Vendor Module Issue

[gkarthick87]

Hi,

I'm copying file 
from "vendor/magento/module-sales/Model/Order/Pdf/Invoice.php" 
to "app/code/Magento/Sales/Model/Order/Pdf/Invoice.php" 
and editing this invoice but the function is still calling from vendor module. 
How can I make this to work from app/code. 
Please let me know.

Hello @gkarthick87 

As per my guess it's because of your module name, because you are using namespace in custom module as

namespace Magento\Sales\Model\Order\Pdf;

which might pick the core class so it will be good if you change your module/vendor name.

and assuming that you've added preference in di.xml.

hope it helps.

Change module name and correct namespace properly will help you.
