It works. Try drawing a horizontal or vertical wire/net, copy it and paste

as an extension to the first, either continuing one end or overlapping. Now

optimize it and it will become one wire instead of two.

The two wires also need the same angle and a ommon point. That will be

difficult to obtain on tilted wires.

The reason it may not seem to work is that there is a setting in the

Options to always use optimize.  So when you draw a net in two segments it

will auto-optimize it.  So there is no need in that case for optimize.

Turn that setting off and then you'll notice it.  I did that once by

mistake and it I noticed right away.

and then I tried over and again to join two wire segments on a PCB.

 

Nothing happened.  I am left with an airwire.

 

Is there some special case or circumstance besides requiring the lines

being the same width and in the same layer? I can't do anything with it.

Very frustrating.

 

Any ideas what I might be doing wrong? Does Optimize work for other users,

or is that little icon sitting on my Eagle PCB console a Cadsoft prank?

Naah that couldn't be, and yet...

 

Thanks for any advise.

Thanks Morten and James. The "Help" text does not state that, as a

prerequisite the target wire segments must be contiguous as in overlapping,

but I suppose it should be "understood".

Actually, yesterday was the ONLY time I tried to "optimize" non-contiguous

segments; expecting an air-wire to get routed... which does not make much

sense now that I think about it. (That is what ROUTE is for.)

Naturally I feel somewhat stupid because all of a sudden it seems to work OK

on contiguous wire segments. HOWEVER I don't remember having any luck with

it before but I don't even remember the last time I tried. It was many moons

ago.

I tested Altium and Protel and one of my biggest beefs with those products

was that while making library components I would very often wind up with

lines that were made up of many individual segments. It was very hard to

move things without having them break apart. Maybe there was an similiar

command available in those products, I don't know. Don't care.

I'll play around with Optimize some more and try to figure out what I was

doing wrong.

Thanks again.
