Im currently working on a student version od inventor 2012 ( proffessional). Im working on a shaft (on design accelerator) and when I add a feature such as a keyway groove or a retaining ring i can see it on the "preliminary view" but when i click accept and inventor builds up the shaft it simply dissapears. I have tried several things, such as closing it, creating a new shaft, adding a different feature ( same result), turning my computer off.
One of the main frustrations i have is that this problem came out suddenly, i was working on inventor and it was working correctly ( showing the features) but suddenyl i tried to edit the shaft and thats where the problem started.
Another important thing to know is that when you edit the shaft using design accelerator you can see( on the preliminary view) that the feature is endeed there.
Thank you very much.
