SNestor Posted June 20, 2014 Share Posted June 20, 2014 Wondering how to construct a fireplace chimney. According to the CA help you can use the soffit tool and apply materials to it. However, this would not "frame"...would it? Is it typical to construct chimneys in this manner? I have an outside chimney chase...3 walls. The house is 2-story on a basement. The basement extends under the 3 outside chimney chase walls. The chimney is brick veneer. The chimney needs to extend above the 2nd floor top plate maybe 8'-10'. 1st floor has 10' tall walls; 2nd floor 9' tall walls. Floor system for both floors are I-Joist...14" deep. I have drawn the walls for the chimney on the 1st and 2nd floors...but not sure how to go from there. I know...I need to post the plan. I can't do this right now...I'm at my day job. I will try to post (if I can figure out how) - although it will probably be tomorrow. If there is a thread or two somewhere that will help me please let me know. Thanks!

CJSpud Posted June 20, 2014 Share Posted June 20, 2014 Go up into the attic and draw your walls there ... make a room and give it the desired ceiling height .... or draw the walls on the attic level (they should want to stay under the roof unless you make them do otherwise ... then in elevation views (backclipped) drag them up one at a time. That should give you the framing. Make you wall definition whatever it needs to be for materials. You may need to use a PL solid for the cap. Post your results when you get it figured out. I got something similar I need to do with a plan soon. Link to comment Share on other sites More sharing options...
dshall Posted June 20, 2014 Share Posted June 20, 2014 .... or draw the walls on the attic level (they should want to stay under the roof unless you make them do otherwise ... CAN'T HAVE A ROOM DEF ON ATTIC LEVE, CREATE A NEW FLOOR then in elevation views (backclipped) drag them up one at a time. .....SILLY, JUST GIVE THE SPACE A ROOM DEFINITION AND CONTROL THE HIEGHTS VS THE CEILING HT. This is a great question, I have fussed with this on multiple occasions and for some reason it never works for me. I usually create the chimney out of a solid. I know, not a good solution, I know it does not frame the walls...... i will give this another go, it should not be too hard. Link to comment Share on other sites More sharing options...
CJSpud Posted June 20, 2014 Share Posted June 20, 2014 Scott: I will have to experiment with your technique of adding an extra floor and not fussing with attic walls. What I am wondering about regarding my suggestion is, if attic walls don't provide room definition, then there shouldn't be any 3rd floor framing to worry about. I am going to go do a quick test and see how this might work. Link to comment Share on other sites More sharing options...

There always seems to be some minor snafu that does not make the exercise worth doing. I use PSOLIDS for the chimney chase, not ideal by any means, but I just can't get the chimneys to work for me.

lbuttery Posted June 20, 2014 Share Posted June 20, 2014 you would think that Chief would have a chimney tool they have been around for "thousands of years" and common to construction the tool could also have settings for common styles with flare on left or right or both etc I've been suggesting this for almost a decade guess CA's not listening Lew Link to comment Share on other sites More sharing options...
CJSpud Posted June 20, 2014 Share Posted June 20, 2014 Scott: This was so easy, I think I could have done it in my sleep. I did it the way I suggested ... just 4 attic walls joined ... your right, no room def ... that was good as there was no floor framing at the top ... drug the walls up in elevation views (the roof didn't chop them off ... they were sticking out already - Great .... put a PL solid lid on the top of the chimney walls ... found a couple of chimney tops in the library and got them positioned as shown.

dshall Posted June 20, 2014 Share Posted June 20, 2014 ......... (the roof didn't chop them off ... they were sticking out already ....... Chimney2DAtticPlan.JPG Chimney3DFullOV.JPG Chimney3DFrmg.JPG ChimneyXSection.JPG I am surprised the roof did not cut it off.... did you hit f12 to rebuild, if you did, I think the roof would cut off the walls. Not a big deal if the roof cuts off walls, all you need to do is put a hole in the roof platform and the framing of attic walls will pop thru. Nice job if it is truly working. I am loathe to drag walls up and down in elevation, don't know why, probably because I am anal, but if it works, good, but it should not be necessary, we should be able to control the height via the ceiling height default.... which of course needs a room def.

CJSpud Posted June 20, 2014 Share Posted June 20, 2014 Scott: No, I didn't F12 the roof to see if it would chop the walls off. But, your idea of cutting a hole in the roof would probably solve that issue if there was no need to add an extra floor such as you do. Link to comment Share on other sites More sharing options...
Kbird1 Posted June 21, 2014 Share Posted June 21, 2014 True Brick Chimneys don't have framing but not sure what the OP really wanted ?......However it might be done this was for "the look" , a framed chase is usually only done for B-Vent type chimneys , otherwise it would be double (masonry) layer brick. Might use "Cultured Stone" on a framed wall these days I guess too.... Scott's idea of the extra floor should work too , it is the same method used to do Custom Cupolas , you just have to make sure to derive the extra floor from a BLANK plan or it doesn't work. Not sure if it works if the Chimney is "outside" the building though, haven't tried that part. http://www.homedesignersoftware.com/support/article/KB-00869/52/Home-Designer/Roofs/Creating-a-Cupola.html If you build the Chimney as you Build the House it is pretty painless though whether brick or ??? , didn't try too hard with this example when I tried it out a while back but you should be able to add slopes etc with "Shapes" too . No doubt someone has a better method too ?, but I could see how a "tool" would b quicker though and there'd be no need to build it as you build the house..... you could however "pull" the walls up in elevation if you forgot, using this method from the basement too I think. here is the X5 plan which includes my "how to" to myself.

