Methods of Viewing Nets

Hi

To do away with sticking tape on your monitor.

Create a user defined layer and place construction lines in that layer

to guide your placement of polygon outlines. You will still have the

issue with disappearing shown items though as you create the

construction lines.

I'm not quite sure how that fixes anything. The OP's problem is that,

while he can highlight the net he's interested in, the moment he starts

to trace around it the highlighting disappears. Use of any tool switches

off the "show". So he can't trace it.

One thought that occurred to me just now - do a "show" to get the

highlight, then use a screen capture tool to capture an image. Place

this on an image viewer alongside the Eagle window as a guide. You

should be able to draw the polygon outline by reference to the patterns

of pads and vias around the highlight on the image.

But I'd still definitely vote for a "persistent" option to make the

highlight remain until the next use of SHOW (or possibly some few other

tools like RATSNEST)
