why is it that when I click on ‘end edge of thread shaft’ ‘convert entities is not highlighted, I had the same problem with previous tutorial on embossing text on curved surface. after creating text on plane, the ‘warp’ command was not highlighted. I don’t understand why this is happening. please help

Hi guys,
You welcome…

I was looking at your tutorial on creating a 1/2-13 bolt. I was just wondering in step #7, how you calculated the dimensions of the tooth side profile. I found the tutorial very helpful Thanks. I do look forward in hearing how you calculated that profile, because I wouldn’t know how to calculate it for a 3/8 bolt, or any other bolt. I appreciate any help on this.

I cannot get thread profile to sweep. I’m obviously doing something wrong, but don’t know what. I figure I messed up the thread profile sketch. Any tips?

That was quite useful for me, thanks.

For some reason it won’t sweep
I resketched the profile many times; it always gave me an error without explanation.
Can anyone help me?

This is nice and all but its a bit incomplete, I’m still very new and some of the steps were rushed…

Hi, i just dont get step #7, or actually i dont understand what u have sketched and how to sketch something like that?
Im still new to this, so please reply. Thanks!

Ok…. Lol thats not my problem anymore..
Here’s my new problem: when i set sketch 6 as profile and helix/spiral 1 for the path, then it says “Sweep operation failed to complete.”
So what to do?

The sweep op didn’t work for me until I extended the sketch into the shaft area. It can be extended in any distance, as long as it is not flush with the top of the shaft. If you mirror (copy) the sketch it works great. Hope that helps
