You're welcome Bob.

You can use the info tool 'Distance Point to Point' to measure the diameter after import (menu Tools -> Info).
https://librecad.readthedocs.io/en/latest/ref/tools.html#info

Then calculate the scale factor: 24 feet / measured diameter

And use the tool Modify -> Scale to scale the drawing.
To proof, you can measure the pool diameter again.

Sadly, there is no one click solution for this.
