Model Builder / 3D Model View - Old Model still showing up

Question

Hi Shane 
 
 Hope you are keeping well?. 
 
 I am wondering if I might be able to call on your expertise again. 
 
 I am having issues with a model I have drawn up. 
 
 The original model was done about two years ago. The building has since changed layouts. I have uploaded the new dxf and traced in the room. 
 
 When I go to view the model in 3D viewer I can still see the old Model (Marked with and X in the snip.) 
 
 When I deselect a floor in my new model is also deselect thhe corresponding room in the old Model , its like they have been linked together. This is the same for the 2 nd floor. 
 
 The first floor seems to be ok. 
 
 What I am worried about is when I run a heat loss simulation will the doublicate rooms be getting mashed or read into the new model causing a faulty results reading. 
 
 When I go to the heat loss program I can see the old rooms from the old model.

Would you have come across this before , if so is there any trick to fix this or is it a case of re starting over?? 
 
 Any help is greatly apreaciated.

Kind Regards 
 
 Seamus Murphy

Hi Seamus, 
 I'm good thanks, hope all's well with you. 
 When you enter a new DXF into an existing model (ie as shown here ) the model will not be impacted. Any traced rooms will remain, just with the new DXF background. 
 I suspect two things have led to your confusion: 
 1. It sounds like your new DXF had a different origin point to the previous one, that is why the floor plans appear far apart. 
 2. It sounds like you have then traced duplicate rooms over this new DXF 
 If the above sounds like it could be the case, then you would need to firstly back up the project as it is, and then delete the duplicate rooms. If you have difficulty zooming to the duplicate rooms due to the now very large area of the floors, you can user Find Room as below: 
 
 Hope that helps. 
 Regards, 
 Shane

Hi Seamus, 
 Good to hear from you, I hope you're well. Be happy to help - that's what we're here for! I'd just create a new thread next time if you need anything, as replies to old ones can be missed sometimes. 
 For your building you will need to do as follows: 
 
 Exposed roofs must be traced and then setup over the relevant floor so I would what you suggest sounds right to me - i.e. I would ' Add a new roof drawing ' for each floor, trace the sections above that floor, and then setup exposed roofs as below - ensuring to select the correct floor, and omitting any internal rooms not below the exposed roof: 
 Next, Hevacomp won't recognise rooms above/below automatically - so you will need to instruct it to do so by setting up intermediate floors as below: 
 
 Going forward, I'm not sure if you have tried out OpenBuildings Energy Simulator yet, but I would say such buildings would be easier to model using it, as it a utomatically creates flat roofs for each room , and automatically recognises if there are rooms above/below , and converts the surfaces to ceilings/internal floors accordingly . So there is no need for manual intermediate floor/ceiling setup, or tracing of roof sections for flat roofs. 
 Update 9 will be out later this quarter and will include Ireland PartL, so it may suit to test the waters at that stage.

Hi Murphy, 
 OpenBuildings Energy Simulator is a new package offered by Bentley, subscribing to which you will have free entitlement of Hevacomp. Energy Simulator is more advanced than Hevacomp, as it is built with the connect edition, which is upgraded from v8i.
