Adding Custom Threads for Selection in Thread Feature Menu

[Susan002]

How to add a missing or custom thread designation like M25x1.25, to the list of options available in the “Edit Thread Feature” window.

1. Find the ThreadData xlm files that Fusion uses. It lives here:
   

2. Create a copy of the ThreadData file that your custom thread is a family member of and name it something unique like… ISOMetricprofileCustom.xml
3. Using a text editor like Notepad++, edit the file to add the thread parameters needed.
4. Use an ISO thread calculator like this one:

1. Example for a  M25 x 1.25 Custom thread

<?xml version="1.0" encoding="UTF-8"?>
<ThreadType>
<Name>ISO Metric profile custom</Name>
<CustomName>ISO Metric Profile Custom</CustomName>
<Unit>mm</Unit>
<Angle>60</Angle>
<SortOrder>3</SortOrder>
<ThreadSize>

                                          skip to a logical location….insert a copy of an existing thread, then update thread values

                                           use an ISO metric thread calculator, (see step 4)

1. Save in the correct location, example: C:\Users\nnnnnn\AppData\Local\Autodesk\webdeploy\production\5873edb3ce0a7ce93d3ee911f7ba68d35a7e5862\Fusion\Server\Fusion\Configuration\ThreadData
2. Close Fusion then restart program.
3. Confirm that the new thread appears in the thread feature pull down menu, ensure you have selected your custom thread family as the “Thread Type”. It is ISO Metric Profile Custom in this example).

Fusion should be able to auto generate the Hole and Thread Note using the automatic Note feature. 

(Comment 2021-04-15 …appears only working for Hole info, not thread).
