List all view scale on current sheet

Hi guys..

I would to make a list of all view on the current sheet and find relative view scale.

csheet = doc.ActiveView For Each vw As Viewport In csheet.view Next

I thinking to use this..but csheet.view is not correct..

Where I can find a sample? What approch I have to follow?

thanks

Stefano

First cast your active view to a ViewSheet using :

var sheet = doc.ActiveView as ViewSheet

then use sheet.GetAllPlacedViews() to find the views placed on your sheet.

sorry..but I have problem with the view.scale

in the for each I can't utilize viwp.scale because scale is not a member of viwp

Dim CTAV As ViewSheet = doc.ActiveView Dim LIST As IList(Of Viewport) = CTAV.GetAllPlacedViews() For Each viwp As Viewport In LIST Next

I work in C# - I think this is it:

For Each viwp As Viewport In LIST Dim view as View = doc.GetElement(viwp.OwnerViewId) Dim sc as Double = view.Scale ... Next

Hi @stefano.cartaKGT96 ,

GetAllPlacedViews returns a list (Iset) of Elementid's not Viewport elements

See fragment below, this retrieves all unique scales.

If TypeOf (doc.ActiveView) Is ViewSheet Then Dim VS As ViewSheet = CType(doc.ActiveView, ViewSheet) Dim ViewScales As New List(Of Integer) For Each ViewId As ElementId In VS.GetAllPlacedViews Dim ViewElem As View = CType(doc.GetElement(ViewId), View) Dim Scale As Integer = ViewElem.Scale If Not (ViewScales.Contains(Scale)) Then ViewScales.Add(Scale) Next 'ViewScales.Distinct 'Or use distinct after all scales are added. End If
