When I export my part to Altium there is no white dot on the 3D model as show here.  Thoughts? Thank you.

Is this for the SOP component family? We need the URL link to the datasheet so we can reproduce the error. ------------- Stay connected - follow us! https://twitter.com/PCBLibraries" rel="nofollow - X - http://www.linkedin.com/company/pcb-libraries-inc-/" rel="nofollow - LinkedIn |

It is an SOIC-8. The Analog Devices R-8 package. Here is a link to a part that uses that package. http://https://www.analog.com/media/en/technical-documentation/data-sheets/AD8675.pdf" rel="nofollow - https://www.analog.com/media/en/technical-documentation/data-sheets/AD8675.pdf

This package is not a metric pitch SOP. It is a 50 mil pitch SOIC. The Polarity Marker is a Chamfered Body along the entire upper edge of Pin 1.  ------------- Stay connected - follow us! https://twitter.com/PCBLibraries" rel="nofollow - X - http://www.linkedin.com/company/pcb-libraries-inc-/" rel="nofollow - LinkedIn |
