Machine Selected Surface and extended length

[jfkarls]

I trying to program a selected surface and keep the toolpath to only the selected surface and add extended lead in/out if possible

I currently program in SmartCAM and to mill a 35 deg angle on a slide for a mold I select my surface and add .500 to the lead in and out so it machines past the surface so it has a good transition when it starts cutting.

I am hoping to switch to Fusion but I can't figure out how to do the same exact type toolpath in Fusion. SmartCAM is a simpler CAM software so if it can do it I would hope Fusion can. Currently if I use the additional offset it wraps around the part, I want it to continue in line with the surface like a normal 2D contour toolpath where you can add a linear extension.

I have tried every 3D toolpath with no luck. I will attach pictures and the file and hopefully someone has already figured this out and I am over looking a really easy fix.

I will attach pictures of the part and toolpath in fusion and how I currently program it in SmartCAM where it works perfectly.

Here are some more attachments and the part we are trying to machine.

Sadly, it's as you've found; we don't have the "direct extensions" that other software has. I know that PowerMill (an Autodesk product) has that option, but as of yet, it hasn't made its way into Fusion.

So, to work around that, it's a small matter of making some Patch Surfaces:
