I am still a new user to DS, always learning. Can someone gove me the correct steps to create a NPTH that will be used as a mounting hole? For some reason, my NPTH's never show up in Gerber Viewers, but the boards come correct. How do I specify the NPTH such that the Gerber Viewer shows them?
I create my Gerbers using these steps... http://support.seeedstudio.com/knowledgebase/articles/1176517-how-to-generate-gerber-files-from-designspark
I use this Gerber Viewer... https://www.pcbway.com/project/OnlineGerberViewer.html
Thank you,
