How to grab insertion point of mtext?

Posted on 2006-11-28
Last Modified: 2010-05-18
I'm trying to take the following URL and decipher it to allow me to take the following code (listed below) and find the insertion point of mtext so that I can print out the values to a text file alonside of the mtext's values.  Could you please guide me in the correct direction to change the following code to also print out the insertion point of the mtext found?  Thank you for all the help in the past.

Have you tried

strKeyWords = strKeyWords & objEntity.Insertionpoint(0) & vbTab & objEntity.Insertionpoint(1)

instead of

strKeyWords = strKeyWords & objEntity.Start & vbTab & objEntity.End <--- doesn't work

I tried that and I get a Run-time error '451'

Property let procedure not defined and property get procedure did not return an object
with the highlight on that exact line statement.

I think I understand the question but the objentity.start and .end kinda confused me. but I think if you are trying to get the insertion points you have to get it in an array of the 3 points. this is a litttle piece of your code that I looked at and tinkered with:
Sub Mtext_insertion_test()
 Dim objEntity As AcadEntity
 Dim mltext As AcadMText
 Dim mltxt_inspnt(0 To 2) As Variant
For Each objEntity In ThisDrawing.ModelSpace
'    i = i + 1
'    txtStatus = "Found: " & objEntity.ObjectName & " at: " & i & " out of ?"
'    DoEvents
    If TypeOf objEntity Is AcadMText Then
   Set mltext = objEntity
   mltxt_inspnt(0) = mltext.insertionPoint(0)
    'MsgBox mltext.ObjectName
      txtStatus = "Found: " & objEntity.ObjectName & " at: " & i & " out of ?" & " --- found text: " & objEntity.textString
      strkeywords = strkeywords & mltxt_inspnt(0) & vbCrLf
     'strKeyWords = strKeyWords & mltxt_inspnt(0) & vbTab < ---doesn 't work
     'need additional start and end point of object...
 'MsgBox strkeywords
     End If
  Next objEntity

you may not have to dim a seperate variant for the array, it works this way or if you just go straight for the mltext.insertionpoint(0) in the strkeywords line.
this just gets the x coord, maybe that'll help.

yea - norrin radd again to the rescue.

I'm sure glad you have not "retired" fulltime.

I just need some more instruction on how the insertion points work.

When I print out the insertion point of a specific mtext that contains the text: #52.1 for instance and I do a mltext.insertionpoint(0) and it gives me 1316624.97411137 - what exactly does that value mean?

All I know is that where the text was originally inserted into the drawing.
Is this number 1316624.97411137 the number for the X coordinate only since I requested mltext.insertionpoint(0)?
Is the y coordinate available as mltext.insertionpoint(1)?

or the full insertion point is just that 1316624.97411137 only with the 1316624 as the X and the 97411137 as the Y?

yup you got it, y is mltext.insertionpoint(1), z is mltext.insertionpoint(2)
when ever you are after points of any kind 99.999% of the time you are going to have to get it in an array of x,y,z,

"I'm sure glad you have not "retired" fulltime."
nah, slowed down a little but not retired, funny, I almost made a career change recently though, thats kinda scary.

Ps omc was close, but I had to do that acadentity to acadmtext (Set mltext = objEntity) switch-a-roo to get to the insertionpoints, i was going to mention that earlier.....
