Am I on the right track for modeling a handheld mini vacuum nozzle?

By John Khoury on 08 Feb 00:52 6 answers 1 comment

My goal is to successfully replicate a household item that I personally own. I am currently modeling a little Dirt Devil hand held vacuum. I am mostly using surfacing techniques. I have applied two multi-section surfaces. The second multi-section surfaces was generated by two splines and a line. I am having a difficult time figuring out where to locate my points in order to display the section that curves in (this is shown in IMG_0495.JPG). I also trying to figure out how to implement the suction end. Could someone please give me tips on how to successfully render this item. Afterwards, I would like to make a retro design. Would it be worth it?
Please let me know if you need me to take a screen shot of a specific angle.

    Hi Friend, good morning!!

    I would like to ask you if you know how is the thickness for this part?

    another favour could you please take some dimensions of front view, because I can't see anything about it. and I would like to see that view, to give some ideas and some tips, to make more easer the desing. if you send us some additionals dimensions, it would be geat to send you the best tip.

    Thanks so much.

    See you later.

    I think the thicknes you can measure with a vernier or caliper!!

    my last comment is if you can help us with the angle, it would be great, I attach you a picture about it.

    From the outside surface to the inside, I measure it at 0.092 inches. Please see the section that I measured. I highlighted it. Does this help?

    As far as the angle, could you please share tricks of measuring the angle of this part. The piece is bulky and difficult to measure. I only have calipers and a plastic protractor available.

    I can't open your CATpart file since it was created with an educational license, but I can tell you how I would go about modeling that part.
    Looking from the large end, the part looks like it's made of 3 sections. The top almost rectangular section the bottom almost rectangular section and then the cylindrical sections on each side.
    Start with 3 planes one on each end of the part (large end and small end) and one in the between. Create a sketch for each profile on each plane and do a sweep between the 3 sketches.
    Do this for each of the rectangular looking sections and one cylindrical side, and sweep them.
    You should have 3 sweeps; one top, on lower and one cylindrical shape.
    Adjust the shape of the sketches so the intersection of those sweeps matches the way the 3 shapes intersect in real life.
    Trim the sections and fillet with a radius that looks good to you.
    Once you're happy with the look of the basic shape, work on another surface which will be the recessed section (where you have the transparent piece in the photos).

    Does that help?
