Construct in 3D with 45deg bevel?

[Anonymous]

I got a very simple problem (I guess) but it is beyond my knowledge. 

I want to create a model, that has an indentation/bevel with 45deg angles, but I can't figure it out. 
I can almost manage with 3D sketches - patch - stitch - shell but feels like it has to be an easier way. 

I got a component with a opening in it. So I know the outside dimensions. 

I created the above model just to show what I'm trying to do, but it's wrong. The indentation (hope that is the right name) is the same heigth (check next picture)

More visible here, but the blue line marked, I want the hole that is below and above the indentation to be with a 45deg plate. Making the marked line needing to be shorter. 

Not sure If my need is clear, but tried just to draw plates (extruded sketches) and join them all as a large component, but also feels "messy". 

This needs to be 3D printed, so also have to have absolute control of the thickness, to match nozzle size and layer hight. 

Please help a noob 😞

You have 3 parts in the browser that are linked - you can't edit them, until you break that link.

You can make the tapered box a number of ways, 

Here are two, that used the 45 degrees on all sides, when making it.

You can also use the Chamfer, and Draft tools if the box exists in the first place

Might help....

It did work, thx 🙂

But I don't want equal angle on the edges. Reason is that I need to decided the dimension of the smaller (extruded) plate as well as the starting point. When extruding and then shelling it ends up on the inside of the starting "hole" but I need to grow outwards. 

So in my example, the short vertical edge should be 45deg, but then I need to set the "height" of the base plate and the depth on where it will end up, then the angle will be what it is for the above and below. closing "edge". 

Ended up just drawing two rectangles in 2 planes, 3D sketched and patched between. Not super smooth but worked.

Hi,

try ist as @davebYYPCU   recommends.

I know that I could have mentioned Loft for the two rectangles, but as there was no mention of anything other than 45 degrees, and no mention of the backplate to be driving the unknown angles.

No worries, you got it, that’s all that matters.
