On many of our projects the local coordinate systems create long (seven-digit plus decimal places) northing and easting coordinates.  For most projects, only the last four or five digits vary across the site. Prior to LandFX we used a script that one of our staff created for inserting nothing and easting callouts that had a setting for truncating the inserted coordinates from the left by a specified number of places...(i.e. 672,451,983.66 could be truncated by 4 numbers to 1,983.66) We then place a note on the sheet indicating that all the coordinates begin with 672,45...).  It would be really helpful to have this ability to truncate the n/e numbers within the LandFX system (for both the table version of the Northing and Eastings and the Site Callouts version which is our office standard. 

 

Thank you 

Daniel,

 

You can do this by setting a UCS and the USERR3 system variable.

If USERR3 is set to 1, then Northing/Eastings will respect the UCS:

Thank you for your response Jeremiah,

So, if I understand correctly we would set up a UCS to offset the origin to create the truncation? I.e. from my previous example, if we want to truncate an easting of 672,451,983.66 to 1,983.66 we would locate the origin 672,450,000 further east and do similar for the northing. I assume we would do this when referencing our base file into the drawing in which we will be placing our northing and eastings and then set USERR3 variable in that drawing?  Since other disciplines, we will be sharing our files with will be using the WCS on which the topographic survey is based, can the drawing into which our northings and eastings will be linked remain set to WCS?

 

 

 

 

Daniel,

 

That is correct, you would set a UCS as such, and then set USERR3 to 1 in the drawing you will be placing the callouts.

The topo survey, which would be an xref, would not need to be changed at all.  So the UCS and USERR3 setting are only in the top level drawing.
