centerpoints

Hello guys,

I am trying to create a program the notifies the user if a circle on one layer shares a centerpoint with a circle on another layer.

Basically, we have a "stud" layer and an "etch" layer. The etch layer tells the laser to etch a reference circle so studs can be welded in the proper spot. What is happening is the etch circle is missing or off center when the drawing is completed. I am trying to find a way to run a program when finalizing the drawing so we know that all studs have the "etch" circles attached. Both circles are brought into the drawing when inserting blocks but when there is customization, things get moved or deleted.

Any advice is greatly appreciated.

easiest might be....

 

erase all etch circles

for each stud circle

    copy @

    change to etch
layer

Next stud circle

 

else you'd have to

    For each stud
circle

        For
each etch circle


size=2>            look
for match

        Next
etch

    Next stud

lots of excess processing there

So, each pair of stud/etch circles are in a block? How is it *one* of these gets moved without the other?

Are the circles all in model space?

are the layer names exactly what you
wrote?

When the block is exploded because some sort of customizing is required, there usually is a lot of stretching and moving.

If the etch circles are to be the same size as the
stud circles this might work

Sub StudEtchCircles()
  Dim oEnt As
AcadEntity
  Dim oCirc As AcadCircle
 
  'DELETE ETCH
CIRCLES
  For Each oEnt In ThisDrawing.ModelSpace
   
If TypeOf oEnt Is AcadCircle Then
      If
UCase(oEnt.Layer) = "ETCH" Then
       
oEnt.Delete
      End If
    End
If
  Next oEnt
 
  'COPY STUD CIRCLES TO
ETCHLAYER
  For Each oEnt In
ThisDrawing.ModelSpace
    If TypeOf oEnt Is AcadCircle
Then
      If UCase(oEnt.Layer) = "STUD"
Then
        Set oCirc =
oEnt.Copy
        oCirc.Layer =
"ETCH"
      End If
    End
If
  Next oEnt
 
 
End Sub

When the blocks are modified or moved. We rarely use the etch layer so sometimes modifications are accidentally done with out the layer being on. Sometimes, the etch is forgotten when making a custom block,

Mark, I think your idea is great. Unfortunately the stud circles have a different size than the etch circle. It doesn't matter what size the stud circle is but all etch circles are to be 1 size. Is there a way I could set all of the circles(now on the etch layer) all to 1 size?

Yes,

read the help on acad circle

they have a radius and diameter
property

set that (whichever one you want to use) in the
code after creating the etch circle

Mark,

Thanks for all of the help. How would I modify the code so I delete every circle on the etch layer but the ones with a diameter of 3? Or just copy only the circles that do not have a diameter of 3? I've tried many different ways but I get errors. I'm not familiar with the typeof methods.

Thanks,

Xi

if Not oCircle.Diameter = 3 then

    oCircle.Delete

...

 

be aware of rounding issues with that kind of thing
(floating point values in any computer system)

 

you can also apply a fuzz factor to get ones that
are virtually =3 but maybe show as 2.9999999999999 etc

 

eg

Function EqualFuzz(a As Double, b As Double, fuzz
As Double) As Boolean
  If Abs(a - b) < fuzz
Then
    EqualFuzz = True
  Else
   
EqualFuzz = False
  End If
End Function

Thanks again Mark.

This is what I have for code:

{code}

Sub cetch()

Dim oEnt As AcadEntity
Dim oCirc As AcadCircle


'DELETE ETCH CIRCLES
For Each oEnt In ThisDrawing.ModelSpace

If TypeOf oEnt Is AcadCircle Then

If UCase(oEnt.Layer) = "ETCH" Then

If Not oCirc.Diameter = 3 Then

oCirc.Delete

End If

End If

End If

Next oEnt

{code}

I keep getting a "Object variable or With block variable not set" error. I'm sure this something I'm doing fundamentally wrong. The closer I look at it the further away from the answer I go.

Do I need to set the diamter?

I forget if you are doing this in dbx or in the
editor?

if in editor you could also use filtered selection
for part of this

what line are you getting the error on, and can you
post so the lines don't all run together?

I am using the editor.

I get the error at "If Not oCirc.Diameter = 3 Then"

If TypeOf oEnt Is AcadCircle Then

If UCase(oEnt.Layer)= "ETCH" Then

oCirc.Delete

End If

Next oEnt



I get the error at line "If Not oCirc.Diameter = 3 Then"

you never cast the oEnt to the oCirc

so either replace oCirc with oEnt or set oCirc =
oEnt when you find it is a circle
