Having Problems Creating Rib! Please Help. 2

[Manley23]

Hello All,

I am trying to create a rib between a flat wall and a cylindrical surface (image attached), but not able to achieve desired result as some material remains on the rib portion which avoids a smooth blend. Please help. Also there is a 2deg draft on the cylindrical surface.



Thanks in Advance.

Try delete face or replace face to get rid of the small triangular faces where the rib meets the cylinder.

Hello Cowski,

Is there any other simpler straight forward method like a rib feature we have in Solidworks?

 

[Manley23]

Hello Cowski,

Thanks for your your reply. I tried to delete faces and it looks good at first sight (Image 1). But when I try to look at the rib from bottom, there is still some material left over (Image 2). When I try to blend the edges you can easily find out that there is not a smooth blend between the rib and the cylindrical feature (Image 3). If I first delete faces and then trim off extra material, it still does not serve my purpose (Image 4). Please suggest.


Thanks in Advance.

I'm not familiar with Solidworks.
In NX, the "dart" command might do what you need. Without seeing your model, I'd have a hard time recommending a "simpler" method.

Ok Thanks for your help. I'll try the dart option.

Depending on what you want that transition to look like, you might have to build the top face of the rib with something like "through curves".

How about removing the draft from the Cylinder. Unite cylinder and rib, then add draft to cylinder face with Synchronous modeling? that should give you the correct transition.

I have a solution attached.... wouldn't say it is an easy method. I would be interested in seeing a picture of this model created in Solidworks to understand your desired outcome.

 

[Manley23]

Thanks JohnVincent. Your solution is good enough for me.

Yes there is a Rib feature in NX. From NX9 and later.

In this model, you connect a "slanted" planar face to a circular face, what is your expectation of the resulting geometry , should the resulting edge be circular or linear ?

Regards,
Tomas

Thanks Tomas for your Reply. I am actually using NX7.5, so I dont think rib feature is available. Actually what I require is a smooth blend at the intersections i.e. linear where the rib meets the planar face and circular where the rib meets the cylindrical face.

I am not sure if the move edge command is available in NX7.5, but in NX9 it does the job.
I am the kind of guy that always likes to minimize the number of features, so this one is my kind of thing.
No curves or projections, just sketches and features.

In case you cannot open a NX9 part, here's a picture.
