mortis and tenon joint

don_howe

In my part I need to create a mortis and tenon joint. I've created the tenon part easily enough and I would like to use the same sketch to create the mortis but I'm having trouble selecting the sketch in order to remove the material. I thought I could work around this by taking a section view but I can't select it the sketch I need while in the section view. 

The parts involved are Post and Keel segment end.

The only other option is to create a sketch on top of the keel segment and create the mortis joint that way. 

Any thoughts on how else to do this?

Hi @don_howe if I understood correctly did not know what mortis and tenon joint was  until today. Use boolean subtract and keep tools. Hope it hwlps

using the boolean method you also dont have to set all the parameters on the cut extrude command, it will update no matter how you change the design even if one of the tenon sides ends up outside the mortice part.
it is quite powerful. you can also use one boolean operation to create all the mortices in one part on one go, this reduces the number of features that you need to keep track of, simply adding more tools to the subtraction.
