Can I draw a reference line in virtuoso?

A couple of approaches. One would be to use dbCreateLine, and then create it on a layer-purpose that is not streamed out. Another one is to use:

dbCreateMarker(geGetEditCellView() "Reference Line" "Experiment" list(0:0 10:4) nil t nil)

and maybe:

pteSetVisible("Markers" t "Objects")

to ensure they're visible by default. You can then see them in the annotation browser too - I just made the message "Reference Line" and the tool "Experiment" - but you can play with that of course.

Regards,

Andrew.

This is really helpful hints. Thank you, Andrew.

And I want furthermore a ruler-like behavor for my action:

When I click one point in the cellview, it can give a line-handler ready to move around, then when I move the mouse and click another point, the handler released and a line is draw between the two points.

Can this be realised in skill script?

How about this?

Example of a enter function to prompt you to enter two points,
and then to create a marker as the result. Might want to use:

pteSetVisible("Markers" t "Objects")

to ensure they are visible.

Call CCFenterRefLine() to prompt the user to create the marker line.
