Re: [PROTEL EDA USERS]: No Net assignments on tracks & vias...

["David Cary" <dcary@Brunswickoutdoor.com>]

Dear Brian Guralnick,

When I'm placing a track
  P T click, click, click, click
where each click of the mouse drops a new segment of track.
I *can* start routing from a via or track or existing item to a "No Net" via or
track by getting close and momentarily turning off "Avoid Obstacle"
  click, click, shift+R shift+R click, click, shift+R click, click, click ...
click Esc Esc.
(It takes at least 2 clicks to place a segment "into" and then "out of" the "No
Net" via).
Note that I do *not* have to escape out of place-track mode to switch to "Ignore
Obstacle" and re-start.

While placing track, the shift+R cycles through "Avoid Obstacle" (my favorite
default), "Push Obstacle", and "Ignore Obstacle" (current mode displayed in the
status bar). You might find "Push Obstacle" helpful in tightening up busses.

Later I do a "Design | Netlist Manager | Menu | Update Free Primitives From
Component Pads" which changes the net of those "No Net" pads and traces to the
net to which I just connected them, to make DRC happy. That update seems very
slow. Your suggested user interface would be much better.

    That's it, now I'm really annoyed.

    How come in Protel99SE PCB, vias & tracks who's nets are 'No Net' do NOT
automatically change their net names to which ever other net'd items I
connect them to?

    Example:  If I create a grid of vias or tracks, or multiple conected
items which end up with the default 'No Net', why am I unable to just start
routing from the via, or the track, or an existing item with a real net, and
just join the 2?  The manual router should never consider 'No Net' items as
obstacles with regard to any real net'd item.  When a 'No Net' item is
joined to an actual net'd item, the router should change all the physically
connected 'No Net' items to the new actual net.

    Have I missed an option or setting within Protel?

Completely frustraited out of my mind,
    Brian Guralnick.
