Hi DeSchlong,
I am glad you have solved the problem. To make future use of this tool easier, I have proposed an enhancement for this tool to include a new parameter, Flow Direction, with the following choices:
NONE - the default, flips all input lines, as the tool does currently.
DOWN_Z - flips a line only if its starting Z < ending Z, so that the line runs down-hill.
UP_Z - flips a line only if its starting Z > ending Z , so that the line runs up-hill.
DOWN_M - flips a line only if its starting M < ending M.
UP_M - flips a line only if its starting M > ending M.
You have a new case, so perhaps we can include the CW and CCW choices as well. These choices should only apply to closed lines (contours), correct? Do you or other users have additional thoughts on this?
Thanks for your input.
