I never ever wanted to create an impeller, but youtube shown me this video while i was learning some things with onshape and man this is awesome, you do so many clever things with it, it's just another level for me. Thanks a lot!
I guess I could say: "me too"! sometimes I feel led to design something and this software really make it easy to express an idea. Thanks for your feedback.
You make what looks complex so simple! 😯 1:05 Instead of an extra construction line you can temporarily make the 68 mm solid line into a construction line. When you're done with the dimensioning you can make it solid again.
@@cademist thanks to your tutorial, my professor was impressed by the projects i did in onshape so he appreciated my interest and enthusiasm. I also 3d printed this and the results were incredible.

Hey i have tried to do this shape but i cant get the spine to become one with the rest of the parts its there you can se the line but its just a line. Do you know what i do wrong?
Hello ! Thank you for this great tutorial. I am running into an issue related to this tutorial. Here when you are Sweeping the line, the extremity of the Line that is along the axis of the helix is somehow locked to this axis, and then when you sweep, the orientation of the line turns to correctly create the blade. In my case, I am using a 3D Helix (Helix spinning around a torus) created with Feature Script, and then when I sweep a Sketch along my curve, I would like that the orientation of my Line also turns along the path. It does not seem to work... Any idea ? Thanks in advance
You're welcome! Here is a link to my doc: cad.onshape.com/documents/3e059eb8144b06229a8783ff/w/78f2feef9b3feb26dabf0384/e/143ace69db16a93280574f3b?renderMode=0&uiState=6601bc9a09230601c7b4cdd1 If you share a link to your document I could have a look.
I'm sorry, but I don't see a suction face or a compression face, just a spline. have you seen a turbocharger or a centrifugal HPC? Or was this just for viscous fluids?
@@cademist so if it's too hard then what's the point eh? I was looking for techniques in CAD to get my impeller done -- I'll just pay SoftinWay and have them do it for us. This time TH-cam really let me down, as I looked high and low and nothing I've seen could actually compress air in a functional machine well.
This is great. "Thinking parametrically" is a challenge for me. I think it would have taken a while for me to figure out that the correct way to do this is to use "sweep" with "intersect", for example. Thinking in CAD is like learning a foreign language that has no common roots with your mother tongue.
I have no idea why most cad design tutorials of a part like just jumps straight in, doens't tell me why they take the dimenions or values they take, doesn't even show the 2d cad drawing with dimensions side by side to show how they're doing it and why they're doing a particular design step that way. It at least for me leaves it very vague.
Perhaps do another impeller design and this time take dimensions of say what if you have got blade dimensions with negative angle? let's your inlet angle is -30° & outlet angle is 30°. And there's no need for vanes or splitter blades.

The exact same thing happened to me!
You have no idea how helpful these videos are where u just show the process of designing a complex part. Love the videos man 👍
Thanks a lot for that feedback!
Great tutorial. I managed to create the impeller. Thank you very much!
You are very welcome!
Love these tutorials.
Glad you like them!

1:05 Instead of an extra construction line you can temporarily make the 68 mm solid line into a construction line. When you're done with the dimensioning you can make it solid again.
That's a great suggestion and would make the sketch even simpler!
that was AMAZING! i tried to do the same as in this tutorial and i fiinnished the blade succesfully!
I'm very glad to hear this!

Great Video!!

Great video!
Glad you enjoyed it
for that 8 degrees in the spline of the 1st sketch, were you trying to make it symmetrical?
something close to that...

to be honest, maybe you should think about drawing a bezier on a plane tangent to the side of the base then wrap it around, instead of just a helix?
That is another good approach, starting from a 2D-sketch, which would be projected to a 3d surface, if that works for you, why not?
I'm sorry, but I don't see a suction face or a compression face, just a spline. have you seen a turbocharger or a centrifugal HPC? Or was this just for viscous fluids?
Looks like someone's been hitting the engineering textbooks a little too hard lately! But seriously, educate a poor soul, what are we looking at here?

there are other options, a loft could assist, or maybe a fill-just experiment and you'll find your way to express yourself!

I take this approach to show a fast way to the object, but I'll take your suggestion of drawings for future videos!

I wish Onshape had a “curve through points” command
Just take the "3D fit spline" command. You can add as many vertices as you like!
