Cutting ribs on a nozzle
SOLIDWORKS Forums
3 months ago

Hey everyone,

 

So I'm trying to get the ribings on this nozzle section to look like this:

 

I'm having trouble getting the ribs in solidworks to look angled in.  As you can see, I clumsily tried doing this with a 3d surface loft, then cut extruding, but this doesn't cut along the contour of the nozzle.    Note: The ribs were made with Boss-Extrude6 and CirPattern1.

 

 

 

As a bonus, if you know how to get rid of the ribs on the inside of the nozzle that would be great too.  I tried surface offset and surface cut to no avail. 

 

Any help you can give would be appreciated.  The SW file is attached.  Thank you!

I haven't had time to look at your part but have you tried adding draft to the straight modeled rib?

Yep, what Casey said. Also, using the Rib feature will avoid those internal rib remnants.

Sweet thank you so much Mahir and Casey!  I knew I was approaching this all wrong.  

 

One last thing though, do you know what the best way to get rid of the inside excess would be?  (see below)

 

 

For the circular pattern I had to check "geometric pattern" otherwise I would get a "fail to rebuild error" (apparently because the sketch wouldn't intersect the nozzle).

I can't open your part file, but the easiest way to avoid those internal artifacts would be to not cut the center hole until after you're done with the ribs. Other options are to use Delete Face, Extrude-Cut, or Revolve-Cut for cleanup. Maybe you can modify the rib feature so that the feature pattern doesn't fail?
