[ORCAD] Design Outline vs Outline

(1/2) > >>

Pack34:
I've received warnings when using the films and views from older projects about using DESIGN_OUTLINE and CUTOUT instead of OUTLINE. I made the changes to get rid of the warnings, but does anyone know why this is a thing? Is this just to be certain that internal cutouts are always properly generated since the one class is split into two?

Uky:
I do not know why Cadence made the choice to change it and I have seen this too.
The thing to watch up for is that - if I remember correctly - it is not possible to change graphic elements
subclass from one to another since one is a shape and the other should be "line(s)" but there are more
or less cumbersome ways to do this.

Anyway, generating gerbers from a design with warnings should always IMO be followed by a free (non-Cadence) viewer
to verify the results after generation.

I noticed that, ended up redrawing the outlines.

I always double check with GerbV but probably need to switch. For some reason it's incredibly slow when trying to read files over a network. What do you use?

Uky:
I use Pentalogix "ViewMate"

AndyC_772:
I use gerbv and have never had any issue with using it to view files over a network. Are any other network operations unusually slow too?

I recently replaced my old Qnap NAS with a new model because it was weirdly slow with anything that involved a lot of file accesses. Raw data throughput with big files was fine, but the number of discrete operations/sec was severely limited.

The latest versions of OrCad PCB were particularly badly affected. They'd load and save .brd files quickly enough, but trying to open a folder containing a large number of files (eg. my symbol library) could easily take a minute or so, populating the file browser a few file names at a time.
