the thread is not appearing. What could be a reason for this.
On 3D model the thin line is shown.
Is the chamfer the same diameter as the thread? What happens if you project a view off your view, do you see the thread.
And you cannot insert a thread in a part model. And does the model have the cosmetic thread in the feature manager tree?
You are right. If it's the same diameter than the thread it won't show. Sometimes it shows, strangely this time it didn't.
Right click on the chamfer circle and select select other and see if the cosmetic thread appears in the list.
