DXF and NPTH drill holes

Layout

Hi,

Im new to Kicad (and pcb in general)

Have imported this this dxf file:

and added it to the edge cut layer. What im not sure about is if the drill holes are correct or if I need to use/add NPTH instead? What is the best way to do this if? (planning using OSH park)

tnksā€¦

Circles on the Edge cuts layer will be milled instead of being drilled. In most cases this is a less precise solution and probably not what you want.

If you want the holes to be within the drill file you need to add NTPH Holes to your PCB.

Iā€™m doing the same thing right now. Iā€™ve imported a DXF file and in order to ensure that the hole will be drilled Iā€™m adding ā€œ1pinā€ footprints and removing the circles coming from the dxf template.

I also set the ā€˜1pinā€™ pad type property to ā€œNPTH, mechanicalā€.

What I didnā€™t understand is that in 3D view the holes with NPTH looks the same as the ones with ā€œthrough-roleā€ pad type.

Is this just a 3D issue ?

You need to set drill size and pad size to the same dimension.

I found this topic from 2015:

Yep, that did the magic !

but I think that would be much better if Kicad just set the values automatically when using NPTH. I think that others think the same in the link you provided. :wink:

thanks a lot, Rene.
