small mysteries of sw

[genesis1975]

I designed a piece for a welding mask, and finally I saw that it was better to make it in two parts joined together with two screws..so I pulled a sketch line where the piece was cut...c is to say that right in correspondence from the sketch line, of the cutting plane, started a blind thread that I had done and that was identified by the two concentric centers. .now when I go to do the function divide and save the two bodies and then I go to make the table of that with blind thread, here is that it removed the circle of the thread leaving it only at the end of the hole...the hole is no longer threaded. . What went wrong. ..unfortunately I have no images because I came out of work...and who imagines what happened?

I made it home, the thread started from the vertical line, now it is moved and then it doesn't even end with the end of the hole....it generated a mistake... I know why

This is the part I have divided

We start by saying that you do not need to make a sketch line to divide the part, but just select the face from which the threaded hole starts.
the hypothetical problem is due to the fact that the threaded hole does not start from the inner plane, but from the outer one.
solutions are:
to make the hole on the correct face (if not done so)
b move the split function above the threaded hole

2 things do not understand of this file:
why do a sketch and then do the guided drill that already has the dot sketch inside it (double work, double sketch to manage, double reconstruction); you do the sketch of the guided hole function just, if you need to change a double click on the function (not on the sketch) and you change

Why save bodies externally? makes sense if you need to change the model or you have to send to the cnc or make a step, but if you do it only for the table has little use since in the table you can choose which body to display besides having additional files and references to manage

the thread left the inside. ..on the sketch of the hole I noticed later, now I am not changing it again and on saving the bodies externally....it was the first time I used to divide...thanks
