Plated slotted hole footprint

Plated slotted hole footprint


I'm making my transition from Kicad to Fusion 360. In my Kicad library I have a footprint of a toggle switch with plated slots. I can assign pad and hole X and Y dimensions. In Fusion 360 I can only find options for pad and hole diameter.



Searching the Eagle forum I found an advice to sketch the slot on the milling layer

Looking at the 3D view, doing this will make a slot in the PCB, but not a complete through hole inlcuding pads.

Are there any options to assign this to be a complete through hole? Will the hole be a plated hole or a standard contour cut?

Are there any other solutions to design a plated slotted hole footprint ?

Hi @vegardhumlen ,


Thank you very much for your suggestion.

I will forward your suggestion to our development team. Thank you.

This has been an issue that has bugged the hell out of me with Eagle since day zero.  Even my old Protel99 package enabled me to define a slot, which is something that is so commonly used in PCB layouts you'd think it would have been added to Eagle back in Version 1.2!!


As you've indicated, the way to do it is to specify the slot milling details on the Milling Layer and then specify that it is a through hole plated slot on your gerber.  I usually put "THP SLOT" on the milling layer inside the slot, and then put the same info in the notes when I order from my supplier.  Seems to get sorted to my satisfaction.


I also have success putting "NON THP SLOT" where the slot needs to be non-through hole plated.


Different PCB manfuacturers have different requirements with slot specification though, so best to chat to your supplier and see what they need.


It would be nice if THP slots was an easy to add feature to pads in Fusion360 though!

@vegardhumlen - when will plated slots be an option - this is available in many other ECAD packages...

I have not received any new information about this.  For my last project I used through hole terminals like this instead of slotted holes.

I make an SMD pad - and then add a slot in the middle on a MILLING layer. Defining it and resizing it later makes me scream obscenities that can be heard a hundred miles away (160km for those outside the USA). The SMD pad and the slot are NOT linked together and you CANNOT define a slot with a simple length, width, min radius.

Fiddly, yes it is. Like most everything in Eagle/F360.


As drawn.....



Trying to edit the slot to be a little wider......makes a major mess.
It requires you to calculate and type in numbers directly. Like I said - the obcenities can be heard from great distances.

Thank you very much for sharing @engineeringNCMXB .



There is no dedicated feature in Electronics at the moment, but you can use SMDs or long pads in the footprint editor and draw the contour of the slot in layer 46, Milling. 

Please check this out as reference. video about how to created slotted holes


Sorry for any inconvenience.

Hi @vegardhumlen 

I hope you are doing well!

Now we support the Slot PTH pad in Fusion 360 V2.0.13158+.

Please have a try, thanks!
