Select chain of lines by pressing tab key

[Anonymous]

In Revit if I want to select a chain of lines or walls or ducts for example, I can hover my mouse on top of one of those line segments and press tab. Revit will find the interconnected lines and highlight them, then I can click to select them.

I am trying to have Rrevit do this on an API command. How do I tell Revit to select all the lines in a chain by pressing the tab key so that I can get the chain of lines?

Thank you.

I am not aware of any Revit API support for this functionality.

Jeremy,

Thanks for the prompt reply. I found the CurveLoop class but I don't really understand if it relates to what I am asking.

thanks again.

Dear Redskyrc,

No, probably not.

A curve loop is used to describe a closed profile.

The string of connected lines that you describe does not fall into this category.

Best regards,

Dear redskyrc,

you will have to do the calculation by yourself.

Just get neighbouring curves by comparing their end points with your given curve's ones.

You will find a similar approach in the "Touching Beams" sample:

Also, you could have a look at the TraverseSystem sample in the SDK.

The point is to traverse the system/beams/lines recursively.
