Creating a custom thread

Creating a custom thread

I'm trying to create a custom Square thread and have followed the instructions on how to create an xml file.

Here is an example of the xml I made.  It works when I do an external thread but when doing an internal thread , nothing changes.  No thread shows in the drawing.  Photo is below also.  Appreciate any help.

 

Thread is a square thread , 10 deg wall angle, 4 TPI.  Depth is only .031 instead of standard P/2 depth

 

<?xml version="1.0" encoding="UTF-8"?>
<ThreadType>
<ThreadForm>5</ThreadForm>
<Name>SQUARE Screw Threads</Name>
<CustomName>SQUARE Screw Threads</CustomName>
<Unit>in</Unit>
<Angle>10</Angle>
<SortOrder>15</SortOrder>
<ThreadSize>
<Size>1417</Size>
<Designation>
<ThreadDesignation>2.655</ThreadDesignation>

I've reported this bug here. By the way really you need to use a trapezoidal thread but that has a bug too and creates an incorrect formSmiley Sad

 

If you change the form to 0 it generates a thread just to the wrong form, this bug also shows up with the built in metric trapezoidal threads.
