When i draw with 2D plumbing line a make a change in direction MEP 2008 puts an elbow in the corner of the line - this elbow is put in a different layer than the 2D line and (according to danish layer standards) this layer is thinner than the line which not look good.
When i choose a tee i have several options one of them is None but in the elbow options i can't choose None (i would like to make the direction change without an elbow).

Are there anyone that can help me with this problem?
