I am trying to delete fill from a sketch I have done on a drawing. (See attached). Unfortunately I cannot find any way to delete without deleting the whole sketch. I tried as Inventor help said to go into Annotate Ribbon and change Layer & Style but both these dropdowns show blank when I try that. I also tried going into Fill/Hatch again hoping the new one would overwrite the old one but no success.
I am using 2012 and what works for me is if you edit the sketch that has the fill, select the fill/hatch region command on the ribbon and uncheck the fill button. This removes the fill.
I have re-done a simple sketch on a new drawing and it works fine and can switch between fill & hatch. It must be something corrupt with the sketch I have. I will delete and re-do it on my proper drawing. Thanks for your input Cadmanto.
This is an old thread but the same thing has happened in Inventor 2015 to me with a drawing sketch that took me a long time to prepare. As in your case, the suggestion from Cadmanto didn't work, but I accidentally find a workaround.
If you relax some constraint to open the area where the hatch is cointained, it will dissapear.
This saved me A LOT of time!
