Boolean_Bad_Input error

daniel_cravens

This feature is intended to extrude pin snap connectors along a line between a 3d printed part and then use opboolean to join the pins to the male half and to subtract the pins from the female half. The first steps of creating the sketchplane, skline, skcircles, and extruding the pins works as expected. However, the opBoolean call is generating the following error. 

If I comment out the opboolean call, I can perform a boolean manually by selecting the extruded bodies and the malepart.  I'd appreciate any tips as to what I'm doing wrong. The full code follows. Thank you in advance for your help.

        var sketchPlane0 = evOwnerSketchPlane(context, {

                "entity" : definition.edges

        });

        

        var extrudeDirection =  sketchPlane0.normal; 

        if (definition.flipped == true)

        {

            extrudeDirection *= -1;

        }

        debug(context, extrudeDirection);

Boolean Union is order specific and the first body is the parent. In your code you are adding the male body to the first pin so on the second loop the male body no longer exists. Swap the order of your qUnion.

Ah, that makes sense and works! Thank you!!
