Contour a rectangular model

[Anonymous]

 Hello all, new Fusion 360 user here having tons of fun and becoming more fluent everytime I use it.

 My question is how to push/pull an contour in the Model workspace. 

An example: http://www.warmoth.com/Guitar/Bodies/images/tele_contour.jpg

My model at the moment would be the "uncut tele".

It seems to me I should be able to anchor 2 points on the body edge and pull an arc on the Z plane down but I am at a total loss. I have looked for tutorials to accomplish my goal but I believe I am asking the wrong questions.

Any help would be greatly appreciated.

Thank you for your time- Jake

welcome to Fusion, @Anonymous.  For some reason, Fusion attracts a lot of people into modeling guitars and guitar bodies (myself included).  There are a couple of ways to attack this problem.  I tend to use the "Sculpt surface as a splitting tool" approach shown in this thread:  arch-top-guitar-model.  The basic idea is to define a Sculpt surface, push and pull it to get the desired cutout, then split the body using that surface.  Finally, add Fillets to get nice blending.

Just do a search on "guitar" on this forum, and you will find lots of people who have good ideas and will offer lots of help.

 I think the allure to fusion for me was how it is geared very much toward CAM and that a guitar is a very simple machine that has seemingly limitless design potential.

 I saw your blueflake Tele. Looks awesome!

 As you mentioned in another post about the difficulties of design being precise measurements, I have designed this model exclusively parametrically. Sculpting is a workspace I would like to avoid if at all possible. 

Is it possible for me to insert a plane where the contour would start on the guitar body top, and define an arc to push the mid point downwards on the Z plane along the guitar body edge?

Sorry if I am hard to understand. I speak in word salad sometimes.

Yep, you can do this multiple ways.  And, I, also, appreciate the advantage of wanting to keep it all parametric.  For what I was trying to do (a contoured top), I couldn't figure out an easy way to get that contour parametrically.  But for the "forearm" and "belly" cuts, that geometry is simple enough that you could do it with a parametric surface instead of a sculpt surface

Here is a very quick, crude screencast showing the idea for the "belly cut".  Define a few sketch planes, create some splines on those planes.  Then, create a surface loft through those curves.  Then, play around with the sketches to get the shape you want (you can do all kinds of dimensioning if you want it to be even more parametric).  Then, use Split Body to do the split, and remove the part you don't want.

 Jeff you are the man!

I also figured out an alternative method :

On the guitar body sketch plane, I drew a line between 2 points on the body edge.

I then extruded it to the depth of the cut I was looking for .

Then i created a plan along the edge I drew and agled/cut it so that it passed through opposite sides and cut original body with the new piece I created.

Thank you. I am sure I will be back for more help!

The amount of methods possible to solve one problem is staggering btw. I love how intuitive the program is.
