Error: Failed coilfunction for knurling.

[jorbakken]

Hi. 

Happy new year everybody.

I`m trying to make a knurly pattern on a knob using the coil-function, but I get an error-message either by making the first half revolution or by mirroring it. 

I get two different errormessages. Either: 

or when I finally get a line and try to mirror it; 

 I`ve tried to change patterns upwards and downwards. Making a new "target body" to see if I`ve done something wrong with the first object. Searching and speculating for answers. I`ve seen several videoes on youtube and it looks like this should be a easy thing to manage. 

Does anyone know if I`m doing something completely wrong or if it`s a issue with the Coil-function?

Hi,

Hi Günther.

My plan was to do like in the video: coil- mirror - circular pattern. The problem (like I showed in the screenshots), is the error messages I get both when I use the coil-function for cutting and the mirror-function for copying, wich means; I don`t have at base-pattern to transfer to a circular pattern. The problems occures before I get to the circular-patterns-function.

Hi,

Watch the screencast and play with the coil data, especially the coil height.

Pay attention to warnings!

Thanks for taking the time making the video.

I tried doing it exactly like you did, but I still get the error-message: 

As you can see the sketch is a bit shifted compared to the body, but like you, I just move the body in position when editing. I tried altering revolutions from 0,25 to 1 and section size 1 to 2, but it`s still the same error-message:

..and I also experimented with the hight.

Hi,

1. follow the timeline in shared file

2. start a new design

3. service utility > Repair

Hi.

I tried the repair-function. That was a good suggestion, but it`s still the same:

Maybe I should try to delete Fusion and reinstall it? I don`t know. I`ve been going at this for weeks now... I just can`t wrap my mind around what the problem might be.

Hi,

In the screencast, I show you how to remove “distracting” areas and mirror profiles on a previously defined plane.

Hi. 

I managed to get the knurling stick to the cylinder when I did as in your latest screencast. I guess I made a mistake by doing something to the sketch for the knob in the original drawing, cause when I see turtorials it`s so plain and easy to get the knurling stick to the body. I`ve got me some knurling and that`s way better than getting nothing at all! Maybe I`ll just start all over again cause I struggle to see the mistake and repair it. I still got some error-messages, but now I got something to work with. 

If I recreate the sketch for the body.... I will for sure mess up elements in the timeline, but if I can restore a correct sketch it might fall back in place? Do you know if that`s doable?

Hi,

In such cases, it is usually better to start from scratch.
That way you have a clean basis and can prevent “damaged” features from being the cause of the error.

Hi.

I started all over again and used some of the know-how you shared. The test on the picture doesn`t have the perfect surface, but as a knurling-test it came out just as I wanted it. A threaded crank-holder connected to a three-way gear. 

Thank you for your help and patience!
