Confused about what to do after projecting svg to surface

[Anonymous]

Hi,

I managed to project an svg onto the surface of an organic/curved object. 

What I would really like to do is make a shallow imprint (the opposite of extrude? Intrusion?!) of this projection onto the main body.

But I can't work out at all how to do that. And I'm just taking shots in the dark now.

I would love some pointers, I realize there I'm probably missing something on a conceptual level of best workflows in F360.

Another question related to this; Is there a way to group all the svg or sketch curves as one piece, even just for purposes of selection?

What I find happening is I have to manually select each curve component, but then when I exit out of a tool window the selection is gone and I have to tediously select each piece again.

Thanks

Go into the patch environment and patch the bottom of the blob.

Then stitch it to form a solid body.

Create an offset plane on either side of the object you want the recesses to be created from.

Project all the sketch elements to either of the sketches on the outside of the blob.

Start an extrude from one of the sketches and set the option in the dialogue from :Distance" to "To object" and select the blob as the object.

Provide a negative offset, which will define the depth of the imprint.

Change from "New body" to "Cut" and hit OK.

Thankyou so much @TrippyLighting!

I haven't quite got my head around it yet but will keep going over it until I do 🙂

One question : If I want the imprint to be on both sides of the object, would it the best strategy be to create the offset plane on the y-axis with the origin at the centre of the object, then make a two side extrusion from there?

I'll hopefully answer my own question while working through what you provided. 

Thanks again.
