ScheduleSheetInstance bounding box

Hi folks!

I have a little question.

I am trying to place schedules to the view sheet in a vertical chain. The result should be something like:

Actually there are 2 (or more) schedules. I've already achieved what I want. I retrieve bounding box on active viewsheet of each ScheduleSheetInstance and move insertion point for each schedule.

The problem is that ScheduleSheetInstance bounding box is a bit large than actual schedule table:

I've draw borders with this python shell code:

shInst = selection[0] # a ScheduleSheetInstance should be selected to run this code

bb = shInst.get_BoundingBox(doc.ActiveView)

tx = Transaction(doc, "bounds")
tx.Start()

doc.Create.NewDetailCurve(doc.ActiveView, Line.CreateBound(bb.Min, XYZ(bb.Min.X, bb.Max.Y, 0)))
doc.Create.NewDetailCurve(doc.ActiveView, Line.CreateBound(XYZ(bb.Min.X, bb.Max.Y, 0), bb.Max))
doc.Create.NewDetailCurve(doc.ActiveView, Line.CreateBound(bb.Max, XYZ(bb.Max.X, bb.Min.Y, 0)))
doc.Create.NewDetailCurve(doc.ActiveView, Line.CreateBound(XYZ(bb.Max.X, bb.Min.Y, 0), bb.Min))

tx.Commit()

The distance is ~2.12 mm. I hardcoded this value in my code. It seems it works, but I don't know if it works in every possible cases.

So, the question is:

Is there any way to retrieve this value via API?

Thank you!

Cheers, Alexander

Dear Alexander,

Thank you for your query.

How picky you are 🙂

I passed on the question to the development team for you.

I hope this helps.

Best regards,

Jeremy

Thank you, Jeremy!

Sorry, I like good code and don't like magic constants

My pleasure! I like good code too! Just joking ...

Don't worry, I understand you are joking)

Dear Alexander,

Thank you for your patience.

I heard back from the development team.

They absolutely confirm your current approach and provide the magic constant that you were looking for:

For a schedule instance in the sheet view, we add an invisible margin around the actual schedule table.

This margin will show up when selecting the schedule instance.

The margin width is a hardcoded value in the schedule code.

It is 1/12" which is around 2.12 mm.

Right now, there is no way to retrieve this value through API as it is not exposed yet.

I think it is safe to use this hardcoded value as it has been there and remained constant for years.

This is what the schedule instance margin looks like when selecting the schedule instance.

You can see that the move control and the drag height control are showing at the margin bounding box.

I hope this helps.

Best regards,

Jeremy
