Cylinder/ sphere modification

zach_tippettszach_tippetts Member Posts: 2

Newbie here
I am making a candlestick based off the image here. I have most of it designed but I cannot figure out how to create the bowl portion at the top (that has the wavy edge). I'm also adding an image of what I have so far. Also, rather than chamfering the faces of the handle, I would like to add a rib, but that doesn't seem to work with lofts.

Any help would be much appreciated!
Zach

    Welcome to Onshape!

    Here's an example of one way.

    1. I revolved the bowl similar to your way
    2. I used some sketches and math to figure out the width for each scalloped cut
    3. cut one of them
    4. patterned the cut
    5. rounded the corners off

    As a bonus, I set it up to use a variable for the number of waves like so

    Nice job Evan.

    While I was doodling with wave count I found a limit that caused errors so I switched to a configuration variable to prevent the error. Too bad that standard variables don't have limits. Then I kept doodling and added some other window dressings that would limit errors while changing the count and made it a little prettier.

    Not sure how you built your handle without seeing your doc, but if you used lofts it would seem logical just to build the ribs into the sketches of the lofts.

    @glen_dewsbury Nice riff! I've run into that with variables sometimes. I think configuration variables like you have are the best solution to add limits, but I've also had times where the best workaround is to declare the variable, then later declare the same variable with a clamp() function like this example. This allows the limits to change based on other things. For example, the length limit could be a function of the diameter.
