Looping through a Const list

Nath_McC

Hi All,

I have a list of values in a const list 'arraySize" and wanted to know if it is possible to have a value loop through them.
My example is below, and the value I would be looking to show is:

        var myDiameter = 13 * millimeter
        var actualDiameter = "This should be the value from the the const table, e.g. 9/16″  (14.28mm)

How would I go about having it loop through the below list to find the value it is less than? The value I need to get, I believe, would generally be from a getLookupTable(arraySize, definition.actualdiameter).dwgValue however, the myDiameter value is not from user input as it is a calculation from the code based on the bounding box size.

Thank you in advance.

The list I'd like the loop through is below:
export const arraySize = { "name" : "stockSize", "displayName" : "Stock Size", "entries" : { "3" : { "metricValue" : 3, "dwgValue" : "3mm" }, "3.17" : { "metricValue" : 3.17, "dwgValue" : "1/8″ (3.17mm)" }, "4" : { "metricValue" : 4, "dwgValue" : "4mm" }, "4.73" : { "metricValue" : 4.73, "dwgValue" : "3/16″ (4.73mm)" }, "5" : { "metricValue" : 5, "dwgValue" : "5mm" }, "6" : { "metricValue" : 6, "dwgValue" : "6mm" }, "6.35" : { "metricValue" : 6.35, "dwgValue" : "1/4″ (6.35mm)" }, "7.93" : { "metricValue" : 7.93, "dwgValue" : "5/16″ (7.93mm)" }, "8" : { "metricValue" : 8, "dwgValue" : "8mm" }, "9.53" : { "metricValue" : 9.53, "dwgValue" : "3/8″ (9.53mm)" }, "10" : { "metricValue" : 10, "dwgValue" : "10mm" }, "11.11" : { "metricValue" : 11.11, "dwgValue" : "7/16″ (11.11mm)" }, "12" : { "metricValue" : 12, "dwgValue" : "12mm" }, "12.7" : { "metricValue" : 12.7, "dwgValue" : "1/2″ (12.7mm)" }, "14.28" : { "metricValue" : 14.28, "dwgValue" : "9/16″ (14.28mm)" }, "15.87" : { "metricValue" : 15.87, "dwgValue" : "5/8″ (15.87mm)" }, "16" : { "metricValue" : 16, "dwgValue" : "16mm" }, "18" : { "metricValue" : 18, "dwgValue" : "18mm" }, "19.05" : { "metricValue" : 19.05, "dwgValue" : "3/4″ (19.05mm)" }, "20" : { "metricValue" : 20, "dwgValue" : "20mm" }, "22" : { "metricValue" : 22, "dwgValue" : "22mm" }, "22.23" : { "metricValue" : 22.23, "dwgValue" : "7/8″ (22.23mm)" }, "24" : { "metricValue" : 24, "dwgValue" : "24mm" }, "25" : { "metricValue" : 25, "dwgValue" : "25mm" }, "25.4" : { "metricValue" : 25.4, "dwgValue" : "1″ (25.4mm)" }, "28.58" : { "metricValue" : 28.58, "dwgValue" : "1 1/8″ (28.58mm)" }, "30" : { "metricValue" : 30, "dwgValue" : "30mm" }, "31.75" : { "metricValue" : 31.75, "dwgValue" : "1 1/4″ (31.75mm)" }, "34.93" : { "metricValue" : 34.93, "dwgValue" : "1 3/8″ (34.93mm)" }, "35" : { "metricValue" : 35, "dwgValue" : "35mm" }, "38.1" : { "metricValue" : 38.1, "dwgValue" : "1 1/2″ (38.1mm)" }, "40" : { "metricValue" : 40, "dwgValue" : "40mm" }, "41.28" : { "metricValue" : 41.28, "dwgValue" : "1 5/8″ (41.28mm)" }, "44.45" : { "metricValue" : 44.45, "dwgValue" : "1 3/4″ (44.45mm)" }, "45" : { "metricValue" : 45, "dwgValue" : "45mm" }, "47.63" : { "metricValue" : 47.63, "dwgValue" : "1 7/8″ (47.63mm)" }, "50" : { "metricValue" : 50, "dwgValue" : "50mm" }, "50.8" : { "metricValue" : 50.8, "dwgValue" : "2″ (50.8mm)" }, "53.98" : { "metricValue" : 53.98, "dwgValue" : "2 1/8″ (53.98mm)" }, "55" : { "metricValue" : 55, "dwgValue" : "55mm" }, "57.15" : { "metricValue" : 57.15, "dwgValue" : "2 1/4″ (57.15mm)" }, "60" : { "metricValue" : 60, "dwgValue" : "60mm" }, "60.32" : { "metricValue" : 60.32, "dwgValue" : "2 3/8″ (60.32mm)" }, "63.5" : { "metricValue" : 63.5, "dwgValue" : "2 1/2″ (63.5mm)" }, "65" : { "metricValue" : 65, "dwgValue" : "65mm" }, "69.85" : { "metricValue" : 69.85, "dwgValue" : "2 3/4″ (69.85mm)" }, "70" : { "metricValue" : 70, "dwgValue" : "70mm" }, "76.2" : { "metricValue" : 76.2, "dwgValue" : "3″ (76.2mm)" }, "80" : { "metricValue" : 80, "dwgValue" : "80mm" }, "82.55" : { "metricValue" : 82.55, "dwgValue" : "3 1/4″ (82.55mm)" }, "88.9" : { "metricValue" : 88.9, "dwgValue" : "3 1/2″ (88.9mm)" }, "90" : { "metricValue" : 90, "dwgValue" : "90mm" }, "95.25" : { "metricValue" : 95.25, "dwgValue" : "3 3/4″ (95.25mm)" }, "100" : { "metricValue" : 100, "dwgValue" : "100mm" }, "101.6" : { "metricValue" : 101.6, "dwgValue" : "4″ (101.6mm)" }, "110" : { "metricValue" : 110, "dwgValue" : "110mm" }, "120" : { "metricValue" : 120, "dwgValue" : "120mm" }, "127" : { "metricValue" : 127, "dwgValue" : "5″ (127mm)" }, "130" : { "metricValue" : 130, "dwgValue" : "130mm" }, "140" : { "metricValue" : 140, "dwgValue" : "140mm" }, "142.4" : { "metricValue" : 142.4, "dwgValue" : "6″ (142.4mm)" }, } };

Something like this, if I understand the ask right? https://cad.onshape.com/documents/2b6da5e47387308bdd243143/w/af22172ac903e5a92e494e46/e/7201b9d3b33162bcc59aed32

This assumes the "metricValue" field is in millimeters.

I would ideally start off with arraySize.entries as a map indexed by numbers (rather than stringified numbers like "142.4"). Then iteration through the map would happen in that order and it's a simple for...in loop to find the first value greater than your input.

Hi @_anton,

You are correct that the metricValue is millimeters.

That I've what I was looking for, Thank you for the working example.

My only question is it seems that "myLength" is 4.1mm, but it has picked the "1 5/8″ (41.28mm) , metricValue : 41.28", where really it should actually be the "3/16″  (4.73mm) , metricValue" : 4.73"

Hmm, I'm seeing the expected results (former for 4.1 *cm*, latter for 4.1 *mm*).

Though I did not test my code very thoroughly. :P

I now see that. It works brilliant, and I should be able to integrate it with the rest of my code. Thank you!
