threaded interference in solidworks

[Gisnio]

Hello, :wink:
are new to the forum (I carry out a mechanical drawing course in which we use autocad and solidworks)

in solidworks I have a problem with threads and interference in the set
Although lives and mothers are of the same size, interference arises.

I tried to figure out how to solve the problem by looking at old posts but I only saw how to disable interference detection (generally) even when there are no correct mating conditions.

Would you know how to handle the problem?

thanks to all in advance for the help

It is obvious that vine and hole give interference. otherwise the thread could not have taken. If you read this pantry you will understand why.
to ensure that fixation interference is diversified you must add the isfastener variable in file properties. in the guide, that no one ever reads, is explained how to do. http://help.solidworks.com/2012/italian/solidworks/sldworks/c_interference_detection.htmhttp://help.solidworks.com/2012/ita...s/c_interference_detection_with_fasteners.htm

thanks maximum I immediately take a look.. .

definitely it is normal that din912 screw has stem/hole interference. If you don't want to change the type of drill you do as a cosmetic thread to remove thread.
depends on how you're used to working and what you want to get. if you don't have to have interference is as convenient as you do printed pieces help you understand how much thickness of real material remains around. As much as if you realize you print plastic and then file it by hand/machine with male or insert ensat inserts you should activate pre-foro.

Hi.
I have been a solidworks user since 2003 and I have always highlighted the lack of a thread control. since 2013 has been introduced. does a control over the diameter and step. if it detects the interference and if there is a special flag it handles it apart as it does for fixing parts. for this purpose it is good to start drawing the mumps with the tool.
I just passed from 2011 to 2014 and eager to finally use the command I immediately had problems. on axiemi type: a female threaded tube equal to both sides with coupled the same male solidworks pieces correctly manages only one of the two interferences.
the thing has already been reported in America. I hope that in the next releases it is settled but a low priority has been given

Thank you very much for the directions and the tips,

unfortunately not having solidworks under hand I can not try the various solutions, I will have to wait tomorrow (if I pass the fever) when I go to the course ...
