so i basically have to design an integrated(solid) key onto a shaft, but have no idea how can i extrude the solid key until the wider bottom part/edge, which also happens to be rounded - if i just draw the key lines on the thinner shaft and extrude that, it will only do it in a square form for some reason, but i need the key to end as the same shape as the bottom part of the detail...

i probably cant even remember if i extruded the key part from a draft, but what i do remember is that it did not come out as rounded shape... and most certainly did not even snap to the edge of the bottom part...

so is there a piece somewhere that would have the most common design features laid out in a step-by-step tutorial somewhere?

I am not understanding what you want to achieve. Is it possible to post a pic of what it is you are wanting to do?

its basically a rounded shaft, with a wider area in the bottom like this:
||-------

so i would need to add a small key/extrusion to the "-------" part/shaft, which would end at the same width as the wider bottom part

even the lawn mowers and grass trimmers basically have that key on the shaft that keeps the attachments from rotating, but i need the key to be solid/integrated, aka non-removable

Welcome to the forum. I also don't understand exactly what you're referring to (you need to click on the "Full Editor & Preview" box below the Reply text box to post pictures), but it's likely you need a Revolve instead of an Extrude.

not sure if the previous post was visible before, but the key has to be only on 1 side, not around the whole shaft

Can you post a picture of what you need?

ok, i basically even need 2 different shapes then:

1st is the key coming out from the shaft and the 2nd thing is the oval shape in the bottom - are there any tutorials about these most common details somewhere or can someone make 1? (maybe add some pattern repetitions also to it then)
i cant even remember how did i manage to design the oval shape(which also needs holes tilted at the same angle as the oval shape actually!), but the key part i didnt even manage to figure out lol

Like this?

not really, but it was a bit hard to take a picture of the oval shape in the bottom...:

Maybe we need a base line. Are you new to Solid Edge or new to solid modeling all together?


Note, keys are implemented by cutting the keyway vs leaving a key standing proud for simpler machining. Unless perhaps its injection molded part or something.

i need the part(and a tutorial video) to be exactly the same way as it is written in the topic and on the pics

What have you gotten done so far?

that is also written in the topic and on the pics

NM

Something like that ?

probably would do, but the hole should be constant size and the key part should extrude outwards from the middle shaft, until the rounded edge of the lower/wider ring in the bottom (and should touch the ring too, not be in the middle of the shaft).
but how do you even make the lower oval part like that :x (and cut a hole into it)

I have pm an example (done in community edition).

If you can draw a 2d section view version of it I can model it up for you.
But general rule .. if its round its convenient to use revolve in other cases normal extrude.

i cant open that file tho... but can you make a video of the whole process? windows 10 probably even has a built-in screen recorder somewhwere in the start menu...
(and the key has to be only on 1 side, not revolving around the whole shaft)

Okej .. throw something together at work ..

ok thanks, thats pretty neat, but they key part should be exactly like it was at 02:19 - and just touch the edge of the middle ring below it and end with the same shape too, aka follow the rounded edge of the middle ring

Okay .. have redone the movie (see above) to include what I hope you are looking for ..

ok thank you, that looks nice, so i can probably finish my exact part now (soon)

i can probably get to the part really soon now, but atm i am even trying to edit/extrude some shapes from a really simple sketch, but it does not even allow me to extrude like a really simple square area from a sketch/face that already has 2 parts extruded from it?
i just get somekind of yellow warning sign saying something, but i dont even know what it wants...

so is there still somekind of really basic tutorial available somewhere that would show how can i extrude many shapes from the same exact sketch? plus it should also cut some of the sketch face that i want to get rid of and dont even want to extrude that one, just to get the actual shape that i'm looking for...

and is there a way to add all new lines and extrusions to 1 and the same sketch to not have to give a new sketch name to every new line that i just added etc?
