Try to use the "Gusset" command under the dimple command in sheet metal,
make the bend first and then use this command, point at the inner radius of the bend
then you can place the "gusset" where you like, You can even choose parameters for the gusset.
@Aviad If a someone provided a solution to your question, would you mind marking their reply as the Solution? This will help future community members when searching for an aswer to the same question.
Great, and as the user that asked the question, you can mark his answer as the solution. You should see an "Accept As Solution" button on Tushar's reply... Click it to accept it as the solution.
Yeah, I gotta back Ken up here. It's really helpful when you mark answers as such, because the next time someone has a similar question, we've already got an answer for them. So if someone helps you out, pass it on, and pay it forward a little. Some day you'll be the one answering questions, and you'll want to get a little credit.
