Selecting objects based on their layer

Mark
I'll assume you have a grounding in programming in a high level OOP language so I'll just put some pseudocode here for you.
Basically your routine could be something like:

a = axlDBGetDesign()
an = a -> nets ;"an" now contains a list of all net objects in the db
foreach net in an
iterate n times, x = nth(n an) -> branches ; and x is now a list of the nets branches
foreach branch in x
iterate n times, y = nth(n x) -> children ; and y is now a liost of that branches children
foreach child in y
iterate n times, z = nth(n y)
if z -> objType == "path"
&& if z -> layer == "ETCH/L02"
then
zs = z -> segments
and then
se = zs -> startEnd

and so on
There are very likely more efficient ways to do the same thing and an experienced Skill programmer would find them. But in a pinch all you need to know is the basic db structure and use some simple loops to match the stuff you want.

Good luck...
