Thread features in a drawing

[gjgoot]

Short question:

Is it possible to show the lines of the thread "extension". these lines are the crossover from the o.d. of the thread to the boresize. (30 deg.)

in autocad it are standard lines within a threaded hole.

in inventor i can not see or show them.

Thank you

What standard are you following?
I have never seen these (as you have drawn) in any standard.

Of course, just like in AutoCAD, you can draw in any lines you want in Inventor.
Drafting is still drafting, even if it isn't automatic (your (non-standard?) AutoCAD thread representation isn't automatic).
