Help - objects disappearing

[Anonymous]

I have the following bit of code which changes the layer of an object. It works fine. However, after changing the layer I erroneously made the object invisible. I should have turned the layer off instead (but I don't know the code for that yet.)

Sub SelectOnScreen()
' This example adds objects to a selection set by prompting the user
' to select ones to add.

' Create the selection set
'On Error Resume Next
Dim ssetObj As AcadSelectionSet
Dim GridSelectionSet As AcadSelectionSet
Set ssetObj = ThisDrawing.SelectionSets.Add("GridSelectionSet")

' Add objects to a selection set by prompting user to select on the screen
ssetObj.SelectOnScreen


Dim objCount As Integer
Dim I As Integer
Dim PickedObj As AcadEntity

objCount = ssetObj.Count
For I = 0 To 19
Set PickedObj = ssetObj.Item(I)
PickedObj.Layer = ("Grid " & Right(Str(I + 210), 3))
PickedObj.Update
PickedObj.Visible = False
Next I
ssetObj.Clear
ssetObj.Delete

End Sub

The problem is is that I didn't notice what was going on until I was almost done with the project and I had already done a number of saves. Now I can't find the objects anywhere.

Are they still on the drawing somewhere? I made sure all layers are turned on and I've done Ctrl-A to select all but they seem to be gone. I'd hate to have to re-create a couple hundred objects all over again.

objCount = ssetObj.Count
For I = 0 To 19 <==You may want to replace "19" with "objCount-1"
Set PickedObj = ssetObj.Item(I)
PickedObj.Layer = ("Grid " & Right(Str(I + 210), 3))
PickedObj.Update
PickedObj.Visible = False <=== Does this "Visible=False" prompt
you something?
Next I

Yes, that's the line I used by mistake. If I knew the code to turn off the layer of the object I just modified I should have used that instead. But I don't know the code to do that.

But now that PickedObj.Visible = False has been used I don't seem to be able to go back from it. The objects made invisible are nowhere I can find. And as I mentioned I saved a few times before I noticed something was wrong.

So I guess I need 2 things: the code to turned off the modified object layers and how to find my invisible objects. Thanks.

You can simply run a quick code to turn all entities' Visible to True
(assume the invisible entity is in ModelSpace):

Create a public SUB in a module as macro:

Public Sub ShowAllEnt()

Dim ent as AcadEntity
For Each ent in ThisDrawing.ModelSpace
ent.Visible=True
Next

End Sub

Then run the macro.

Ah great! That worked. Thanks so much. I love doing code but it does make things so much easier and faster when I know what I'm allowed to write. The Help files are ok but sometimes you need a help file just to use the help file. 😉
