Facade Measurement, how does it work ? ?

On the site, you have to position 2 aluminium rules (whose exact length is known), one vertically and one horizontally, and then take a photo of the facade... That's all!
Later on, you can easily make all the required measurements from the comfort of your office.   

Once back at the office, simply create a new project and load the photo. 

Pixdim automatically corrects distorsion and runs the reference line definition command (perspective lines).

Define 8 points to determine 4 lines, 2 horizontals and 2 verticals.

Define the two reference dimensions (on the two rules). 

That's it! Pixdim creates a new Google SketchUp page in which it will automatically modelize all the measurements that you have made.

All points and rectangles measured are automatically modelized in 3D page.
