it shows an error in the miter bend when i try to flatten the attached box.Can anyone can solve this@Dennis Bacon
Sabareesh,,, It looks like you were on the right track since you had a dimension on sketch of 0mm. If you delete the coincident relation at the top and change your 0 to .001mm this works. Looks like the flanges are merging at the top.
Thank you sir,very helpful
