If I build a part using the Calculator with the following settings applied, the silkscreen and assembly drawing are rendered as expected but the 3D-model still includes the pin 1 dot. Do I need to make the 3D model separately using FP Designer in order to remove the dot or is there another option I'm missing somewhere for accomplishing this using the calculator?
Thanks, Chris

Probably.
The dot on the 3D STEP to denote pin 1 like the physical package may indicate Pin 1. But you can change the Polarity Dot Color in the 3D model by making it the same color as the package body. All 3D color changes are saved to FPX. |

OK, I think the easiest thing to do would be to change the dot color to black. The physical packages in these cases do not indicate pin-1 polarity. At least that's what their datasheets say. Kind of annoying. Diodes Inc has a bunch of these SOT-23-6 parts such that when the diode array is laid out in such a way that the part orientation is a don't care they leave the pin-1 mark off the package. Seems like more trouble/confusion than it's worth. Wish everyone would just keep it simple and specify a polarity marker whether it's needed or not.

Diodes, Inc. is the only component manufacturer that I know that uses the same Case Code for multiple packages.
In this scenario, the SOT-353 is the standard package and SOT353 for the non-standard package. We can't invent Case Codes because there are thousands of POD users that search by Case Code. In the future, we were planning to have the new PCBPOD website pulling the existing mfr. Case Code into a new part number search to increase the hit ratio. I don't know if we can do that with Diodes, Inc. |
