Extracting identities from a dwg file?

[Anonymous]

I would like to know if it is possible to extract the identities of a dwg
with their properties through a vb application. I mean, if I draw in a dwg a
circle and a line, could I read the dwg from a visual basic application and
obtaining the radius of the circle for example?

My knowledges in programming autocad are low and before starting to learn
it, it would be useful for me to see if it is possible to make it

Thanks, regards,

Luisja

You can do what you ask if you have Autocad installed on the machine where you are trying to run vb. VB alone can't interpret the dwg file format.

Here is a very small snippet of code of showing all circle radii. No error
checking. Another way (probably better) is creating a selection set that
filters just circles. The following code just assumes that the drawing has
just circles.

Sub SeeAllCircleRadius()
Dim xCircle As AcadCircle
For Each xCircle In ThisDrawing.ModelSpace
MsgBox xCircle.Radius
Next
End Sub

Hope this helps and Good Luck!

Thanks Ed and Eugene:

now I'll start to read the documentation about VBA.

Greetings,
