Selection.Pickobjects() , should returns selected element in selected sequence

Anonymous — Mon, 06 Nov 2017 11:50:43 GMT

Hi ,

I am facing issue with Revit . I want to get elements id in sequence that I select in case of pick object but pick objects return element is sorted order.

I think after getting element can be sorted but getting selection sequence is not easy one.

Example :

Lets say in Document four element 1, 2, 3, 4.

I select element in sequence like 1, 4, 3, 2.

Currently PickObjects() result= 1,2,3,4

Expected result : 1,4,3,2

Note: I am achieving through adding while loop and using PickObject() . But in this case color of element when selected is not working so user not understand properly. I change color to fix color but some user uses different color scheme. so again this is an issue.

Dear Manish Singh,

Thank you very much for submitting to the Revit Idea Station!

I wish you many votes for this.

Meanwhile, congratulations on implementing a workaround, and good luck finding a way to improve the user feedback for that as well.

Cheers,

Jeremy

This is also causing me an issue, would you be willing to share your code for your workaround? Thanks! I also voted on your idea.

An idea that might mimick the "normal" user experience,

If you change the active selection in the while loop, the selected elements appear selected.

Pseudocode:

while (bool)

{

element = pickobject()

selectedelements.add(element)

uidoc.Selection.SetElementIds(selectedelements)

}

I think it doesn't consider because the option of PickObjects also has window selection.

What order are the birds in the sky when you look out a window, I don't know (I'll sort them by XYZ perhaps).

I was able to do just that, as for the color i haven't figured it out yet.
i'll post the code, hopefully someone will find it usefull

IList<Reference> refrence = new List<Reference>(); try { while (true) refrence.Add(uidoc.Selection.PickObject(ObjectType.Element, "Select lement, esc when finished")); } catch { } List<ElementId> selectionelements = (from Reference r in refrence select r.ElementId).ToList(); using (Transaction tx = new Transaction(doc)) { tx.Start("Transaction Name"); StringBuilder sb = new StringBuilder(); foreach (ElementId eid in selectionelements) { Element e = doc.GetElement(eid); sb.Append("\n" + e.Name); } TaskDialog.Show("title", sb.ToString()); tx.Commit(); }
