Guidelines to create Opening Lines in 3D for doors/windows?

[Durval]

Hello,
My searches on this topic were not successful.
Does someone have any tip on how to create 3d opening lines that show in sections/elevations and schedules for my custom doors and windows?
Is it just a matter of adding LIN_ commands to the 3d script?
What global variable (if any) should I use to make these LIN_s only visible when "Show Opening Lines in 3D Projections" are selected in Model View Options?
Thanks in advance.

Yes, if all you want is a solid line. No, if you want a dashed line. The LIN_ command only creates a solid line. for a dashed line the routine is more complex, creating the appearance of a dashed line with a series of spaced solid lines. You can take a look at how the standard ArchiCAD windows and doors do this, and possible just copy the subroutine into your doors and windows.

There is not a Global Variable, the MVO is using the parameter name to communicate with the library parts, (look at the Master Scripts of the ArchiCAD library parts for the command LibraryGlobal), so if you use the same parameter name as the ArchiCAD library you will be able to use the existing MVO without creating you own LibraryGlobal.

In both cases looking at the ArchiCAD library parts to see how they work should help.

Thank you very much David for the tips. They were very helpful.
I will explore the ArchiCAD objects as you suggested (but only when I'm not in such a tight deadline to deliver my window schedule!).

Good idea GDL can be a rabbit hole.

You always think you will solve things in less time that it is actually needed, but you keep going, telling to yourself "if I make a good tool, I'll save a lot of time in future"

Is this the sort of thing I need to understand if I am creating custom door PANELS and want to show the opening lines too?

No. The other door options (frame, opening lines, etc.) will still be available, you are just adding a custom leaf to the door part.

The opening lines do not seem to be coming thru when I am using a custom panel. I checked my global settings as well as the object's opening line settings.

rgarand:

Works here. A few things to try:
1. Do the opening lines appear if you change to one of the standard door panels and leave all the other parameters as is?
2. Try viewing the door in 3D, Wireframe Mode, and see if the lines appear, maybe they are inside the door panel.
