Ortho Projection not in scale

Hello,
according to the TFW file it seems like you are exporting the side ortho. Is that right?
I suppose your model is georeferenced. What is the expected height in the model’s area? Is it about 93 m ASL?
When you are placing the reconstruction region before ortho creation, do you have set the upper left corner as reference one?

Have you tried export the ortho set as Image for World file coordinate system?

If not, how does the TFW file look?

This TFW file you sent need to be “rewritten” to get the proper format as in the forum I sent you.

Replace line 1 with line 2, replace line 3 with line 4, replace line 5 with line 6. Change big value to 0 and probably negative value to positive (as this should be the height).

Then the side ortho should be georeferenced according to its height. For the side orthos it is the only way for georeferencing, there is no the position’s value.
