Geometry puzzles me

Geometry puzzles me

Geometry puzzles me

(OP)
How do i go about creating this part? Looks like this cylinder has two different geometries 180 deg apart. what about those lips rounds?

RE: Geometry puzzles me

Kind of hard to see all the details, but I would use Surfaces to build the part.

Using Revolve and then Merging surfaces. Once the outer or inner surface is done, simply Thicken.

Again, I am sure this part can be done 100 different ways!

I fairly regularly model up filter canisters that are almost identical to this, I usually just use a shell approach.

Guys

 I still cant figure it out. So far, i have created the revolve feature (solid) only. How do i go about finishing the rest? i was thinking of a sweep feature but nah, what about a blend feature, problem is that radius is not actually a blend. It's located 0.156" away the rear face..

Steve mentioned merging the revolve features. So you meant to create one revolve for those 4 indents. Then use the merge feature

Please anyone.   

RE: Geometry puzzles me

Probably a hundred ways to do this part. The detail of the indent is a bit hard to make out on the sketch but a simple way would be:
1> create the cylinder as a surface with capped ends.
2> trim the top open
3> sketch a sweep path for the indent
4> sweep a surface profile of the indent along the sweep path
5> pattern on axis 4@360
6> merge
7> add rounds
8> thicken
done.

Loudman;

This sounds good. That's the approach I would take. But just be sure not to make your sweep a straight line (dont work).
