Hi,

I'm trying to create a lip and groove feature on my assembly. (see below)

When i add the lip (manually) on the right side, everythin goes ok. But when i try to add the groove on the left side, it doesn't work. (see 3rd pic). I use the Swept-cut tool for this. 

I tried many things (e.g. the tool, other side etc). Can someone help me please?
