How to sweep in fusion 360
For more complex 3d modelling tasks like loft, we are going to need to create some construction planes to put our geometry on.
It is best to build the frame (construction planes and axis) for our component before we do the details (sketches).
We are going to create an offset plane from the XY plane under Origin.
This is found in the Construct menu under Solids.
Select this, then select the XY plane under the Origin folder in the Browser menu.
Set the distance you require and click OK.
Create a sketch on the offset plane of the profile shape you would like to loft from.
Then create a Sketch on the XY plane of the profile shape you would like to loft or transform to.
Execute the loft command by going to the Solids, Create, Loft command.
Select the First Sketch we created for the start of the loft, and select the second sketch for the end.
Click OK to create a new solid Body.
