- In this video, you will learn how to design an impeller. We will use the helix command, splines, surface revolve and sweep, If you are new to Onshape, or if you are looking to learn more about modeling impellers, then this video is for you!
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.
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!
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.
That's a great suggestion and would make the sketch even simpler!
Great tutorial. I managed to create the impeller. Thank you very much!
You are very welcome!
Love these tutorials.
Glad you like them!
Thank you so much! Your tutorial was very easy to follow
great to hear!
Great Video!!
Thanks for the visit
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.
there are other options, a loft could assist, or maybe a fill-just experiment and you'll find your way to express yourself!
Great video!
Glad you enjoyed it
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?
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?
@@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.
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!
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!
@@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.
@@flavius8278 which course are you studying? I'd love to see 3dprints of what you made! Thanks a lot for this feedback.
@@cademist I'm an IT engineering student and computer assisted graphics is a discipline we are learning.
If you want to, i will send you an Gmail with the pictures i took. 😉
@@flavius8278 so you study programming languages? My email is: avramjancu33@gmail.com
