ratsnest does not create GND plane

I am currently working on a board right now and I cannot make a GND plane. What am I supposed to do with the gnd terminals of the components of the board

Also, when I try to create a polygon and naming it GND it would still not create a gnd plane because when I click ratsnest it says there are airwires not connected so I connect the airwires using route then after I connected the GND terminals the ratsnest says there is nothing to do. Please help me!

Route the GNDs together, don't let ratsnest do it. (After that you can

use ratsnest)

Name your polygon the same name GND.

In case of multilayer board your GND polygon must be on the same layer

with the other GND connections. Provide a via if necessary.

Possibly use command:SET POLYGON_RATSNEST ON

(or OFF) the same way as written in capital letters.

(I have both commands on keys in the board layout.)

Hi

"Airwires not connected" should not happen. In theory they have to be

connected to a contact at both ends. But over the years people have

found they have scraps of unrouted airwires remaining from

mis-operations they have made.

Question: are you building a board only and did not create the board

from a schematic? i.e. there is no schematic.

I have a netlist from a schematic made from Tango and converted it so that I can run it to Eagle ULP.

Thank you for helping but when I do it the resulting ground plane looks like this. see attached photo pls

Wow this looks weird. I suspect you have stuff at the hidden dimension

layer? You can see the fill trying to keep an extreme distance to some

features. If you try to find the center of those circular shapes, you

should be able to track it down. Show all layers, and you will most

likely see it.

one more thing, that gnd plane appeared only when I checked orphan in polygon properties but if I do not check the orphan the plane won't appear.

For the fast answer to what is occurring

Zip up the board file and attached it.

Sir, I think you made two polygon. Check your design. Do one thing remove polygon and make again and again check ratsnest it should work

After tree years the problem is supposed to be solved
