thread starting diameter

[gtsolid]

Hello everyone
I must insert a m19x1 as an attachment: I created a revolution in ø19 but my goal is not proposed in the drop-down menu, with no regulations.
Can you tell me what I can do?
I tried to put the nearest available, so much to try, but the lines on the drawing of the thread go abundantly forward, until the end of the
piece, if selection "until next". I would like them to stop at the edge indicated in the annex

when insert cosmetic thread, as standard choose (no one)
then where the symbol appears to you insert the thread core diameter which, of course, will be lower than the nominal diameter m19, which is on the tables.
I don't even know if it exists... .

m19no exists as standard so it should be inserted as defined by xxfast. for the length you choose as a blind term condition and you give the value

Of course you don't make life easy for those who have to answer.
Let's forget that you put such a circumstantial image that you don't see the m19 quota and you go to deduction that it is the one where the wrinkle 0,8 lies, by the way a roughness on the crest of the thread? ? ? ? )
we have deduced that it is cosmetic thread, but it could also not be so and then the cards in the table would change.
I understand that posting a property manager of the thread wanted to show too much information, but it would help us at least a little
or at least we would like to know what the edge indicated in the annex without having to guess

gtsolid, I have given a curious look at the discussions you opened and I give you my very vivid compliments not to thank for the answers received but above all not to give any feedback on the results deriving from these answers, whether they serve others.

with ra 0.8 means you electro-erosion that thread.....bah strange intentions... .

Those fillets actually cost me a capital if I want to make them mola, but the finish I get is perfect.
is not a standard so I fix myself as indicated by xxfast, or a custom made cosmetic thread.
thanks to all
