Adding surface features to a lofted and curved surface and extruding them

[Anonymous]

Hello, 

I am attempting to create a handle with a particular surface feature on a lofted cylinder.

I want to put those tiny, indented rectangles you see on the side of the part onto my model. Notice though that the part is lofted above the contour line then it begins too curve below it:

How does one go about doing this? I had thought you could use a projection to the surface but then I cannot extrude to give the feature its death within the part. 

Thanks

No need to project. Make sure your sketch is on a plane outside ot the part then on the extrude dialog use the distance To option then set a negative offset. You might need to toggle the Chain Faces option. Keep the corners sharp in the sketch then fillet the pocket and then pattern for the other pockets.

it seems like revolve would be a better method of producing that part than loft.  But, even if you want to stick with the loft for the main body, you might can use revolve for the indents.  In the attached file, features 3-7 create the indents.

Hey laughingcreek, it seems the file you shared cannot be opened. So what exactly do you mean by your process?

I am able to down load the file I attached and open it.  Maybe someone will come along and verify that the file works for them also.  In the mean time I made of screen cast stepping through that file, showing the different steps.

Worked fine for me.  I noticed that your sketches were not fully defined  😮  and the thread could probably use a chamfer lead-in, but otherwise fine.
