Edit section view cut line

[kirill78zah]

Hello.

In Revit I can manually change length of section view cut line dragging by its grips.

Below are two pictures illustrating such manipulation.

Is it possible to do it programmatically?

Hi!

Yes, you can do it. Look at this topic: https://forums.autodesk.com/t5/revit-api-forum/center-of-a-section-view/m-p/7878460#M29735

In my comment there is a code, that should be executed directly from section view. If your active view is not document active view you should retrieve your view section first.

Thanks, Alexander.

Later I will test  this code you posted.

But can you clarify: is this code changes CropBox of ViewSection and it causes changing cut lines in other views?

if I understand correctly, when I drag grips of cut line manually it doesnt changes CropBox.

I mean there are two kind of grips in cut line:

 - triangular to change CropBox;

 - circular to change length of cut line in active view.

Look at the picture below:

I need to change only length of cut line.

Yep, when it is changed manually it changes the Origin of view section. In the API this does not work (there is no setter of Origin property)

The code changes crop box (as triangular grips do). To change the "length" just set VIEWER_BOUND_OFFSET_FAR parameter value
