creates the rulers, then you could create a group (dbCreateGroup) which is ordered and add each new ruler to that group. Then you'd know.

    Other than that, you can empirically find that the last ruler seems to be:

    car(last(setof(marker cv~>markers marker~>objType=="ruler")))

    However, I don't think there's any guarantee that the rulers will be returned in a particular order. It seems to be that the last in the list is the latest added, but since this is not documented, it could well change due to implementation optimisation at some point. So proceed with care...

    Regards,

    Andrew
