Tpad load problem

[ashofphoenix]

I've got a problem loading an Eagle Tpad layer.

Got an awful red error on python console that is so long I can't really see what the pb really is. I'm not a python and/or FC specialist, but is there a way to obtain a relevant log-file of what is goin' on ?

thx

update : I manage to log something

??? so what :p ^^

I MANAGE TO FIND OUT !
We have some components where only the X/Y position is relevant. These are stickers that are machine - placed . To obtain theirposition, we have made a SMD pad ... of 0mmx0mm So that it doesn't interfear at all with any polygon or ground poly that should be place at this position on our PCB. and I guess a 0mmx0mm SMD pad is not really easy to draw !!! Instead of failing, a warn log and an ignore sequence for that part should have been quite helpful !!!

I solve this creating a special package. However should be nice to have a "quite more verbose debug" from PCB when something goes wrong : parts and or process that was treated when it goes wrong. It's quite a diffcult task to understand which part goes wrong... :/

Thx for reading !
Note : It's note an angry post !!! just the feeling of someone facing a problem without any clues or hints of what went wrong to try to help & solve pb :p

Hi,
no problem :). I will try to add some protection for the pads 0x0 :).

[Mariusz]

Hi,
fixed. Try version from github (PCBobjects.py file).

[ashofphoenix]

Hi !
that works ! Great job ! I wish I could be able to code something like that ^^
Thanks again for all your job

Bump
I talked too quickly ! I tried another board with my "special item" pad0x0 and it doesn't load with github version.
I tried changing the package with a 1x1 and it worked, so i guess it manage to violate your protection ^^

Hi,
can you upload file with problematic models - it will be easier to implement solutions.

[ashofphoenix]

sure ! if you try to change package with the 3D version, it works !

update : well, I think I found something. the 0x0 smd pad has 100% roundness so in eagle.py (line886) , it's addcircle function that seems to be called an not addrectangle (where you put the protection). Maybe protection should be done in eagle.py directly ??? (dunno if that pb occur with other cao)

Hi,
fixed. Try version from github (PCBobjects.py file).

"Image" is on incorrect layer - I changed it to 21.

[ashofphoenix]

Perfect ! Well, the "image" was put on lay25 'coz it was easier to route "without it" on lay21 ;) !

Thx a lot for your help an wonderful job !
