Extruding a Tapered Frame

[ksbarnes87]

I'm just getting my feet wet with Fusion 360 using some woodworking projects as practical examples to model out. Most things seem pretty intuitive, albeit there always seems to be multiple ways to define the same profiles.

That all said, I have a picture frame molding with a not-so-simple profile I'm trying to model out. In essence, it's your typical 45deg miter when viewed from the top, however each piece has a 7 degree linear taper...I can't seem to figure the best way to model this alongside the 45 degree miters.

I've attached a rather crude drawing to demonstrate the intended result; are there some preferred methods to accomplish this?

Looks like a simple Sweep of profile around a Rectangle and Split.

Can you File>Export and then Attach your *.f3d attempt here?

Attached as requested, the profile in question is the RearFrame sketch.

Works like a dream, thanks so much both of y'all!

Just as a followup, is there an easy way to split the resulting body into the 4 constituent portions? I've dabbled a bit with Split Body using a Construction Plane but the planes intersect in two locations.

Not really, you are wanting to split a looped body

Asking to Split the body with the 45 deg line in the sketch but Fusion delivers a no intersection error,  

Split Body uses one article at a time for cutting, So multiple cutters is not an option, 

The work around - I found two, both require some preparation, 

1. To cut the first sketch mitre line or Construction plane, let it cut both ends of the preview, with the extend tool option, No error, 

Then cut each of the other the 90 deg corners, the extended cutter will not be cutting an unselected body, 

and combine join the leg that was first cut intentionally.

Four split Body, and one Combine operation with existing sketch.

2. Edit Sketch and connect two mitre lines with a diagonal line, Extrude the three lines as a surface, and stitch them to one body, 

Split the frame with this body, no error, as per pic...., then other two corners with existing sketch...

Edit Sketch, Extrude, Stitch, Three Split Body operations.

Might help...
