Hi,

I'm new to using BIM and I am currently on 2013 version.

I've looked through the forum and the HELP and can't find the answer to this question anywhere therefore it's probably really easy but the answer illudes me.

How do I consistently clean up an intersection between an exterior wall (Brick,cavity,{block},plaster) and a separating wall (plaster,block,cavity,{block},plaster) where {} is the structure and where the exterior wall creates an L shape and the separating wall turns that L shape into a T shape. *If you understand that!!* Check out first picture below.

This first picture shows what I want to happen (existing.jpg). However I have the same detail in another part of the building (T Join.jpg) and it doesn't cleanup! How can this be? I've tried the Wall Joins command and i've tried fiddling around with the Layers and Function in the Edit Assembly for both wall types which is how I managed the first, correct, intersection. Would the height of the wall affect the join in some unfathomable way.

My second query regards a similar intersection (problen join.jpg). How do I cleanup the join so that the insulation is continuous?

Thanks

There is no easy way to clean up cavity walls at a T intersection. 

1. You can split the middle section of the crossing wall into seperate pieces and use a wall without an interior finish.
2. In plan views, you can add a masking region.
3. You can edit cut profile.
4. You can add a vertical face based void that cuts the crossing wall the depth that it needs to be.

It looks like you have two walls in the crossing and i bet the other view is continuous.

Hi,

I have been struggling with this also,

I have figured out that if you set the brickwork(say its a 90/50/90 wall) to finish 4, not structure for both walls and have both walls inside the core boundaries it does work for T intersections but not piers. not sure how this affects footins yet, they never seemed to behave properly anyway - my work around was to have a single leaf wall locked to the outler leaf as the brick up and host of the footing to avoid footings at 2 heights that i got using a base extension. your internal sinlge leaf walls will then need to be finish 4 as well. Autodesk are welcome to fix this any time they like!

open to ideas from others,

cheers

I forgot to add, i have abandoned the finishing ( gypsum etc) for floor plans dimensions were getting confused and it was of not huge benefit in cavity brick walls

I set my walls to render with brick hatch so any 3ds are usable

stud frame  i use finish 4 for the stud and finish 5 for cladding

cheers
