Horizontal Floor Plan Same Size as Vertical Cross Section

Horizontal Floor plan Vertical cross section
A client has a very unusual floor plan. The 2D floor plan is a PNG file on the red-green plane. The cross section is a PNG file parallel to the blue axis. How do I size each of them so that the measurements on the floor plan match up with the measurements on the cross section?

For exact scaling - Tape Measure

If it has dimensions you could draw a line from the beginning to the end of it, select the image and the line and create a group, get into the group and with the Tape measure toot, shortcut “T”, make a click at the beginning and at the end of the line you drew previously, without exiting the tool type the measurements of the dimension you see on the plan and hit enter, a pop up window will appear asking if you want to change the dimensions of the group, just accept and you’ll have the plan scaled properly, do the same with the other image and both will have the same scale. If you don’t have dimensions you can search elements with standard measurements like a door for example, draw a line there and repeat the process, but it’s better to use a longer distance to be a bit more accurate. With an image the scale won’t be 100% exact cause of the pixels but it’s pretty close to the real dimensions, if you have dwg plans of the project it’ll be more accurate since you have lines without width, just vectors, and you’ll have the right snapping points to use the tape tool.

If you have problems with it you can share the images and I could make a video of how to use the tool and send you back the skp file with the drawings scaled.
