The language ref command DITTO
How many times do you have an ASCII file with point number, coordinates and description key’s ?

How many times have you imported the ASCII file using the points import commands ?
How many times do you need (3d)lines between the surveyed points ?
Off course it is possible to use the transparent command after the 3dpoly command
command:3dpoly
specify start point of polyline:‘pn
>>enter pointnumber: (first point number – last point number)
The 3dpolyline will follow the point numbers range as input, even if one of the numbers in that range is missing
BUT
Using the DITTO command as a toggle
The first instance toggles the command on the second instance off
Just type figure begin and figure name
Ditto command
Ones NE SS
as extra lines in the .txt point file
As the bold text shows in this sample
BEGIN etw
DITTO
NE SS 1001000 150481.179 500553.687 50.659 "etw"

Save the ASCII file as .fbk and ready for use
the result is a automatic figure called etw
was survey always as simple as this sample :-)
more to come ...Chris Berends
