Help designing a feature upon this model

Hello, Im trying to create what is almost like a rib but on the outside of an object that Ive created.

It’s really more for structural integrity as far as I can see. Included is a couple of photos showing an example that matches my request. Any suggestions would be great. Ive tried everything that I know but am falling way short?

Thanks in advance

Your second picture. Extrude that feature in that direction. Its just an extruded shape.

I tried that and its just isn’t working for me?

Share your 3D file, it would be easier to help you.

If the feature has circular cross sections use the Pipe command to create a pipe, and trim of boolean union the pipe and the object.

Create a line on the surface which is along the centerline of the desired feature. If the centerline is an isocurve of the surface then use ExtractIsocurve to create the curve. If not then use InterpCrvOnSrf.

Use the Pipe command to create a pipe with desired radius/radiii. Before setting the first radius select the type of end you want with the Cap=Option. Use SrfSeam to move the seam of the pipe inside the original object. Trim the pipe with the object or use BooleanUnion.

Thank you David!

I need to work on it a bit but I think its going to work!

Cheers,

Rick
