I'm an electronics beginner making my first SMD PCB. <br> <br> Here is my test example project so far: [https://oshwlab.com/jimmer/optopus-proto2_copy](https://oshwlab.com/jimmer/optopus-proto2_copy)<br> <br> First I chose Everlight Elec PT26-21B/TR8 [https://lcsc\.com/product\-detail/Phototransistors\_Everlight\-Elec\-PT26\-21B\-TR8\_C131248\.html](https://lcsc.com/product-detail/Phototransistors_Everlight-Elec-PT26-21B-TR8_C131248.html)<br> <br> the 3D picture of the board showed the component upside down (it was mounted on the top layer with the bulb facing down through the board). DRC showed error of no hole in PCB. Also when I tested the purchase process to buy PCB from JCL that component was not available but I could change it to Everlight Elec PT26-21B/CT [https://lcsc\.com/product\-detail/Phototransistors\_Everlight\-Elec\-PT26\-21B\-CT\_C142317\.html](https://lcsc.com/product-detail/Phototransistors_Everlight-Elec-PT26-21B-CT_C142317.html)<br> <br> <br> The CT version does not show up in 3D view, so I wonder if it will be pointing up or down?  Am I OK to continue.with it ? Or, how to turn the TR8 version other way up? thanks