dshall Posted June 21, 2014 Share Posted June 21, 2014 Kbird, this is something that has bugged me for a long time...... (Framed chimney chases). I can't believe I can not make it work but every time I try there is a glitch. I am going to try again tomorrow. Link to comment Share on other sites More sharing options...
Kbird1 Posted June 21, 2014 Share Posted June 21, 2014 The technique I used above works for Framed Chimney Chases as well , just tried it to make sure on the plan I posted above , and it does work for adding a chimney after the fact too if needed, which I hadn't tried before. I'll attach the new plan too. Only downside is in section view you'll see the interior wall of the chase against the house , so you'd need to remove those lines in your section detail. I used a text box on my .plan to make notes originally so the "How To" is On the plan. Updated on One level if adding afterwards. Your trick of the extra floor isn't needed but , maybe it could help ? have a look on the new .plan , You or Glenn can no doubt modify my technique and make it better, being you ( and others) here really know the inner workings of CA.

DRAWZILLA Posted June 21, 2014 Share Posted June 21, 2014 If the fireplace is metal than I make it out of rooms, if its masonry then I make it out of solids. Link to comment Share on other sites More sharing options...
Kbird1 Posted June 21, 2014 Share Posted June 21, 2014 Because of the double wall in My Method you may need to increase the depth of the firebox to get it to show properly or it may show one of the wall layers in the opening instead. The fireplace will cut its own hole in the wall , just use the Ctrl Key to position in the wall. M. Link to comment Share on other sites More sharing options...
SNestor Posted June 22, 2014 Author Share Posted June 22, 2014 Attached is the CA plan file I am trying to build the chimney chase in. Also, I've attached a PDF of the plan file I am attempting to duplicate. This plan was created with Vertex BD...a supposedly high-end cad software for production builders. It's the software used where I work.The walls on the outside of the chase are 2x6 with brick veneer. The wall between the living area and the chase is a different wall type. I have the walls built on the first two floors...but, not sure how to build the top of the chase above the 2nd floor top plate.I have read the comments on this thread...maybe building a 3rd floor is the answer. Have not tried yet. Estridge Plan 1.plan.zip Link to comment Share on other sites More sharing options...
Kbird1 Posted June 22, 2014 Share Posted June 22, 2014 Scott did some Video's ( see link ) but if the Firebox is on the interior you need the 3rd (Blank) floor , if it is exterior chimney ( think so in your case) you don't , but need to cut back the roofline and add the inner "no locate wall ". https://chieftalk.chiefarchitect.com/index.php?/topic/1319-chimney-framing-videos-by-dsh/ Link to comment Share on other sites More sharing options...

lbuttery Posted June 24, 2014 Share Posted June 24, 2014 Creative combinations of different objects such as fixtures, soffits, walls and wall openings allow you to create a wide variety of fireplace and chimney designs. Hmmm, a dedicated chimney tool would be so much nicer Lew Link to comment Share on other sites More sharing options...
Kbird1 Posted June 24, 2014 Share Posted June 24, 2014 Yep , not sure why the Fireplace Tool was never expanded so you could do the chimney too , or why it can't do "chases" M. Link to comment Share on other sites More sharing options...
SNestor Posted June 24, 2014 Author Share Posted June 24, 2014 The suggestions are helpful to me just for learning how certain things can be accomplished....such as using the cabinet tools to create the mantle and the soffit tool to construct the hearth. However, the example is simplistic. The fireplace I am trying to model is outside the structure and has basement walls under the 3 outside chase walls...which have brick veneer. I did not know how to create the opening for the fire place itself...use a window. Cool. I used a door opening. But, with a door opening you have to be happy with a flush hearth as the firebox will be on the floor. Using a window opening you can have a raised hearth. Between Scott's videos, comments here in this post and the CA help I feel I did get the chimney modeled correctly...and learned a lot of tricks that could help me in the future. Thanks. I'll be back for more I'm sure. Link to comment Share on other sites More sharing options...

You can raise the sill of a door to any height you want. It doesn't have to sit on the floor. Link to comment Share on other sites More sharing options...

Brick Chimney Example_X5.plan thanks @Kbird1 . It worked well, just have to make sure the sides walls of the chimney are not actually connected to the main wall and the no locate wall has the outside layer to the outside(i.e. follow your instruction carefully and this problem does not occur as you make the room and then move it). otherwise it looks like this with the studs showing: and done correctly: Link to comment Share on other sites More sharing options...

Usually the main wall would continue up. Alternatively to your solution you can break the house wall at the connections with the side walls of the chimney, then open that wall section, select the roof panel, then select 'lower wall split by butting roof' and apply the proper wall types to the upper and lower sections.
