As you can see in my image, I have a problem with this function. I created a sketch that represents the thread section and when I do a Swept boss/base on the propeller, it does the boss for me, but it removes a piece of the inner surface of my bolt.
I'm a beginner on this wonderful software, so be me, I need to learn :)
Thank you
PS: I'm designing this bolt in order to 3D print it, so all comments other than those about my problem are welcome
Which version of SolidWorks are you using? (Different solutions are possible depending on this)
On another topic, what is the purpose and use of the nut once printed?
If it's for intensive use, you can always use a nut (I insist on the word nut :-) ) that you can insert to the rest of your printed part (the behavior will be even better)
If you are in SW2016 you have the function to make 3D nets precisely for 3D printing. This avoids creating all the sketches and stuff and you have the standards like for thread representations.
