🏠 How CAD roof pictures are scaled
Any CAD report or CAD drawing that incorporates a picture of the roof draws the roof to best fit between the extents of the diagonal line input on the template on layer 999.
(Refer to the manual section on defining CAD templates.)
The roof picture may be further constrained by a “proper” scale factor so the picture can be compared with other drawings of known scale.
Example:
If the best fit across the page is 1:187, that is not usually useful to compare, so the software automatically adjusts this to 1:200 (if that is one of the scale options you have set).
🔢 Default scale options
The range of scale options is defined in the software as:
10; 20; 50; 100; 125; 150; 175; 200
🧾 Defining your own scale options (Scales.dat)
You may also define other scale options by listing scale values in a simple text file.
Requirements:
File name must be: Scales.dat
File must be in the: ..\User folder
File format must be like this:
50
100
115
125
150
165
175
200
END
Important: The word END at the bottom of the list is essential for it to work properly.
🔍 Using an unscaled roof picture
You may also have the roof picture included totally within the entire text box at what would essentially be a random scale.
For this, use the Key Text String:
