Asymmetrical Chamfer

[jerrodPHEAM]

I am working on a piece and I need to create an asymmetrical chamfer. I have tried the sweep function with a guide but I can't get it to come out. Any help would be much appreciated. The lines on the model show where I need the cut.

OMG it's hollow.  I admit not looking around first.....

I used Patch > Loft, take the two short lines.

Use the Loft body as a cutter with the Split body Command, Hide or remove the offcut.

Slide - drag the shell icon to the end of the time line.

Might help....

I've made a couple attempts, I still don't understand what you are saying. Which lines do I use the loft command with?

I got it! Thanks!

Won’t matter, has to be a pair, 

front and back, or left and right.

Change to Surface / Patch area, then 

Create > Loft I selected the short sketch lines at each end of the required chamfer.

You get a twisted plate, without thickness.

Then Use Modify > Split Body, Select your body, then Select the twisted plate.  Will cut the chamfer for you, and leave an off cut, and place a new body in the list.  Hide the off cut, 

Then click and drag the Shell icon in the timeline, drag it to the end of the Timeline to fill the chamfer hole.
