Defaults in Length Parameter

marcus_bernsteinmarcus_bernstein Member Posts: 14 EDU
Hi Onshape Community,

I am setting up a featurescript where I need a set of length parameters. Is it possible to set the UI default to something other than 1"? 1" Totally breaks the model and looks awful as a default, while setting the default to .125" or something similar would make the Featurescript look nice. Is this possible just in length? Do I need to set up an enum with a bunch of options?

Thanks for the help as always,

-Marcus

    I find it not too convinient but seems like specifying new boundspec is the only way to do it. you don't really need all those options if you not care that your default parameter would look nice if to switch workspace units. the minimal definition of length bounds defaulting to 5 meters  is something like this
    const MY_LENGTH_BOUNDS = { (meter) : [-500, 5, 500] } as LengthBoundSpec;

    Also, if zero is an acceptible default, there are a couple built-in length specs that default to zero (ZERO_DEFAULT_LENGTH_BOUNDS, NONNEGATIVE_ZERO_DEFAULT_LENGTH_BOUNDS).
  • Not the easiest thing in the world but with enough futzing around it works great!

    Thanks for the help!!

    A slightly more concise syntax for doing this is:
            annotation { "Name" : "My Length" }
            isLength(definition.myLength, { (inch) : [0, .125, 1e5] } as LengthBoundSpec);
    
    The three numbers after inch are the minimum, default, and maximum values (respectively).
