Add thread callout to custom hole

Connor_LeCLaire

Hello,

I am trying to generate a blind tapped hole that has a counter bore (the counterbore acts as a locating feature for a sleeve but I will just call it a counterbore). When trying to make this using the hole feature wizard, changing any of the dimensions (such as counterbore depth or diameter) causes it to become a custom hole which does not support threads (for some reason). As such when creating a drawing, the thread is not automatically picked up in the callout.

To create the feature I need to use a simple tapped hole then create another extrude feature for the counterbore. It also requires two callouts when I'd prefer to have a single callout like the picture below. The picture was generated using the note tool in the drawing, however I'd also like to add an asymmetric tolerance to the counterbore hole diameter which notes does not support.

I would like to see custom holes that can use threads as well. Have you tried to make the tapped hole first and then the counterbored hole using the tap drill diameter after? It will create the hole you want but the downside is two separate hole callouts.

Yea my process is to either make a simple tapped hole and then remove extrude the counterbore or vice versa, both methods require two callouts which ideally I'd like to avoid but it seems like it's inevitable until they add support for threads in custom holes.

Does anyone have a good solution in this for 2024?

My satellite lab is running into this issue. We would like to slightly modify the countersink depth/diameter for some holes. It is a bit of a "corner case" in a satellite --- important for manufacturing the corner right

Thanks!

you could modify the attribute after the feature has been made. You just need to get the attribute, then change the map key that you want changed.

here is something I wrote a while ago. it should give you a good starting point. 

annotation { "Feature Type Name" : "Print Hole attribute" }
export const printHoleAttribute = defineFeature(function(context is Context, id is Id, definition is map)
    precondition
    {
       annotation { "Name" : "Entities", "Filter" : EntityType.FACE || EntityType.EDGE  }
       definition.ents is Query;
       
    }
    {
       var ents =evaluateQuery(context, definition.ents);
       for(var n=0;n<size(ents);n+=1)
       {
           var atts =getHoleAttributes(context,ents[n]);
           if(atts==[]) continue;
           you can change the attribute keys here to what you want them to be. this should override the hole callout for the drawing.
           println( atts[0]);
       }
    });
