Decal Replacement

jzsori Apr 5, 2011 7:11 AM

Is there a way to batch replace a bunch of footprints AND maintain the same orientation? I'm working on a job where the client wants me to replace my CAPC1005N footprint with his 0402 footprint. The problem is that the created orientations of the two parts are different. This would require me going thru hundreds of parts and rotating them back to how they are currently placed in the design. Checking the keep attributes box doesn't seem to do it. TIA for any suggestions.

Create a new decal to match CAPC1005N orientation and save it as 0402_ALT.
You will not have to deal with parts rotation.

I think the easiest thing would be to edit the customer 0402 decal and change it's orientation to match your IPC CAPC1005N.

My issue is that, at the end, everything needs to be 0402. With any renaming/re-orienting I end up with one or the other getting rotated because ECO uses the design footprint and I cannot force it to use the library footprint.

Denis - as with my reply to varora - as soon as I change the orientation of the client 0402 then the ECO process will make the CAPC1005N replacements ok but will rotate the existing 0402 placements.

You can easily rotate the updated parts back to their original position after the replacement with the new decals. It will take less than one minute. Since the difference in rotation between all of the old decals and new decals is the same, you can do all of them at once.

Use the Find dialog box to select the new decal by name.

Rotate into the original position using CTRL-R. Depending on the rotational difference, you'll need to press CTRL-R 1-3 times.

This works because of the way PADS treats traces attached to pads, as it only moves the segment from the closest vertex. All of the routing will snap back into place of the original design after the rotation.

Were it that simple :~)) No consistent use of pins 1 and 2 AND the padstacks between the new and the old are different. Different pad sizes and different spacings so I was getting a lot of no connect diamonds that I had to reroute. Pretty much all done now but I appreciate everyone's input.

It is that simple. I correctly answered the question you asked. Your problems lie in your communication skills, both in how you framed your question here in light of the new information you just added, and how you deal with your client about changes. That type of disconnect should never have happened.

Well, somebody turned nasty. Haven't seen that since the rants on the listserver. Totally uncalled for in my opinion.

I stand by my statement. I guess you need to learn to take criticism better too.
