That is funny Cathy. They are nothing close. Even so, that utility I did not adjust. 0 is 0 and that is what I used in the function.
Here is the deal. The 3D solid that was exploded and the lines were retrieved from was, I believe, 2" x 3/4" x 5000" So I had a ratio of 5000 to 3/4, maybe. Acad will fail, at about 220 to 1. It was an exaggeration test part to reproduce the error easily. The exact number is somewhere in between 223.6 and 223.61 to 1 ratio.
Try this:
If you draw a line.....
Starting at the first specified source point, "10.3688159,-30.95757643,34.08858268"
Then the second specified source point, "-10.3688159,-30.95757643,81.91141732"
Then the third specified source point, "-10.56566629,-30.95757643,81.91141732"
you will get an inverted "L" in modelspace.
Now try to align it with:
First destination point: 0,0,0
Second destination point: 1000,0,0
Third destination point: 0,1000,0
Seriously, I think some programmer used an existing error message for a known bug, but never wrote the correct error message to hide fact he had not fixed his bug or actually forget to fix it.
All said and done, I forced the issue and it works. I have again found another way, thanks to Mick, and if successful in testing, this new way will much faster and more reliable.
Take care,
Dave
