Adjust Sketch Position on Face

3D Design
1

Hello, I am making a stand for a cylindrical bluetooth speaker.

I used projected curves that allowed me to get the shape I liked. Only I come across a problem that I can't solve and that has already blocked me in the past.

I don't know how to adjust my sketch on a surface before I do my sweep (either it's not big enough, or it's too big). 

On the following screenshot I would like to make sure that the body at the base of the arrow is better positioned (at the top of the arrow).

I tried to project a curve but I can't do a sweep with it 

And there is always a gap 

Thanks in advance

You have to convert your projected curve into a 3D sketch

Thanks for your answer, but when I create a 3D sketch and convert my projected curve. The scan function refuses my profile because it is a closed non-planar 3D sketch (not allowed)!

I would like to help you but I don't really understand your question

In addition, as you have a version higher than mine, I can't open your file

it's your projected curve (once it's been projected)

that you have to convert into a 3D sketch

you also say that the 3D sketch is firm and that's why you can't do any sweeping

well cut your 3D sketch a little bit, do your sweep

and then  you will do a smoothing between the 2

Clearly explain what you want  because via your image 1 and 2 I have a little trouble understanding

Hello

Sorry, I'm going to rephrase it a little better!

I'm looking to make a stand for my speaker which is cylindrical in shape. Here is an overview of the result I am looking to achieve:

Seen from below (I'm trying to make a kind of X that connects the 2 sides (well it's not clean but the idea is there): 

I do all this by symmetry and I wonder how to make the first part of my X (the selected part):

I projected a sketch on the face but when I do my sweep I have an offset:

So I wonder how to adjust a sketch correctly on a surface, or rather how to get matter out of a body properly without there being pieces sticking out.

For all the sweeps I've done, I've used a lot of projected curves. Is this the most appropriate way to make this kind of shape?

EDIT: By the way, do you have any resources to learn more about how the software works?

Hello @KarmaKat 

if I may 

Mechanically speaking 

your X is not I think the best walkthrough 

to stiffen your speaker stand even if we know that your speaker is not very heavy

What is the material intended for this support

Re, it's PLA plastic.

"your X is not I think the best walkthrough"

Yes, it's true, but I set myself the goal of exploring several forms to experiment.

What would you recommend as a shape? Knowing that I want it to respect a certain design

re @kamarkat

here is your JBL flop type speaker support part

made according to your posted views

The support profile is indeed coincident with the speaker

see via the file how I proceeded ;-)

Thank you very much, frankly you treat me. I hadn't imagined doing this so simply at all. It makes me realize that I don't quite master the basic tools. 'Well I would have learned some stuff by exploring.

 

Thanks again

as they say all the roads even in Rome 

and why make it complicated when you can make it simple ;-)
