export stl and modeling threaded holes

[rory_the_king]

Hello everyone!
I open this simple simple thread:
- the characteristics of stl files to export from pro-engineer how do they vary? I need the highest quality!
- when I realize a thread (hole tool), how do I avisualize the same thread? I get the written but not the thread physically talking!
Thank you.
Lorenzo

It is always appropriate to give a title to the thread that lets you understand the topic, in this way it facilitates reading and research.
for the quality of stl:
when you open the "export stl" menu enter the zero value in the input boxes "height rope" and "angle control".
for the pro/e rope height will imply the best possible value according to the curved rays found in the geometry.
see image attached.

for threading, the representation of pro/e is symbolic (as for all cad).
therefore the threaded hole will be represented by a preforus and a surface corresponding to the nominal diameter.
the molding of the thread can be done with the helical sweep, but it is done only when it is strictly necessary.
These geometries would be very heavy to handle, especially in complex assemblies where you have thousands of screws and nuts.

ok for the title (you are perfectly right!).
thanks for turning off the stl file!
how does helical sweep work: for example filettaure iso m88x2?

Hi.

I place a pdf in which it is explained how to make a helical sweep.
Of course the odds of the hole m88x2 do not look for you:biggrin: ... a fast reading to the bald-ups and revenues easily.

Hello Maxopus!
then among the various threads found in literature I deduced that in my case the thread is iso metric triangular!
Attached I bring you some formulas and a sheet of calculations!
Now in the sketch plan you drew a simple triangle, but actually the tip is rounded!
Do you agree with me?

hi maxopus I tried to follow your method but always troubles!
I have to do a m88x2 thread of depth 15 mm!
I can't!
Can you help me?

Hey, Lorenzo, see if that's what you wanted.

as author of the little guide to make threads I thank for the quote, and it seems to me that it is what it does to the case of our friend.

Thanks to all the boys!
I picked up the model and managed to finish the thread!
Thank you again!
