How to align previous sketch with newer sketch?

[Anonymous]

I am currently modeling an item that has a tapered side. There are multiple shelves, and as the piece gets taller, the shelves get shorter. After constructing the shelves and the sides, I am having trouble figuring out how I can update the shelves so that their bottom edges stick out  to the front edge of the side pieces. I figured I could project the points but I guess I can't project it since The sides came after the shelves? How should I do this? Attaching the model and some screenshots to help explain my situation because I'm sure I am butchering the description.

Also, if anyone would say I should have modeled the sides before the shelves, this was just the process I used in order to determine the actual angle the side pieces needed. So if I did the sides first I would have no idea what the angles should be.

Thank you for helping.

I have attached another version of the file where I have what I think is a hacked together solution. If there are are better ways, please share.

In the second file, you do not need the last sketch, for the last extrude

Extrude the front face of the shelf, to Object, and select the front face of the right side, making sure to click the chain Faces right side box.

You could do that for the top 2 shelves.

Might help.....

I actually was trying to figure out how to do the 'to object' extrude, but when I pressed Q i didnt get any sort of option like I normally do with extruding a sketch

Yep, pressing Q, for Press Pull, is not a short cut for the Extrude Command, 

Extrude is far more powerful, with Cut Join and Intersect options, to and from objects etc.

I know that you've mentioned that you can't design this rack from the side. But do be honest I don't get it (but that might be based on my missing experience in designing this things). Because of this, I did a little exercise and created the attached design.

I've created a main sketch where I've defined the width of each shelf, the distance between the shelfs or the distance to the bottom / top and this should match your design pretty well. What makes sense to me, because you more ore less did the same. Just with offset planes and sketches with a different perspective.

I guess I just mean that is how I go about doing the design. There is probably nothing preventing me from trying it, but my creative and design coming alive .. for me that works better from the front. I actually dont normally sit and sketch on paper before I hop into fusion. Maybe I should.

Nope, sketch inside Fusion, then add known dimensions, before long it will come together.

Plus one, for Willy's sketch, is what I was thinking.

I think I realized why I sketch from the bottom up instead of from the sides. I like to mirror and keep symmetric from the origin, and if I start with the side of something I don't really have that ability.

Here is one way to keep the root origin in the center:

@lichtzeichenanlage  has the right idea. It is just the most logical setup for something like this I think. There is no reason you can't set it up to be centered over the Origin if you want.

Here I have sketched on an Origin plane and used only the Extrude tool, often with the Symmetric option selected.

@chrisplyler: Nice. I was kind of lazy and I've  just fixed one extrude to point in the right direction.
