Please tell me if this method is right way to create a decal with thermal via on PAD.
My board has 6-MOSFET with similar package with SiR466DP, which is a kind of Power SOP8.
I created decal out of ordinary sop8 adding bottom pad and 12 thermal via.
This decal has 20 pins in stead of 8. See decal.PNG below.
Then create a parts of this by asigning such way that all via has pin number 8 as below.
Now [Check Parts] generate no error and this parts placed on the board without error.
Of course, layout completed and Gerber has been generated.
Now I am wondering if this method is the right way to generate a decal with thermal via on PAD.
Especially, what does it means to assign duplicated name in Parts Information for parts xxxxxxx.
