Obtaining the start & end point of a structural framing member

[Dave F.]

Hi
I'm using RST '09.
I'm about to start learning to program in Revit (I'm conversent with VBA within AutoCAD).
I was talking to a colleague of mine, hoping to glean some tips 'n' tricks from him.

He stated that the start/end point of a structural framing element or the insertion point of a pile foundation family couldn't be obtained as it wasn't exposed by the API. He said that they could only be obtained by using a 'node' family/routine that he'd developed had to be placed at the required points & then using his routine put the X,Y & Z into parameters within that family.

Is he correct? I'd be surprised if this info isn't avialable. I think it would limit the usability severely.

Are you aware of an online example i could have a look at?

Regards
Dave F.

All Elements in Revit have a Location Property - look it up in the help file. As it says this is either a point or a line or curve depending on the type of element. There should be some samples with the SDK that show how to use this.

The location of the analysis wire is also available for structural framing in Revit Structure. Look at FamilyInstance.AnalyticalModel Property in the help file
