Pass Boolean through FS dialog

CAD_SSPCAD_SSP Member Posts: 45 PRO
At present you cannot pass a boolean through a feature script dialog, this is ideal if you want to hide a feature in certain configurations (rather than forcing them to fail which seems an odd workaround to me).

Something like:
<span style="background-color: transparent; color: inherit; font-size: inherit; white-space: pre-wrap;">annotation { "Name" : "My Boolean Variable" }
</span><span style="background-color: transparent; color: inherit; font-size: inherit; white-space: pre-wrap;">definition.myBooleanVariable is booleanVariable;</span>
A current workaround is to pass the variable name in as a string (without "#") and then check if it is a boolean and so on but is not very intuitive as you want to include the "#" but that stops it working.

    I'm not sure I understand this request. FeatureScripts can defintely use boolean inputs. They look like checkboxes.

    annotation { "Name" : "My Boolean" }
            definition.myBoolean is boolean;

    @mahir what I am trying to achieve is this:
    If your partstudio contains a variable that is a boolean such as "#Showitem = false" you cannot pass this boolean value into featurescript (as far as I can see).
    A boolean input as you state is a checkbox, you cannot assign a variable value or a formula to it.

    The only workaround I have found is to us a string query and pass the boolean name in as text, then you can use the use "getVariable" within FS to check the value i.e.
    <div>annotation { "Name" : "Hide If:" }
    definition.hideIf is string;</div>

    pass in "Showitem" without the "#" and then do a check to see what if anything was passed in:
    <div>var hideIfcheck is boolean = false;
    <span>if (definition.hideIf != "")
    </span>{
        try&nbsp;
        {
            if (getVariable(context, definition.hideIf))
                {
                     hideIfcheck = true;
                }
        }
        catch (error)
        {
            reportFeatureWarning(context, id, "you have used a non Boolean or non-existant variable");
        }
    }</div>
    This is a messy workaround as you instinctively want to put the variable name when you type it with the "#" but I cannot find a way of removing that within featurescript.

    Have you tried isAnything? That will take a variable as input.

    isAnything(definition.myBoolean)

    A code snippet for Neil's suggestion:

    annotation { "Feature Type Name" : "Take Boolean" }
    export const takeBoolean = defineFeature(function(context is Context, id is Id, definition is map)
        precondition
        {
            annotation { "Name" : "Boolean" }
            isAnything(definition.bool);
            
        }
        {
                if (!(definition.bool is boolean))
                    throw regenError("Boolean should be a boolean", ["bool"]);
        });

    But you may want to consider just using a normal checkbox for your feature and then using configurations to toggle it rather than variables:

    That's what I was thinking. Here's an example of configuring the Unsupressed property of a feature, which seems to be exactly what you'd like to do. In this case I used a list input to control suppression state of the circle and square, but I used checkbox inputs to independently control the suppression state of the triangle and pentagon.

    Thanks, isAnything is exactly what I want.

    Configurations are perfect for most applications but don't suit this particular case.
