scale photgrammetry
How do we set the correct scale using the photgrammetry tool? We go through the sequence of drawing vertical and horizontal lines over the image and setting the actual dimensions, but then what?
There are two options:
a) Set the scale before beginning the photogrammetry. You can use the normal controls like the button in the lower left hand side of the main window or use Drawing > Change Drawing Scale.
b)
Hope that helps!

- • Continue the photogrammetry with the current scale;
• when you are finished with the photogrammetry tool, save the projection as a new document;
• open that new document and change its scale. Since all the points are projected analytically, there is no quality loss when you change the scale afterwards.
Hope that helps!
