wall intersection problem?

valar morghulis,

i am still confronting this auto extended lines sometimes. 

what is the reason of these? 

how can i eliminate? 

it should just be calm and stop where it touches the other main wall:

the reference lines will always try to join, and associated bMats will try to intersect based on priorities. You can fuss with reference line possition and junction order, but the easiest solution is to have 2 wall layers, put one layer on layer group 1, the other on layer group 2. the two layers will not interact with each other until they have a layer combo with the same group number.

For me, I find it the easiest and most practical to add another layer called Wall 02 and set its intersection priority number to a number different from the number of the layer that contains the rest of the walls. This way they won't intercept each other.Change This for The Other Wall Layer.

Are their bases at different elevations?
