Sending regions to another array

[Anonymous]

I have an array of regions declaired as
regionObj as variant

Now there are 20 regions in there. I would like to send even items (i.e. 2,4,6,...20) to another 2 dimentional array.
arrayList (1 to 10, 1 to 3) as variant

but it gives me type mismatch error.
I have also tried to claim it as acadRegion, but it didn't work either. Does anyone know what is the problem?

it doesn't give an error at my computer, can you show a little bit more from
your code?

Humm, it doesn't?
Well, here is what I tried. U need to make an array of circles called curves here....


'make regions out of circles in curves
Dim regionObj As Variant
regionObj = ThisDrawing.ModelSpace.AddRegion(curves)


'make rings out of regions- subtracting them 2 by 2
For n = 2 To 20 Step 2

'subtraction
regionObj(n).Boolean acSubtraction, regionObj(n + 1)

Next n

'here I want to send them to another array, cuz I need to
'fill the other columns with other information about
'the rings

Dim arrayObj(1 To 2, 1 To 10) As Variant
arrayObj(1,1) = regionObj(2)

'but it gives error!
'"object doesn't support this property or method"

you missed "SET" to store a reference to an object:

set arrayObj(1,1) = regionObj(2)

Oh Thanx! Well, I am not really a programmer, so.... 🙂

Hey, can I ask you something else?
What I actually wanted to do is to get 10 items (circle regions) out of an array of 20, and make 10 copies of them. So that at the end I would have 100.
I guess the idea of assigning those 10 to another array and copying the array was wrong. Cuz by copying an array I am not actually COPYing geometric entities, I just assign them to another array.
So the other thing I thought of was to make a selection set and sent those 10 there, then I make 10 copies of it. Is this the way to do it?
Also if that is the way, would the Xdata be copied along with the objects?

if i understand your question correct, then you have to copy the geometry and
get the copy back to your memory-array, if so you can create your copy with the
copy-method:

dim tNewEnt as acadentity
set tNewEnt = tBaseEnt.Copy() 'where tBaseEnt is one of your existing entities


is that what you missed? - alfred -

Well, my question was more of how I can copy all the objects in the array at once.
I know that I can do that with "CopyObjects" which takes arrayas as argument:

copyArray = ThisDrawing.CopyObjects(oldArray)

But it gives me an error in the following senario....
I have an array of 20 circles in "oldArray"
I copy the ones with odd index (1,3,5,...19) to another array of 10 circles (newArray).

for n=1 to 19 step 2
set newArray((n+1)/2)=oldArray(n)
nextn

Then I try to copy the "newArray" with the same command (copyObjects)but it gives me an arror ("Array is not valid")

Funny thing is that it doesn't give me any error if I try to copy the "oldArray". It's just with the "newArray" that I have problem.
U know why this happens?

i havn't tried it, but could it be that your array has an empty element
newArray(0)? is your option base set to 0 or to 1?
