How do I join two parts, one has a square edge and the other has a circular edge.

george_campbell128

Really new to all this as I've just started into the world of 3D printing. I've watched quite a few youtube videos but I'm a bit stuck so looking for some help with my problem. I am trying to make a hose adapter, but the adapter also needs a hook as such to catch onto the extract part of my mitre saw. 
I've created the hose with my preferred sizes, I've also created the hook part, although when I was sketching it, I drew it with square lines, but the hose obviously is cylindrical.
Could someone help me out with how I can get the two pieces joined together?

Not sure how/if I can share what I have done so far, please don't laugh if I can, but just looking for a point in the right direction.

Thanks in advance for any help.

Hey @george_campbell128, welcome to Onshape!

We can help you out for sure. There is a share button in the top right of your document. Make sure you make it public, and turn on link sharing. Then simply give us the url here.

Sounds like the tool you are looking for is Loft, but I'm not for sure without the document link.

Hi Michael

I did look at Loft, but it didn't seem to like it when I selected the two faces.

I've shared the document and here is the link to it.

Any help would be greatly appreciated, as I'm so close to creating my very first part.

Thanks again.

Hi George.
If you're just looking to attach the hook a simple extrude/add will get you there.

Hi Glen

Thanks for your help with this, it looks like exactly what I was looking for.

I'll make a copy so I can edit and see exactly what you did, and learn from it for future.

I'd also like the 'hook' part to copy the same circumference, would I follow a similar process but without the add?

Thanks for all your help.

glen_dewsbury

Yes. You can select which parts to merge with or not during the extrude.

Sorry Glen, I also just noticed that the 'hook' is round the wrong way, would you be able to help rotate it, even though its 'joined to Part 1?  The 'hook' should be at the edge of the hose adapter, so it hooks onto the mitre saw.

Thanks 
George.

Sorry, I should learn to wait before posting.

I managed to resolve some of my previous issues. I managed to rotate the part and then copy your extrusion that you did, so it looks better. The only thing remaining to solve is putting the small curvature on the smaller part of the hook that doesn't touch the original Part 1.

Thanks again for your help with this.

It looks like you might benefit from going through the "introduction to Parametric Feature-Based CAD" training as you seem to be trying to use Onshape as a "mesh modeler", i.e. not as it's intended... Using transforms is definitely not the "right way" to locate a part like this in a parametric CAD. i.e. draw in the right place to start with!

Thanks Glen for all your help with this, I think I got there in the end, it's much appreciated for taking the time to help.

Eric, thanks for the link, I will have a look at that tonight.
