use of the trim command

[Anonymous]

I am confused by how trim works. I have a sketch I inherited from somebody else, some ad hoc shape. I would like to modify it by trimming a couple of lines. I add a horizontal line which crosses the sketch in the point where I want to trim it, but inventor lets me trim only the line itself, I don't find any way to trim the closed shape instead

1. Do you have a sketch pattern?
2. Attach your file here and end all doubt.

Hello,

If I understand correctly, you are talking about derived sketch from anther part. If so, you can't trim the derived sketch. 

Please break the link and then the derived sketch is free to trim.

Hope it help!

hi, thank you for this. I did not have that in the menu, it looked like a self standing sketch already. See the attached screenshot. The green line is added by me, to trim the pink shape, but it didn't let me. I noticed though there was that "projected loop" in the menu, and that does let me break the link, and now everything works!

Hello,

Ah, in this case, you have to break the loop profile before make any change.

Hope it helps!
