Hello to all.
I’m finding myself in big trouble in trying to model the shape here below. I need this to animate a functioning sequence of an hydraulic circuit for training purposes. The image you see is the result of importing an OBJ exported from our CAD, but the drawbacks of this approach clearly appeared when I tried to render the image: odd shading, due to the high presence of triangles, and lot of un-needed geometry (it has just less than 32k vertices…). Using the edge split and decimate modifiers led to unsatisfactory results.
As far as the two side “sails” are concerned, I found a compromise starting from the central circle and extruding the various “separators” joining the outer circles and filling the resulting faces. I then joined this geometry with a bare resized cube underneath, to which I added some loop cuts before, with the hope of getting better results when using booleans to “carve” the holes in the lower part, afterwards.
The hardest part now is to model the central upper part. I couldn’t find any decent approach as to what to start from. I first tried to model starting from a plane (the aim was to be able to extrude the plan part down without having to join with the above mentioned mesh), but had to abandon as I couldn’t get the hemi-cylinder shape when arrived at the point shown in the left part of the image, then tried a cylinder that I cut in half (+ mirror modifier) and extruded down, but I always end up in not being able to create the two circular oring seats on top.
Is there anyone that could suggest a smarter approach?
