Scaling top of a cylinder

[anders.rustad]

Hi

I am quite new to Fusion 360, but I am not able to find a solution by searching (maybe I do not know the correct phrase to search for).

I have created a part for a kitchen fan we have that I want to 3D-print.

I have created a model by creating a few sketches and extruding parts from it to create bodies.

I have extruded all of the cylinders from a sketch and I want to scale the top part of the cylinders (make them smaller). I have tried the draft tool, but I am not able to scale it the correct way. I am only able to select the top face (not the face around the cylinder) and then the scaling goes the wrong way so the bottom part is scaled inwards or the bottom parts is scaled outwards, but not the top part inwards.

Do you have any tips on how to do this?

You should be able to use the Draft tool, but I think you are making selections in wrong order/location.

Select the planar face at the base of the cylinders, then select the cylinders.

I exaggerated the draft angle in attached image to make selections obvious.

But you could do the Face Draft as part of the Extrude feature.

Simply right click on the Extrude and select Edit Feature.

Drag this circle for Taper and then enter whatever taper you want.

Thank you.

I was able to try both solutions now and they both worked as I wanted.

You are doing a good job of fully defining your sketches - but I might suggest a different dimensioning scheme.

Edit Sketch2 and notice that I removed many of your dimensions.

For example, all of the cylinders can be controlled with one diameter.
