exterior walls

[mashick]

I have a old house that has been added to several times. With the additions some of the exterior walls have become interior walls of the newer space. Also, the exterior walls  have several different outer surfaces. How do you make different walls have different exterior surfaces? I have tried to break the walls but when I change one exterior wall the entire exterior changes.

not sure why you are  breaking walls unless one wall has two different materials on different sections ? but you should be able to change any walls exterior material in the Walls DBX under materials.

It may seem to you that perfection is the goal. I would suggest to you that accuracy is the more important factor and they are NOT the same thing. I am and have been doing remodeling projects professionally for a couple of decades and for remodeling projects where you have an existing structure the key areas that need to be accurate are those directly adjacent to areas where additions and or renovations are to occur.

The rest of the house is merely a "backdrop" for the work area.

In other words, areas that you are not building from scratch merely need to not detract from the communication of what is being changed or added.

 

A virtual model is vastly different from an existing structure in its basic character   (computers are best at straight lines and angles unlike the "real" world where machine perfection is not a constant by default).

 

The point of construction documentation, drawings and renderings is to convey what you want done to others. Competent building professionals already know HOW to build, there are existing codes, inspections and procedures to curb a sometime lack of personal ethics or someone's "bad day" at your expense. Plumbers, Electricians and HVAC specialists are also State Licensed so your most important thing to do is to find a General Contractor who has a demonstrated track record of competence and honesty (they are out there along with the ones who give the rest of them a bad name).

 

Make sure the addition is accurate (it will have to have a foundation designed by a State Licensed Structural Engineer or for smaller room additions a State Licensed Architect will serve) and inaccuracies at that stage of the project can be expensive to repair and cause delays.

 

If you will give us a little more to work with, in terms of data about your concerns, we are glad to help but we have to understand the  problem to supply useful answers, post a picture or pictures, say what software you are using and its version number.
