Chimney changes profile, tapers part way up

I have a renovation project where I am doing as built drawings for demo etc.   There is a fireplace on the ground floor that is quite wide.  The chimney protrudes out through the exterior wall, which is brick, and at the second floor, the chimney narrows down from a rectangle to a square before going through the roof plane.

 

How can I do that?

Make a brick out of psolids, assign it a special material you found on line.  Add a mortar layer around it.  You will then isolate it on a 3d view and create a symbol.  Now place it in the plan with an elaborate cut and move process.  Make sure you use a macro to give each brick a separate label.  You will want to back this all up on a ssd and link it to your dropbox account.  When you have completed the new fireplace, block them all together and create a symbol of the completed unit.  Make sure there is another macro that automatically names it in a way you will never be able to figure out again.

   I'm just kidding of course.  Eric had it right.

Chief has never handled fireplaces very well, p-solids are it

 

Perry:

 

I agree and have never understood this ?

 

Chimneys have been around for 1000's of years

there are some very common designs

 

there should be a chimney tool that can create these standard shapes via dbx settings

 

I have been suggesting this since I started in 2004

 

CA - please get this feature added soonest

I saw a comment about fewer chimneys due to high efficiency gas appliances but fire places are still prevalent in single family houses. Most of my work is renovation so I have to duplicate what is there now. 

 

I am not sure about how to use poly lines because I a a noobee to AC

I personally think this would be something covered by better generic modeling tools.  In 20 years of designing about 800+ homes I can remember about 2 brick fireplaces - though many more masonry block/rock fireplaces.  I think the design/types/methods of all the options out there would make a "tool" in a Dbx for this very difficult.

If you are New to CA ..then it's a good Idea to get to know the Reference Manual but the Online Tutorials in the KnowledgeBase (KB)  are helpful too

 

eg : they aren't making a Chimney but the principle is the Same....

An old trick was to just use Walls and a Wedge from the Library like this old practice plan of mine: added a poly-solid wedge for you to play with too....

I'm with Johnny on this for sure.  Here's what I would prolee do...

 

 

I didn't go over it in the video but there is quite a bit more that could be done to further perfect the object for different views and view types depending on what a person was after and the object could also simply be converted to a symbol once completed.  Anyway, hope this helps.

Funny, I've seen about 4000 masonry chimneys, they are in just about every remodel job I do.

It's about 60/40 for me with the majority prefab fireplaces.  

 

Masonry fireplaces are a big problem if the chimney height needs to be increased.  Most of the time it is more cost efficient to tear it down and put in a prefab.

 

I think I have extended the height of a masonry fireplace maybe twice...  a big hassle.

Thank you for this example of how to handle the chimney problem.  Great tutorial and advice.

 Yep around here in Los Angeles county you have to extend masonry fireplaces using metal studs and stucco exterior with a metal flue liner (5 page detail), so it is easier to tear down and rebuild. Also a lot of cities around here are not letting wood burning fireplaces at all. Air quality issue. But I still have to model the old fireplaces on the plan. I have extended many many masonry fireplaces, just hope you find rebar when you do.

I think I deal with more older homes around here.

Crazy good video Michael.  Though, I was a bit disappointed you didn't go on to model the clay liner or smoke shelf/chamber....lol :P:D
