measuring length for a structure

[whatsarobut]

Is there any way to measure the length and width of a structure in photoscan based on just x,y data (no height).  I attempted to manually input 4 control points (corners of a square building), but it would not let me draw a scale bar based on those. I do not have the camera's gps positions.   Anyone have ideas?

Hello whatsarobut,

In case your model is unreferenced and not scaled, you cannot perform any measurements.

To create a scale-bar you need to select two markers, right-click and choose Create Scale Bar option from the context menu.
