Component Layout Error - C319148

Hello, I'm having a bit of a strange error.  When i drop the footprint for [C319148](https://lcsc.com/product-detail/USB-Connectors_XKB-Connectivity-U262-161N-4BVC11_C319148.html) in my project, it gives a DRC error for the alignment pin and pad being too close together. It's giving me a DRC Clearance issue between the ground pads and the hole.  The part that makes me wonder if i'm doing something wrong, is the error is coming from the supplied component itself.  i was wondering if anyone has any insight on this or what i can do to get around it.  I'm using the stock 0.152mm clearance requirements (as i am unsure if changing it will cause issues with the pcb production). ![image.png](//image.easyeda.com/pullimage/if13PN9h9oeEQ7zm1c1wMABKXcrW0VkWPCjqLM9q.png) ![image.png](//image.easyeda.com/pullimage/ixzeIIoLj0JtTgsfgmVBwfvMSNRbmPoJB8fKobhn.png)

one little adendum, as I am looking at this a little closer, i see that in the footprint, the footprint for the alignment hole and footprint for the ground do slightly overlap. What I am wondering, is this an error with the component design in EasyEDA, or is this an error I should be able to bypass? If so, what is the best method to bypass the errors. ![image.png](//image.easyeda.com/pullimage/iAt5yF3xFpjfCAy9830NFgiIKfBSrLW7luztTMwC.png)

I have checked the footprint against the datasheet and there are dimensional inaccuracies. I have submitted an error report: Dimensions are incorrect to datasheet: [https://datasheet\.lcsc\.com/szlcsc/2002271811\_XKB\-Connectivity\-U262\-161N\-4BVC11\_C319148\.pdf](https://datasheet.lcsc.com/szlcsc/2002271811_XKB-Connectivity-U262-161N-4BVC11_C319148.pdf)<br> <br> For future reference, you should do this for any symbol or footprint errors. 1. Check the symbol and/or footprint against the manufacturer's datasheet; 2. Select the part in the Library and then do Right-click > Report Error: ![image.png](//image.easyeda.com/pullimage/uiBC830E0alYnE7bWaq7uMgLoRZ19e17U4nBvitX.png)

@andyfierman interesting.  because when i checked the measurements, it was within tollerence. they specify +/- 0.05mm as the dimensional accuracies. the two offending holes are 0.05 over, as well as slightly off.  i figured it was to help with alignment.

It's not just the diameters, the relative position are wrong.
