[Error] Invalid Input Thread Length

[Anonymous]

I get an invalid input thread length error when i try to change a thread where the height of the face is less than ~5mm and the thread sizes are small too (M1-M10). 

Thread is set to fullSize. Also fullSize false and thread length the same as height of the thread is throwing an error.

Is the problem within my code or is it a Fusion related error?

If I make the same thread in a higher body it is working!?

     ...
        # get the design
        product = app.activeProduct
        design = adsk.fusion.Design.cast(product)
        
        # get the root component of the active design.
        rootComp = design.rootComponent
        
        for item in design.timeline.timelineGroups:
            item.isCollapsed = False

        # define all of the thread information.
        threadFeatures = design.allComponents.item(0).features.threadFeatures #rootComp.features.threadFeatures
        
        # get thread
        thread = threadFeatures.item(0) #threadFeatures.item(threadFeatures.count - 1 )
        isInternal = thread.threadInfo.isInternal
        #ui.messageBox(str(thread.isFullLength))

        # query the thread table to get the thread information
        threadDataQuery = threadFeatures.threadDataQuery
        defaultThreadType = threadDataQuery.defaultMetricThreadType
        recommendData = threadDataQuery.recommendThreadData(0.2, isInternal, defaultThreadType)
        
        # create the threadInfo according to the query result
        if recommendData[0] :
            threadInfo = threadFeatures.createThreadInfo(isInternal , defaultThreadType, recommendData[1], recommendData[2])
            thread.timelineObject.rollTo(True)            
            #thread.setThreadOffsetLength(adsk.core.ValueInput.createByReal(0), adsk.core.ValueInput.createByReal(0.24), adsk.fusion.ThreadLocations.HighEndThreadLocation)            
            #thread.isFullLength = True

            thread.threadInfo = threadInfo
            design.timeline.moveToEnd()

One possible workaround:

- subtract a small Value of the length of the thread length

thread.setThreadOffsetLength(adsk.core.ValueInput.createByString(thread.threadOffset.expression),
                   adsk.core.ValueInput.createByString(threadExpression + " -0.0000000001"),
                   adsk.fusion.ThreadLocations.HighEndThreadLocation)

Seems like it is a Fusion 360 Issue with computing precision. @moderator Maybe create a support ticket?
