Element visible in 3d but not 2d

[ivas0016]

I am trying to automate import of security devices into revit. I plan on having one device being manually inserted and then the rest will be automatically placed around that element. Then I have to edit how they appear in graphics 2D. When a new element is inserted using ElementTransformUtilis and then changed using typeChangeTransaction, the code works and you can see the element in 3D, however when I go into 2D its not there. I tried changing a lot of setting in vg, but nothing. Please help!

            // Get the Revit document

                Reference sourceElementRef = uidoc.Selection.PickObject(ObjectType.Element, "Select the element to be copied");
                Element sourceElement = doc.GetElement(sourceElementRef);

You probably need to adapt your view settings appropriately. I suggest you do so manually in the end user interface first, to ensure that you have understood the principles and that it works correctly for your specific devices. Once you have it working in the UI, the API aspect will be easier to handle.

It was the view range 🙂
