ragetoca Posted November 24, 2014 Share Posted November 24, 2014 I bought the book "Residential Design Using X6" while doing one of the exercises I found something abnormal. I drew a 36'-0"x22'-0" room with a living area of 792 SF - BUT when you add interior partitions the living area changes to 790 SF - Have any of you encountered something like this before?

OldCKD Posted November 24, 2014 Share Posted November 24, 2014 Is it simply deducting the thickness of the walls? Link to comment Share on other sites More sharing options...
ragetoca Posted November 24, 2014 Author Share Posted November 24, 2014 I found that the longest interior wall is causing the discrepancy - is that intentional in the CA programming? If it is it then it does not meet ANSI standards Link to comment Share on other sites More sharing options...
Gawdzira Posted November 24, 2014 Share Posted November 24, 2014 I never use that Living area label but I just did a test and it appears that it does not reduce by the interior wall footage. I started adding interior walls and at one point the square footage jumped up one foot then down again. Link to comment Share on other sites More sharing options...
ragetoca Posted November 24, 2014 Author Share Posted November 24, 2014 This kinda scares me - When you build and budget houses by the square footage, how can one trust what CA does with the way it measures the areas? Link to comment Share on other sites More sharing options...
DRAWZILLA Posted November 24, 2014 Share Posted November 24, 2014 Close enough for me and my clients and building departments. Never had a problem with it. Link to comment Share on other sites More sharing options...
ragetoca Posted November 24, 2014 Author Share Posted November 24, 2014 Perry, the issue I see is that is giving different numbers when the numbers should be THE SAME regardless of how many interior walls you add, thats just bad programming IMO Link to comment Share on other sites More sharing options...
DRAWZILLA Posted November 24, 2014 Share Posted November 24, 2014 Could be, but I can live with it. Link to comment Share on other sites More sharing options...
Kiwideziner Posted November 24, 2014 Share Posted November 24, 2014 Read the reference manual on the subject and it should be reasonably clear on what areas are what. Link to comment Share on other sites More sharing options...
rlackore Posted November 24, 2014 Share Posted November 24, 2014 Could be, but I can live with it. Perry, this is my biggest frustration with CA - too many strange behaviors and missing features that we have "live with." I admit that I'm retentive and extremely detail-driven, but surely you can see the OP's point? Link to comment Share on other sites More sharing options...
ragetoca Posted November 24, 2014 Author Share Posted November 24, 2014 My purchasing/estimator director he go nuts if he sees this, anyway, I am still playing with the demo, hopefully CA gets to a point where we can do polyline based areas like in Autocad Link to comment Share on other sites More sharing options...
rlackore Posted November 24, 2014 Share Posted November 24, 2014 My purchasing/estimator director he go nuts if he sees this, anyway, I am still playing with the demo, hopefully CA gets to a point where we can do polyline based areas like in Autocad You can always draw a polyline and query the object for the enclosed area. You can even select a room, automagically generate the room polyline, and there you go. I can't however, control whether CA calculates the area correctly.

Kiwideziner Posted November 24, 2014 Share Posted November 24, 2014 You can now draw in polylines to the specific area you want, these can be shaded or whatever. Link to comment Share on other sites More sharing options...

DRAWZILLA Posted November 24, 2014 Share Posted November 24, 2014 I totally agree, a PLINE based area..... we have been talking about this for a couple of years now. yes, p-lines with labels, that could be used for a lot of things. Link to comment Share on other sites More sharing options...

glennw Posted November 24, 2014 Share Posted November 24, 2014 Why don't you post the plan so that others might see if there is a problem. My bet is that it has something to do with a room definition or the like where Chief calculates the Living Area to the centre of a wall (as designed).

4hotshoez Posted November 24, 2014 Share Posted November 24, 2014 Spaces labled "open" and "attic" are obviously removed from area calcs. But did you know that if you have an attatched garage, the area calc uses half the thickness of the wall. Other wise it use the wall layer to the exterior to figure floor area. This comes from the reference manual. See Perry, I do read it. Link to comment Share on other sites More sharing options...
DRAWZILLA Posted November 24, 2014 Share Posted November 24, 2014 It uses half the wall between the house and Garage and the outside of the Exterior walls to be exact Link to comment Share on other sites More sharing options...
ragetoca Posted November 24, 2014 Author Share Posted November 24, 2014 Look at the files already posted, no garage only interior rooms. When I delete the long walk the sf changes 2 feet Link to comment Share on other sites More sharing options...
glennw Posted November 24, 2014 Share Posted November 24, 2014 It uses half the wall between the house and Garage and the outside of the Exterior walls to be exact Perry, Not quite exact. It depends on your "Living Area To" setting in the Plan Defaults. You can choose either Main Layer or Surface. Link to comment Share on other sites More sharing options...
DRAWZILLA Posted November 24, 2014 Share Posted November 24, 2014 I assume main layer is checked for square footage Link to comment Share on other sites More sharing options...

lbuttery Posted November 24, 2014 Share Posted November 24, 2014 Ragetoca: I see some rooms that don't have labels are they set to "unspecified" ??? I can't see why that would have an effect - just an observation I agree that simply sub-dividing the space shouldn't change the overall sqft post the plan here so we can "play along" also send it to tech support to see what they say Lew Link to comment Share on other sites More sharing options...
