Weekly Challenge Group

Inventor. 14 minutes. (including a short break...)

A key dimension to note is the 15.5mm dimension in View B is to the inside intersection. Whereas the overall dimensions in Section A-A are to the outside intersections.

Not as tough as it looks. CATIA V5:

But a good little challenge!

Shell is a good choice for this model.

I went with surfacing tools.

i just do more fillet steps but its really easy one (solidworks 2015)

Just for fun, I tried to see how few features I could do. 3 features.

If you did your shell last you would only need half those fillets.

Thx alot for your advice.i will try to do it in less steps

I found two different ways using FreeCad, but it took more work than inventor and CATIA. I now have "shell" envy and will have to learn how you did it so quickly using the shell tool. Anyways a good challenge!!

Do all operations only on the top face of a big extrusion. Then shell it.

Thanks Bob, it appears that FreeCad has something similar so this would work perfect. My final drawing was done using a pad, an additive pipe, and then a subtractive pipe, but using your method lets the computer do the work -- nice!!

Sketch, Surface Extrude, Sweep Cut, Sweep, Thicken, and no Fillets.

And at the end is the same thing, just different ways of doing it to open minds.

Which software Carlos? And how did you get the Surface Extrude into 2 pieces? There's nothing wrong with Fillets, as long as you don't have too many.

Jack, I agree, there is nothing wrong with fillets, simply trying different approaches and sharing.

I knew the question about the two pieces would come up. I thicken it, sweep cut, and remove thicken from history.

The easy to use Fusion 360.

Thanks for the questions.

I did it using 3 features and i think it's the minimum quantity of operations.

By the way, FeatureWorks made this part with 6 features.

Can someone add a new challenge?

Sorry if I am late to the party. I never knew this group existed. I used to take part in the Low Feature Challenge regularly. Here is my version. SW. 3 features. Same technique as Bob. Extrude, cut and shell.

definitely took me way more than 14 minutes, but eventually got it.
